76 BEPOfiT OX TWO BOTANICAL COLLECTIONS FROM 



The spikelets on the specimens seen are imperfect, most of them consisting of empty 

 bracts only, and none that I have examined contain a perfect ovary. 



Chusqtjea linearis, N. E. Brown, sp. n. Culmi graeiles, internodiis f— 2j poll, longis, 



ramulis brevibus ad nodos aggregatis. Folia (5-10 lin. longa, 1-1-g lin. lata, lanceo- 



lata, acutissima, glalmx, secus unum marginem minute scaberula; vaginas striataa, 



pubescentes, Mgula brevi subtruncati. Racemi ad nodos aggregati, lineares, spiculis 



3-0, unifloris. Glumae inferiores 4 vacua', glunia infima minima, sequentes majores 



pubescentes ; glunia florens convoluta, obtusa, apicem tantum puhescens, 7-8- 



nervis. Palea oblongo-ovata, obtusa, convoluta, glabra, apice ciliata, 4-nervis 



Stems slender, terete, glabrous, with internodes §-2| in. long, concealed by the striated 



sheaths, hearing at the nodes clusters of 4-10 simple leafy or flowering branches 1^-3 in. 



long. Leaves distichous, those on the branches 1^-2 lin. distant, 6-10 lin. long, 



1-1^ lin. broad, lanceolate, tapering to a very acute mucronate point, abruptly narrowed 



into a very short petiole at the base, glabrous, minutely ciliate-scabrid along one 



margin, striate beneath from the numerous closely placed prominent nerves; sheaths 



striate, pubescent ; ligule short, subtruncate, no bristles. Racemes linear, with 3-6 



pedicellate, adpressed, 1-flowered spikelets, or the terminal one with 14-15 spikelets. 



Outer 4 glumes empty; the lowest J-f lin. long, broadly oblong, obtuse, 1 -nerved ; the 



second lj-lf lin. long, oblong, obtuse, with or without a short awn, 1-nerved ; the two others 



subequal, 2^-2| lin. long, oblong-lanceolate, acute, very concave, 5-6-nerved, all more or 



less pubescent on the back and ciliate, at least at the apex. Flowering glume 2f lin. 



long, ovate-lanceolate, obtuse, convolute, pubescent and ciliate at the apex only, with 



7-8 slender nerves. Pale 2 lin. long, oblong-ovate, convolute, obtuse and ciliate at the 



apex, membranous, with I slender nerves. Lodieules 3. narrowly oblong, obtuse, ciliate 



at the apex, §-f lin. long. Stamens 3 ;" anthers 1 lin. long, linear. Ovary narrowly 



ovoid, glabrous ; styles 2, narrowly plumose nearly to the base. 



Summit of Mount Eoraima, 8600 ft., McCormell §f Quelch, 677. 



Allied to C. dbietifolia, Griseb., but among other characters is easily distinguished by 

 its linear racemes.
