New York Carex cladogram ⇗

Carex edit

The genus Carex is represented by more than 200 species in New York. Of these, all but about a dozen species are native to New York State.[1] Of the non-native taxa, the two species of Asiatic sand sedge, included here in Carex sect. Macrocephalae, are considered to be potentially invasive.[2] Only one of these, Carex kobomugi, has been reported in New York (a single population in 2013), but both have been reported in nearby states.

Here, the genus was previously organized by sections, using the modified version of Kenneth Kent Mackenzie’s system used in the Flora of North America (FNA).[3][4]

This page was later re-organized somewhat based on the intermediate framework recommended by the Global Carex Group (GCG)(2021).[5]

Where practicable, the traditional (FNA) sections were left intact within any larger clades into which their members were placed by GCG.

Type species: Carex microglochin Wahlenb.[2]


Subg. Euthyceras > Rara Clade >> sect. Leptocephalae edit

 
Carex leptalea
III.B.1. Rara Clade contains traditional sections Rarae (23/23), Rhizopodae (3/3), Leptocephalae (1/1). Of the 27 or so species in the resulting clade, only Carex leptalea is native to North America. The rest are Asian or Australasian species.[1]

The traditional Carex section Leptocephalae contains the single species Carex leptalea which is found in North America and the Caribbean Basin.[2]

iNaturalist currently treats the Rara Clade as Complex Carex leptalea (Carex Rara Clade).[3]

Subg. Euthyceras > Capitata Clade edit

 
Carex microglochin
III.B.2. Capitata Clade contains all or parts of traditional sections Capituligerae (6/6), Leucoglochin (1/5), Petraeae (2/3), Nardinae (1/1), Obtusatae (1/1).

The traditional (FNA) Carex section Capituligerae contains about six species worldwide, with Carex arctogena and Carex capitata found in North America.[1]

The traditional (FNA) Carex section Leucoglochin contains about five species worldwide, with Carex microglochin and Carex pauciflora found in North America.[2]

The Global Carex Group (2021) placed Carex microglochin with sect. Capituligerae and a few other species in subg. Euthyceras clade Capitata (III.B.3)[3]

iNaturalist currently treats subg. Euthyceras clade Capitata (III.B.2) as Complex Carex capitata (Carex capitata Clade).[4]

None of the sedges in this clade have been reported in New York, but a few have been reported from New England and eastern Canada. They are included here as placeholder representatives of the calde.

Carex subg. Uncinia edit

IV. Carex subg. Uncinia (Pers.) Peterm., Deutschl. Fl. 602. 1849.[1]

Type species: Uncinia australis Persoon, nom. illeg. (Carex uncinata L.f.) (designated by Pfeiffer, 1874–1875, Nomenclator Botanicus 2 (2): 1529).[2]


Subg. Uncinia > sect. Phyllostachyae edit

 
Carex backii
IV.D. Carex sect. Phyllostachyae Tuck. ex Kük., in H.G.A.Engler, Pflanzenr. 20[IV,38]: 642. 1909.

Sect. Phyllostachyae contains all of traditional (FNA) sect. Phyllostachyae (10/10). The Global Carex Group found strong support for this section being monophyletic.[1]

The traditional (FNA) Carex section Phyllostachyae contains about ten North American species,[2] three of which have been found in New York State.

iNaturalist currently treats subg. Uncinia sect. Phyllostachyae (IV.D) as Section Phyllostachyae (Carex Sect. Phyllostachyae).[3]

Carex subg. Vignea edit

V. Carex subg. Vignea (P.Beauv. ex T.Lestib.) Heer, Mitth. in Geb. Theor. Erdk. 1: 426. 1836.

Most of the sedges of subgenus Vignea have dense spike-like inflorescences with sessile bisexual spikes. Their flowers are almost always distigmatic.[1]


Subg. Vignea > Echinata Clade >> sect. Stellulatae edit

 
Carex echinata
V.C.1. Echinata Clade contains the traditional section Stellulatae (11/11) along with Eurasian species C. elongata and C. foetida.[1]

The traditional Carex (FNA) section Stellulatae contains about 15 taxa worldwide, eight of which are found in North America.[2]

Sedges in section Stellulatae are found in wetlands and have flattened, beaked perigynia with sharp edges that often point outward at maturity, creating star-like pattern.[3]

iNaturalist places this group in Complex Carex elongata (Carex Echinata Clade) as of 2/12/2024.

Subg. Vignea > sect. Phaestoglochin edit

 
Carex spicata
V.E.1. Carex sect. Phaestoglochin Dumort., Fl. Belg. 146. 1827.

Contains traditional sections Phaestoglochin (15/38), Vulpinae (2/13), and Echinochloomorphae (1/1). Consists primarily of Eastern Hemisphere species of traditional sect. Phaestoglochin, characterized by short rhizomes, inflorescences spicate (rarely distally branched), spikes androgynous, and perigynia wingless.

The Global Carex Group moved the New York sedges of traditional sect. Phaestoglochin into the three separate clades, leaving the non-native C. spicata as the only member reported in New York. The other members of this traditional section were moved to the Annectens Clade (V.E.2) and Rosea Clade (V.G.5). [1]

The traditional Carex section Phaestoglochin contained about 38 species worldwide, 25 of which are found in North America North of Mexico. Sedges of traditional section Phaestoglochin were characterized as upland species with compressed, sharp-edged oval perigynia, with male flowers appearing at the top of the spikelets.[2]

V.E.2. Annectens Clade contains 6 of the 16 traditional sect. Divisae species worldwide, including Carex praegracilis, the only New York species of sect. Divisae.[1]

The traditional (FNA) Carex section Divisae contains about 14 (16) species worldwide, 6 of which are found in North America North of Mexico. All of these are native to western North America, but Carex praegracilis has been spreading eastward along highways treated with road salt and is known to naturalize in New York.[2]

Subg. Vignea > sect. Physoglochin edit

 
Carex alascana
V.E.4. Carex sect. Physoglochin Dumort., Fl. Belg. 145. 1827.

Contains all 5 of the traditional sect. Physoglochin species globally, including New York's Carex alascana (syn. Carex gynocrates var. substaminata Peck)[1]

The traditional (FNA) Carex section Physoglochin contains 4-6 (5) species worldwide, 2 of which (C. gynocrates and C. parallela) are found in North America North of Mexico.[2] Of these, only Carex gynocrates (northern bog sedge) has been found in New York State, where it is listed as Endangered.

POWO (2023) treats Carex gynocrates Wormsk. ex Drejer as a synonym of Carex nardina (Hornem.) Fr.[3] (which is in subg. Euthyceras above.), but Carex gynocrates var substaminata Peck as a synonym of Carex alascana.[4] See discussion of name change at iNaturalist.

Carex kobomugi Ohwi at Futtsu city, Chiba Japan
V.G.3. Carex sect. Macrocephalae Kük., in H.G.A.Engler, Pflanzenr. 20[IV,38]: 186. 1909.

Contains both species (Carex kobomugi and C. macrocephala) of traditional section Macrocephalae.[1]

The traditional (FNA) Carex section Macrocephalae contains 2 species worldwide, both of which are found in North America North of Mexico.[2]

Although neither of these Carex sect. Macrocephalae species are listed as naturalized in New York, Carex kobomugi was found in the Great Kills and Miller Field areas of Gateway National Recreation Area on Staten Island on Oct. 31, 2013.[3]

Carex macrocephala has been reported on the coastal dunes of New Jersey, where Carex kobomugi is already common.[4]

Carex kobomugi has also been found on sandy beaches in Rhode Island and in Massachusetts, where it has been listed as prohibited.[5]

Subg. Vignea > Rosea Clade edit

 
Carex rosea
V.G.5. Rosea Clade contains 6 of the 38 species of traditional section Phaestoglochin.

The Global Carex Group (2021) divided the New York sedges of sect. Phaestoglochin into the three separate clades within subg. Vignea. The five eastern North American species C. appalachica, C. radiata, C. retroflexa, C. rosea, C. texensis were placed in Rosea Clade (V.G.5). The remainder were placed in sect. Phaestoglochin (V.E.1) and Annectens Clade (V.E.2). [1]

The traditional Carex section Phaestoglochin contains about 27 (38) species worldwide, 25 of which are found in North America North of Mexico.[2]

Sedges of section Phaestoglochin are upland species with compressed, sharp-edged oval perigynia. Male flowers appear at the top of the spikelets.

Subg. Carex > sect. Paniceae edit

VI.E.4. Carex sect. Paniceae G.Don, in J.C.Loudon, Hort. Brit. 376. 1830.

Most of the species of the three nested traditional sections Bicolores (4/4), Paniceae s.s. (24/26), and Laxiflorae (17/17) were combined into a larger sect. Paniceae. Although sect. Bicolores has been found to be monophyletic, it is nested in sect. Paniceae s.s., which is nested in sect. Laxiflorae.[1]


Subg. Carex > sect. Paniceae >> sect. Bicolores edit

 
Carex aurea
VI.E.4. Carex sect. Paniceae contains all 4 species of traditional sect. Bicolores globally.[1]

The traditional (FNA) Carex section Bicolores contains 4 species worldwide, all of which (C. aurea, C. bicolor, C. garberi, C. hassei) are found in North America, but only C. aurea and C. garberi are found in New York.[2]

Traditional sect. Bicolores contains two species that are found in New York State. The parigynia of C. aurea (golden-fruited sedge) are nearly spherical and turn bright orange when mature, while the those of the endangered C. garberi (elk sedge) turn glaucous white with age.[3]

Carex pedunculata
VI.G. Carex sect. Pictae Kük., in H.G.A.Engler, Pflanzenr. 20[IV,38]: 82. 1909.

Combines globally both traditional sect. Pictae species (C. baltzellii & C. picta) with 2 of the 46 traditional sect. Clandestinae species (C. pedunculata & C. erythrobasis).[1]

The traditional (FNA) Carex section Pictae contains 2 species worldwide (C. baltzellii, C. picta), both of which are found in North America North of Mexico, but neither has been found to naturalize in New York.[2]

The traditional (FNA) Carex section Clandestinae contains about 20 (46) species worldwide, 4 of which are found in North America North of Mexico. Of these, only Carex pedunculata is known in New York.[3]

Subg. Carex > Hirta Clade edit

VI.H.1. Hirta Clade contains all or parts of traditional sections Carex (16/18), Lupulinae (6/6), Paludosae (26/33), Squarrosae (2/4), and Vesicariae (49/49). These traditional sections are thought to represent largely monophyletic subclades. They share a number of morphological and habitat similarities and hybridize more readily than most other Carex groups.[1]

Subg. Carex > Hirta Clade >> sect. Paludosae edit

 
Carex lacustris
VI.H.1. Hirta Clade includes 26 of the 33 species globally of traditional sect. Paludosae.

New York species of traditional sect. Paludosae were distributed as follows:[1]

  • VI.H.1. Hirta Clade  : C. houghtoniana, C. hyalinolepis, C. lacustris, C. lasiocarpa, C. pellita, C. striata
  • VI.M.2. sect. Paludosae : C. acutiformis
  • VI.M.3. Vestita Clade  : C. vestita

The traditional (FNA) Carex section Paludosae contains about 35 (33) species worldwide, 14 of which are found in North America North of Mexico.[2]
