![]() Cypringlea evadens, previamente considerada como variedad de C. Key words: Cyperaceae, Cypringlea, endemism, Mexico, Scirpus.Ĭypringlea (Cyperaceae) es un género segregado de Scirpus, endémico de México, con tres especies. evadens is newly recorded for Guerrero and Oaxaca. coahuilensis, previously known only from the type collection in Coahuila, is recorded also from Nuevo León, and C. Cypringlea analecta is newly recorded for Nuevo León, Tamaulipas and Querétaro, C. A key to distinguish the species, as well as descriptions and data on distribution and habitat are given. It differs in the degree of inflorescence compounding, proportion of spikes that are peduncled, total number of spikes, as well as leaf width and the proportionate length of inflorescence bracts. analecta, is raised here to the specific level. Cypringlea evadens, previously treated as a variety or under synonymy of C. en enero de 2007Ĭypringlea (Cyperaceae), a Mexican endemic genus segregated from Scirpus, includes three species.

Revista de Cypringlea (Cyperaceae), nueva combinación y cambio en el nivel taxonómicoĪnton A. Chromosome number: not known.Cypringlea (Cyperaceae) revisited, a new combination and status 4 mm long, 2.5 mm wide, flattened to thickened reniform, reddish brown, the surfaces minutely pitted, in mature fruits the lateral testal cell walls exposed and the seed prominently silky, the testal cells rectangular to slightly sinuate. 1 mm in diameter at the base, somewhat woody, deflexed or spreading. Fruit a globose to slightly ellipsoid berry, to 1.5 cm in diameter, bright red when ripe, the pericarp thin and shiny, glabrous fruiting pedicels 1–1.5 cm, ca. Ovary glabrous style 6–8 mm long, glabrous stigma capitate to somewhat clavate, the surface minutely papillose. 1 mm long, glabrous anthers 3.5–4 mm long, 1–1.5 mm wide, ellipsoid, loosely connivent, poricidal at the tips the pores lengthening to slits with age. Filament tube minute, the free portion of the filaments ca. 0.3 cm wide, reflexed at anthesis, the midvein often tinged purple, glabrous to sparsely pubescent abaxially especially along the distal margins and tips, glabrous adaxially. Corolla 1.5–1.9 cm in diameter, white or tinged with purple, often with a shiny green or greenish white eye, stellate, lobed nearly to the base, the lobes 0.8–0.9 mm long, ca. ![]() Calyx tube 1–1.5 mm long, conical, the lobes 1.5–2 mm long, triangular with the tips often long-acuminate, often purplish tinged, glabrous to sparsely pubescent abaxially, densely papillate adaxially, pubescent with simple trichomes to 0.2 mm on internal surface of tips. Buds when young globose, later ellipsoid, the corolla strongly exserted from the calyx tube before anthesis. 1 mm in diameter at the apex, slender, sometimes tinged purple, glabrous to sparsely pubescent with simple uniseriate white trichomes, articulated at the base from a short sleeve 0.5–1 mm deep pedicel scars irregularly spaced 1–4 mm apart. Inflorescences terminal or lateral, 1–3 cm long, usually simple, very occasionally furcate, with 3–6 flowers, glabrous to pubescent like the stems, the pubescence like that of the rest of the plant peduncle 0.3–1 cm long pedicels 0.6–1.2 cm long, ca. Leaves simple to basally lobed and hastate, (1.1-)1.8–5(+) cm long, (0.3-)1–3.5 cm wide, deltate to hastate, triangular in outline, sometimes linear, slightly fleshy, the upper and lower surfaces pubescent with simple uniseriate trichomes along the margins and on the veins to uniformly pubescent on the veins and lamina, the trichomes to 0.5 mm long, white primary veins 3–5 pairs, only just visible in dried material, sometimes slightly impressed above base abruptly truncate to hastate with 2 basal lobes to 1 cm long, these rounded at the tip margins entire to basally lobed apex acute to acuminate, the tip sometimes rounded petioles 0.3–1.2 cm long, glabrous but with a line of simple trichomes adaxially, apparently only sometimes twining. Bark of older stems pale greenish yellow. Stems somewhat angled, glabrous to pubescent with weak simple uniseriate trichomes to 0.5 mm long, these usually ascending and pointing to the distal part of the stems new growth sparsely to densely pubescent with simple uniseriate trichomes to 0.5 mm long, but usually shorter. Semi-woody vine or scrambler with an enlarged woody base, to 2 m long, occasionally an erect subshrub to 0.5 m tall.
