Family:Cyperaceae
Description:Latin Diagnosis - Ab omnibus speciebus Everardiae caudicibus et vaginis basilaribus copiose lanatis valde distat. Planta dioeca. Caudices breves divisi reliquis vaginarum mortuorum et lanis albo-flavescentibus copiosis crasse vestiti; radicibus crassiusculis. Folia anguste linearia ad 30 cm longa 2 mm lata plus minus revoluta margine utrinque albopilosa apice gradatim angustata acuta; vaginae dense lanata. Culmi laterales ex axilla foliorum orti intra folia absconditi 20-23 cm alti graciles laeviusculi infra medium ad apicem spiculigeri. Inflorescentia paniculato-fascicularis interrupta 3-5-nodosa; paniculae partiales 3-5 paniculato-crymbosae, ramis gracilibus 5-9-nis valde inaequalibus fasciculatae, ramis ramulisque albo-pubescentibus; braeteae inferiores inflorescentiam superantes. Spiculae masculae oblongae usque oblongo-ellipticae circiter 2 mm longae; glumae imbricatae ovatae vel ovatooblongae membranaceae fulvae inferiores 1 ad 3 vacuae caeterae staminiferae apice breviter acutae, paucinervosae margine superne ciliatae; stamina 2. Spiculae foemineae ellipticae 1-florae 2 m m longae; glumae ellipticae vel ovatooblongae margine pilis longiusculis ciliatae. Fructificationes (immaturae) ovatoellipticae trigonae spice brevirostratae, stigmatibus 3, stylo brevissimo fere nullo.

Distribution and Ecology - Distribution. Known only by the cited specimens.

Discussion:This striking species because of its lanate caudex does not resemble any other species of the genus. Lanate caudices of this kind are often seen in the section Imierhitae of Lagenocarpus, but the lateral flowering culms arising from the axils of the lower leaves of the caudex demonstrate this to be a species of Everardia. Mr. Garcia-Barriga, the collector of the type specimen, kindly sent us a photograph and ecological note of the type locality. The note shows that E. lanata grows on bare escarpments. This habitat is characteristic of Everardia but not of Lagenocarpus. B y its fructification with a short conical beak, the nature of cilia of leaves, and by the dioecism, this species is assigned to the section Pseudo-everardia.
