Carex

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. Of the non-native taxa, the two species of Asiatic sand sedge, included here in Carex sect. Macrocephalae, are considered to be potentially invasive. 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). This page was later re-organized somewhat based on the intermediate framework recommended by the Global Carex Group (GCG)(2021). Where practicable, the traditional (FNA) sections were left intact within any larger clades into which their members were placed by GCG. New York Natural Heritage Program Rare Plant Status Lists.

III. Carex subg. Euthyceras Peterm., Deutschl. Fl. 602. 1849. Type species: Carex microglochin Wahlenb.

Subg. Euthyceras > Rara Clade >> sect. Leptocephalae

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. The traditional Carex section Leptocephalae contains the single species Carex leptalea which is found in North America and the Caribbean Basin. iNaturalist currently treats the Rara Clade as Complex Carex leptalea (Carex Rara Clade).

Subg. Euthyceras > Capitata Clade

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. The traditional (FNA) Carex section Leucoglochin contains about five species worldwide, with Carex microglochin and Carex pauciflora found in North America. The Global Carex Group (2021) placed Carex microglochin with sect. Capituligerae and a few other species in subg. Euthyceras clade Capitata (III.B.3) iNaturalist currently treats subg. Euthyceras clade Capitata (III.B.2) as Complex Carex capitata (Carex capitata Clade). 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. Vignea

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.

Subg. Vignea > Echinata Clade >> sect. Stellulatae

Carex echinata V.C.1. Echinata Clade contains the traditional section Stellulatae (11/11) along with Eurasian species C. elongata and C. foetida. The traditional Carex (FNA) section Stellulatae contains about 15 taxa worldwide, eight of which are found in North America. 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. iNaturalist places this group in Complex Carex elongata (Carex Echinata Clade) as of 2/12/2024.

Subg. Vignea > sect. Phaestoglochin

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). 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.

Hymenochlaenae species globally, including Carex cherokeensis, C. fokienensis, C. hubbardii, C. iynx, C. longebrachiata, C. metallica, C. obispoensis, C. tunimanensis. The traditional (FNA) sect. Hymenochlaenae contains 20 North American Carex species. Of these, only the southeastern Carex cherokeensis and endemic Californian Carex obispoensis remain in the newly delineated sect. Hymenochlaenae. Most of the rest are now in the Castanea Clade above. A single casual observation of cultivated and labeled Carex cherokeensis (Cherokee Sedge) at the Brooklyn Botanic Garden, New York in 2023 has been posted to iNaturalist The nearest research-grade iNaturalist observation appears to be in Kentucky.

C. concinnoides is remarkable for being the only known sedge with 4 stigmas. The traditional (FNA) sect. Clandestinae contains 4 North American Carex species (C. concinna, C. concinnoides, C. pedunculata, and C. richardsonii). Of these, C. richardsonii appears to be extirpated from New York State, and C. pedunculata was moved to sect. Pictae.

Subg. Carex > sect. Acrocystis

Carex communis VI.W.3. Carex sect. Acrocystis Dumort., Fl. Belg. 147. 1827. Contains about 39 of the 51 species globally of traditional Carex sect. Acrocystis. The traditional (FNA) Carex section Acrocystis contains about 35 (51) species worldwide, 20 of which are found in North America North of Mexico, including about a dozen loosely- or densely-cespitose sedge species that are found in New York.. Characteristics include narrow leaves, basal leaves with red bases, and beaked perigynia in short spikelets. Groups within Carex sect. Acrocystis used here are based on Roalson & Friar (2004). This section contains some of the smallest sedges in the Northeast. D.B. Poindexter (2019) recommended replacing the Carex section name Acrocystis Dumort. (1827) with Sphaeridiophorae Drejer ex L.H.Bailey (1885), using Carex pensylvanica Lam. (1792) as its lectotype instead of Carex montana L. (1755), which was also the lectotype of sect. Montanae (Carey) Christ (1885). Carex montana was explicitly excluded from Poindexter's treatment of sect.

Subg. Carex > sect. Acrocystis >> Eastern North America clade

Roalson & Friar (2004) grouped sect. Acrocystis into eastern and western North American groups. The first Eastern North America Clade (ENAC1) contains the C. pensylvanica complex, the C. nigromarginata complex, and the C. umbellata complex.

Subg. Carex > sect. Acrocystis >> ENA Pensylvanica Species Complex

Carex pensylvanica The Pensylvanica species complex of Carex sect. Acrocystis (sensu Crins & Ball 1983) contained C. lucorum, C. pensylvanica and the western C. inops (sspp. inops & heliophila). Poindexter (2019) determined that western species C. inops and C. heliophila are not closely related to C. pensylvanica and placed them in the a southwestern North America clade.

Subg. Carex > sect. Acrocystis >> ENA Umbellata Species Complex

Carex umbellata The Umbellata species complex traditionally includes Carex umbellata, C. tonsa var. rugosperma, and C. tonsa var. tonsa. In part because C. rugosperma and C. umbellata have been found to form a sister clade to C. microrhyncha and another newly studied species in this complex, the species rank is probably justifiable for each of these taxa. These sedges are very small, with obscure culms.

Subg. Carex > sect. Acrocystis >> Western America Ancestral Clade

Carex communis The second Eastern North America Clade (ENAC2, containing C. communis & C. peckii) was found to have been embedded in the second Western North America Clade (WNAC2). Carex deflexa is one of 4 members of Acrocystis (including C. rossii, C. tonsa, and C. umbellata) that have pistillate spikes at the base. D.B. Poindexter (2019) found weak support for clade (WA-AC) containing C. communis + C. deflexa as sister to C. peckii in the Western America Clade
