NATURAL HERITAGE PROGRAM LIST OF THE RARE PLANTS OF NORTH CAROLINA
North Carolina has an exceptionally rich and diverse flora, consisting of about 5600 species of gymnosperms, dicots,
monocots, ferns, fern allies, mosses, liverworts, hornworts, and lichens. North Carolina's flora includes boreal plants
— more typical of Canada — on the high peaks of the Southern Appalachians, subtropical plants (including palms)
in the maritime climate of the barrier islands, tropical ferns, mosses, and liverworts around waterfalls in humid
mountain gorges, as well as more typical and characteristic species of the Southeastern North American coastal
plain, piedmont, and Southern Appalachian Mountains. In addition to those mentioned above, some of the more
notable habitats of rare or endemic plants in North Carolina include longleaf pine savannas, mountain bogs and fens,
sandhills, piedmont glades and prairie-like savannas, mountain cove forests, coastal plain limesinks, granite
flatrocks, and pocosins. The diverse native flora of North Carolina is a rich part of our natural heritage, worthy of
protection for environmental, scientific, economic, aesthetic, and moral reasons.
The North Carolina Natural Heritage Program (NC NHP), as part of its mission to preserve the biological diversity
of North Carolina, maintains a systematic inventory of all known locations of rare species. The following list of rare
plant species, monitored by NC NHP, includes739 species. All plant species native to North Carolina which are
officially recognized by federal or state agencies as protected or otherwise rare are included on this list. This list
incorporates the most recent federal status of rare plants, as determined by the U.S. Fish and Wildlife Service
(USFWS) and published in the Federal Register on September 30, 1993, with later amendments current to January
23, 2002. Natural Heritage Program List of the Rare Plants of North Carolina also includes North Carolina legal
status information from the most recent version of the List of North Carolina's Endangered, Threatened and
Candidate Plant Species, published in January 1994 by the North Carolina Plant Conservation Program (NC PCP),
which includes discussion of and information on the legal status of Endangered (E), Threatened (T), and Special
Concern (SC) species. Additional updates to the PCP list are available on their web site
www.agr.state.nc.us/plantind/plant/conserv/cons.htm. The North Carolina Plant Watch List includes an additional
500 species, which appear to be rare enough to be of conservation concern in North Carolina, but which are not
currently inventoried by NC NHP, and are not legally protected or active candidates for legal protection by the
USFWS or NC PCP.
NC NHP takes the lead role in North Carolina in the inventory of the state's natural diversity, the identification of
important natural areas and rare species habitats, and the protection and management of natural areas. It serves as
the state's data bank of locality information of natural areas and rare and endangered plant and animal species. It
conducts environmental reviews of projects involving state or federal permits or monies, to minimize negative
impacts on North Carolina's natural areas and rare species. Many species which lack formal, legal protection are
nonetheless imperiled in North Carolina. Therefore, NC NHP collects data on species in addition to the three
categories of protected plants (Endangered, Threatened, and Special Concern). These additional rare species are
placed in two other categories of rare plants: Significantly Rare (SR) and Watch List (W). Definitions of all status
categories are listed below, under "North Carolina Status." NC NHP requests locality and population data on the
species listed in this publication. A plant field form has been provided as an addendum for this purpose.
NC PCP, a unit of the Department of Agriculture and Consumer Services, is the agency responsible for the listing
and protection of North Carolina's endangered and threatened plants, under provisions of the North Carolina Plant
Protection and Conservation Act of 1979 (General Statutes, Article 19B, 106: 202.12-22), as amended. NC PCP
acts under the direction of a Plant Conservation Board and with the advice of a Scientific Committee to maintain and
revise the state lists of protected (Endangered, Threatened, and Special Concern) plant species, to investigate
protection needs and survival requirements of native plants, to carry out conservation programs, to make and enforce
regulations, and to issue permits concerning protected plants. The 142 plant species currently listed as Endangered
and Threatened in North Carolina are published in the List of North Carolina's Endangered, Threatened and
Candidate Plant Species: January 1994, with amendments, available from NC PCP. The address is listed at bottom
of title page. That publication also lists North Carolina's Special Concern species and explains regulations and
permits regarding protected plants. In general, removal of Endangered or Threatened plants from the wild and their
sale or distribution is illegal. Particular regulations concerning collection, propagation, and sale apply to those
species (Endangered, Threatened, or otherwise) listed as Special Concern.

Federally listed species are protected by the Endangered Species Act of 1973, as amended. The USFWS is the
federal agency responsible for listing and protecting nationally endangered and threatened species. As of February
2002, there are 27 plant species federally listed as Endangered or Threatened which occur in North Carolina. These
species are distributed throughout the state, in about half of North Carolina' s hundred counties. In addition, about a
hundred species are active candidates for listing.
These three agencies work cooperatively to ensure the continued survival of all of North Carolina' s rich flora.

LIST FORMAT. Species are grouped into five groups: Vascular Plants, Mosses, Liverworts, Hornworts, and
Lichens. They are listed alphabetically by scientific name within each group. The following information is
presented for each species on the list.
Scientific Name. Taxonomy and nomenclature of vascular plants (dicots, monocots, gymnosperms, ferns, and fern
allies) generally follow A.S. Weakley, L.E. Anderson, M.L. Hicks, and J.A. Kartesz' sA Checklist of the Vascular
Flora and Bryophytes of North Carolina (in prep.) and J.T. Kartesz’s A Synonymized Checklist and Atlas with
Biological Attributes for the Vascular Flora of the United States, Canada, and Greenland. First Edition. (In:
Kartesz, J.T., and C.A. Meacham. Synthesis of the North American Flora, Version 1.0. North Carolina Botanical
Garden, Chapel Hill, NC. Copyright c 1999). Scientific authorities for names have been omitted to save space, but
follow Weakley et al. (in prep.) and Kartesz (1999). Where this differs from the treatment in A.E. Radford, H.E.
Ahles, and C.R. Bell' sM anual of the Vascular Flora of the Carolinas (1968), the name used in that work is
indicated in brackets. In a small number of cases, other commonly used synonymy is also indicated. If the species
was not treated in Radford, Ahles, and Bell and cannot be identified using that manual, the notation "[not in RAB]"
follows the scientific name. If the species is treated in Radford, Ahles, and Bell, but was not indicated as occurring
in North Carolina, the notation "[not in NC in RAB]" follows the scientific name. Taxonomy and nomenclature of
nonvascular plants (mosses, liverworts, hornworts, and lichens) generally follow L.E. Anderson, H.A. Crum, and
W.R. Buck' sL ist of the Mosses of North America North of Mexico (Bryologist 93: 448-499 [1990]), L.E. Anderson' s

Common Name. A common name is provided for the convenience of the user. Common names for plants are not
standardized, and many plants have no entirely satisfactory common name.
North Carolina Status. Endangered, Threatened, and Special Concern species have legally protected status in North
Carolina through NC PCP. NC NHP maintains computer and map files on Endangered, Threatened, Candidate, and
Significantly Rare species; paper files are maintained on Watch List species.
STATUS
CODE
STATUS DEFINITION
E Endangered "Any species or higher taxon of plant whose continued existence as a viable
component of the State' s flora is determined to be in jeopardy" (GS 19B 106:
202.12). (Endangered species may not be removed from the wild except when a
permit is obtained for research, propagation, or rescue which will enhance the
survival of the species.)
T Threatened "Any resident species of plant which is likely to become an endangered species
within the foreseeable future throughout all or a significant portion of its range"
(GS 19B 106:202.12). (Regulations are the same as for Endangered species.)
SC Special
Concern
"Any species of plant in North Carolina which requires monitoring but which
may be collected and sold under regulations adopted under the provisions of [the
Plant Protection and Conservation Act]" (GS 19B 106:202.12). (Special
Concern species which are not also listed as Endangered or Threatened may be
collected from the wild and sold under specific regulations. Propagated material
only of Special Concern species which are also listed as Endangered or
Threatened may be traded or sold under specific regulations.)
SR Significantly
Rare
Species which are very rare in North Carolina, generally with 1-20 populations in
the state, generally substantially reduced in numbers by habitat destruction (and
sometimes also by direct exploitation or disease).
-L Limited The range of the species is limited to North Carolina and adjacent states
(endemic or near endemic). These are species which may have 20-50 populations
in North Carolina, but fewer than 50 populations rangewide. The preponderance
of their distribution is in North Carolina and their fate depends largely on
conservation here. Also included are some species with 20-100 populations in
North Carolina, if they also have only 50-100 populations rangewide and
declining.
-T Throughout These species are rare throughout their ranges (fewer than 100 populations
total)
4
-D Disjunct The species is disjunct to NC from a main range in a different part of the country
or world.
-P Peripheral The species is at the periphery of its range in NC. These species are generally
more common somewhere else in their ranges, occurring in North Carolina
peripherally to their main ranges, mostly in habitats which are unusual in North
Carolina.
-O Other The range of the species is sporadic or cannot be described by the other
Significantly Rare categories
W Watch List Any other species believed to be rare and of conservation concern in the state but
not warranting active monitoring at this time (see the Watch List section in the
Supplement for a more complete discussion).
P_ Proposed A species which has been formally proposed for listing as Endangered,
Threatened, or Special Concern, but has not yet completed the legally mandated
listing process.
United States Status is designated by the U.S. Fish and Wildlife Service. Federally listed Endangered and
Threatened species are protected under the provisions of the Endangered Species Act of 1973, as amended. Unless
otherwise noted, definitions are taken from the Federal Register, Vol. 55, No. 35, Septmeber 30, 1993 (50 CFR Part
17).
NOTE: In February 1996, the U.S. Fish and Wildlife Service revised its categories for the Candidate (=Status
Review) list.
􀀀 Taxa formerly considered as ‘Category 1' candidates for listing are now considered as ‘Candidate’.
􀀀 Taxa formerly considered as ‘Category 2' candidates are now no longer being maintained by the Service as
Candidate or Status Review taxa. The Service suggests that such taxa be considered as ‘Species of
Concern’ or ‘Species at Risk’, neither of which has official status. The NC NHP uses ‘(Federal) Species of
Concern’ in this document for those taxa formerly considered as Category 2.
􀀀 Taxa formerly considered as ‘Category 3' candidates are now no longer being maintained by the Service.
These were taxa: 1) for which the Service has persuasive evidence of extinction (Category 3A); 2) that do
not represent distinct entities meeting the Act’s Definition of ‘species’ (Category 3B); or 3) that have
proven to be more abundant or widespread, or not subject to any identifiable threat (Category 3C).
STATUS
CODE
STATUS DEFINITION
E Endangered A taxon "which is in danger of extinction throughout all or a significant
portion of its range" (Endangered Species Act, Section 3).
T Threatened A taxon "which is likely to become an endangered species within the
foreseeable future throughout all or a significant portion of its range
(Endangered Species Act, Section 3).
5
C Candidate "Taxa for which the [Fish and Wildlife] Service has on file enough
substantial information on biological vulnerability and threat(s) to support
proposals to list them as endangered or threatened. Proposed rules have not
yet been issued because this action is precluded at present by other listing
activity. Development and publication of proposed rules on these taxa are
anticipated. The Service encourages State and other Federal agencies as well
as other affected parties to give consideration to these taxa in environmental
planning.” (Federal Register, February 28, 1996). Taxa formerly considered
as ‘Category 1' are now considered as ‘Candidate’.
FSC (Federal) Species
of Concern
“... the Service is discontinuing the designation of Category 2 species as
candidates in this notice. The Service remains concerned about these
species but further biological research and field study are needed to resolve
the conservation status of these taxa. Many species of concern will be found
not to warrant listing, either because they are not threatened or endangered
or because they do not qualify as species under the definition in the
[Endangered Species] Act. Others may be found to be in greater danger of
extinction than some present candidate taxa. The Service is working with
the States and other private and public interests to assess their need for
protection under the Act. Such species are the pool from which future
candidates for listing will be drawn.” (Federal Register, February 28, 1996).
P_ Proposed "Taxa already proposed to be listed as "endangered or threatened. Taxa
formally proposed as endangered or threatened receive some legal
protection. Species listed as proposed candidates are species which are in
the process of being added to the federal candidate list.
North Carolina Rank. North Carolina ranks are based on The Nature Conservancy' s (TNC) system of measuring
rarity and threat status. This system is now widely used by other agencies and organizations, as the best available
scientific and objective assessment of a species' rarity at the state level.
RANK NUMBER OF EXTANT
POPULATIONS
DESCRIPTION
S1 1-5 Critically imperiled in North Carolina because of extreme rarity or because of
some factor(s) making it especially vulnerable to extirpation (local extinction)
from the state.
S2 6-20 Imperiled in North Carolina because of rarity or because of some factor(s)
making it very vulnerable to extirpation from the state.
S3 21-100 Rare or uncommon in North Carolina.
S4 100-1000 Apparently secure in North Carolina, with many occurrences.
S5 1000+ Demonstrably secure in North Carolina.
SA -- Accidental in state.
SH 0? Of historical occurrence in North Carolina, perhaps not having been verified in
the past 20 years, and suspected to be still extant.
6
SR -- Reported from North Carolina, but without persuasive documentation which
would provide a basis for either accepting or rejecting the report.
SX 0 Apparently extirpated from North Carolina.
SU -- Possibly in peril in North Carolina but status uncertain; need more information.
S? -- Unranked, or rank uncertain.
SE? -- Introduced in part of the state, but believed native in other parts of the state
A rank involving two numbers indicates uncertainty of rank. For instance, a S2S3 rank indicates that the species may
be a S2 or a S3, but that existing data do not allow that determination to be made.
Global Rank. Similar to North Carolina ranks, global ranks are assigned by a consensus of scientific experts, the
various natural heritage programs and TNC. They apply to the status of a species throughout its range, and are based
on data on the species' status rangewide. This system is now widely used by other agencies and organizations, as the
best available scientific and objective assessment of a species' rarity throughout its range.
RANK NUMBER OF EXTANT
POPULATIONS
DESCRIPTION
G1 1-5 Critically imperiled globally because of extreme rarity or because of some
factor(s) making it especially vulnerable to extinction.
G2 6-20 Imperiled globally because of rarity or because of some factor(s) making it
very vulnerable to extinction throughout its range.
G3 21-100 Either very rare and local throughout its range or found locally (even
abundantly at some of its locations) in a restricted range (e.g., a single
physiographic region) or because of other factors making it vulnerable to
extinction throughout its range.
G4 100-1000 Apparently secure globally, though it may be quite rare in parts of its
range, especially at the periphery.
G5 1000+ Demonstrably secure globally, though it may be quite rare in parts of its
range, especially at the periphery.
GH 0? Of historical occurrence throughout its range, i.e., formerly part of the
established biota, with the expectation that it might be rediscovered.
GX 0 Believed to be extinct throughout its range (e.g., passenger pigeon) with
virtually no likelihood that it will be rediscovered.
GU -- Possibly in peril range-wide, but status uncertain; need more information.
G? -- Unranked, or rank uncertain.
G_Q -- Questionable taxonomic assignment.
T_ -- The rank of a subspecies or variety. As an example, G4T1 would apply to
a subspecies of a species with an overall rank of G4, but the subspecies
warranting a rank of G1.
7
A rank involving two numbers indicates uncertainty of rank. For instance, a G2G3 rank indicates that the species
may be a G2 or a G3, but that existing data do not allow that determination to be made.
Physiographic Province. The provinces in which the species is known to occur are indicated. This should not be
regarded as the only province(s) of the state in which the species could occur; our knowledge of the flora of North
Carolina is still very imperfect. The provinces are abbreviated as follows:
M Mountains (Blue Ridge) All parts of North Carolina west of the foot of the Blue Ridge Escarpment.
P Piedmont All parts of North Carolina east of the foot of the Blue Ridge Escarpment and
west of the Fall Line, including outlying "foothill" ranges, such as the Brushy,
Uwharrie, and Sauratown Mountains. This province is shallowly underlain by
crystalline metamorphic, igneous, or (rarely) consolidated sedimentary rocks.
S Sandhills Portions of Cumberland, Harnett, Hoke, Lee, Moore, Richmond, Scotland, and
Montgomery counties consisting mostly of deep aeolian sands of the Middendorf
and Pinehurst formations (Cretaceous to Tertiary age). The Sandhills are really
part of the coastal plain but are here distinguished because of their distinctive
geomorphology and vegetation. Areas somewhat resembling the Sandhills region
but occurring in other parts of the state (such as Carolina bay rims and aeolian or
beach ridge deposits in the outer Coastal Plain) are considered part of the Coastal
Plain Province.
C Coastal Plain All parts of North Carolina east of the fall line, excluding the Sandhills, generally
consisting of unconsolidated sands, silts, clays, and peats, though rarely
shallowly underlain by consolidated coquina limestone ("marl").
T Tidewater That part of the state associated with tidal water such as the ocean and barrier
islands, sounds, estuaries and mainland brackish or salt marshes.
Habitat. The known habitats are described; as with provinces, these should not be regarded as the only possible
habitats of the species in the state.
Counties of known occurrence. Following the description of habitats is a listing of the known counties of
occurrence. Counties with historic populations (not seen since 1979) are marked with an asterisk (*) and counties
with obscure or undateable records are marked with a cross (+). If there is some question as to the validity of the
county report, it is marked with a question mark (?). The botanical exploration of North Carolina is far from
complete, and many additional county records will be found, generally (but not always) in proximity to counties
listed.
