Spikes 3 or 4, upper spikes crowed, the lowest one rarely exserted at base of culms; terminal one staminate, clavate-cylindrical, 2 – 2.5 cm long, ca. 4 mm wide, densely flowered, nearly sessile; lateral spikes androgynous, 1.5 – 2.3 cm long, slightly densely flowered, with 4 – 9 staminate flowers at apex, with peduncles enclosed in bract sheaths. Staminate scales oblanceolate-elliptic, 7.5 – 8 mm long, acute at apex, yellowish brown at margins, brown costa 1 - veined on dorsal surface. Pistillate scales ovate, 5 – 5.5 mm long, acuminate at apex, pale yellowish brown at margins, green costa 3 - veined on dorsal surface, exserting into a short awn at apex. Perigynia longer than pistillate scales, 7.5 – 8 mm long, obovoid or ellipsoid, trigonous, membranous, greenish yellow, nearly glabrous, distinctly veined, shortly stipitate at base, contracted into a ca. 3 mm long beak at apex; orifice shortly 2 - lobed with long teeth, sparsely pilose at margins.

F37687BA25196E18FF177C08FC962F90.taxon	distribution	Distribution & Habitat: — This new species is known only from Huangshan Mountain, Anhui Province, eastern China (Figure 3). It is endemic to China, with an apparently narrow geographic distribution. It grows on the cliffs around Yupinglou at an elevation of ca. 1400 m. Phenology: — Flowers and fruits of Carex huangshanica were collected in late May.	en	Chen, Wei-Jie, Jin, Xiao-Feng (2015): Carex huangshanica (sect.

F37687BA25196E18FF177C08FC962F90.taxon	etymology	Etymology: — The epithet “ Huangshan ” refers to the type locality of the collection. Additional collections (paratypes): — CHINA. Anhui Province: Huangshan, Huangshan Mount., Yupinglou, 118 º 10 ’ 16.17 ’ E, 30 º 07 ’ 27.61 ’’ N, on cliff, elevation 1400 m, 26 May 2014, W. J. Chen 424 B, 425 (HTC!). IUCN Red List Category: — From field observation, the population of Carex huangshanica comprises ca. 50 caespitose individuals and covers an area of ca. 50 m 2. Referring to IUCN Category and Criteria (version 3.1) in 2001, it is a vulnerable species (VU), and there is a need for its conservation. Similar species: — Carex huangshanica is similar to Carex longirostrata. in having perigynia gradually contracted into a long beak at apex, orifice 2 - lobed with long teeth, achenes not constricted at middle of angles, abruptly contracted into a beak at apex, but differs in having upper spikes aggregated, pistillate scales shortly awned at apex, perigynia nearly glabrous, and achenes ovoid. In Carex longirostrata, all spikes are remote, pistillate scales long awned at apex, perigynia sparsely pubescent and achenes ellipsoid-ovoid to broadly obovoid (Figure 4). Characters distinguishing the new species from C. longirostrata are detailed in Table 1.	en	Chen, Wei-Jie, Jin, Xiao-Feng (2015): Carex huangshanica (sect.
