"2 "TT EvERARDIA ANGUsTA, N. E. Brown, sp. n. Folia linearia, acuta, laxe pilosa. Culmi 
basi vaginati, aphylli, valde compressi, leviter concavo-convexi, parce pilosi vel fere 
glabri. Panieula elongata, linearia, stricta, ramis gracilibus erectis 1- (rare 2-)spicu- 
latis in axillis vaginorum aggregatis. Spiculee mascule lanceolate, glumis 5-7 
coraceis oblongis acutis mucronatis brunneis sterilibus et glumis 4-6 membranaceis 
oblongis obtusis fertilibus instructs; stamina sub quaque gluma 6-12. Spicule 
foemineze omnes ad apicem paniculi dispositee, glumis 5 oblongo-lanceolatis acutis 
mucronatis ovarium solitarium stipitatum circumdatis: stigmata 3, dense villosa ; 
pili hypogyni copiosi. | 
Leaves in tufts of 3-6, distinct from the flowering culms, 8-12 in. long, 14-13 lin. 
| broad, linear, aeute, often folded, but when expanded channelled down the face, with an 
acute ridge on each side of the channel, flat on the back, thinly pilose, usually slightly 
recurving. Flowering culms 14-18 in. high, including the panicle, 1-$ lin. broad, 
flattened, slightly concave on one side, convex on the other, sparingly pilose or nearly 
glabrous, produced on distinct leafless shoots, embraced by a long glabrous leafless sheath 
at the base. Panicle 7-12 in. long, strictly erect, linear, composed of 4-5 distant tufts 
of erect, simple or once umbellately divided, filiform branchlets, clustered in the axils of 
close-fitting brown sheaths 3—2 in. long, which have spreading leafy points 4-1 in. long. 
Spikelets solitary or very rarely 2 at the end of the branchlets, light brown. Male 
spikelets 3-4 lin. long, 1-14 lin. thick, lanceolate, with 5-7 coriaceous, oblong, acute, 
mucronate, brown empty glumes, thinly and minutely pubescent on the back, and 4—6 
membranous, oblong, obtuse, fertile glumes; stamens 6-12 under each glume; anthers 
) 2 lin: long, linear, tipped with a minute tuft of stiff hairs. Female spikelets all at 
the apex of the panicle, more slender than the males, 3 lin. long, about 3 lin. thick, with 
about 5 oblong-lanceolate, acute, mucronate, minutely ciliate glumes surrounding the 
solitary pubescent ovary; stigmas 3, densely villose ; hypogynous hairs copious. 
Summit of Mount Roraima, 8600 ft., McConnell & Quelch, 676. 
This species is easily distinguished from the following by its very much narrower 
leaves and less floriferous panicles.
