74 REPORT ON TWO BOTANICAL COLLECTIONS FROM 
subglauci, bivaginati, vagina inferiore foliosa. Panicula 2-3 poll. longa, oblonga, 
multiflora. Spicule ellipsoidez, 1-2-flore. Glum 3 inferiores vacuz, glabra, 
brunne:e vel atro-fusce ; gluma infima parva ; secunda et tertia subequales elliptice, 
obtuse, profunde concave 6-7-nerves. Gluma florens elliptica, obtusa, profunde 
concava, lzevis, 5-nervis, glabra, albida. Palea elliptica, obtusa, concava, 2-nervis, 
glabra, albida. 
Leaves, excluding the sheaths, 6-9 in. long, 25-3 lin. broad, linear, tapering to a very 
acute subpungent point, with involute margins, rigid, erect, greyish-glaucous, striate, 
more or less densely pilose on the upper side at the base, and densely villose-tomentose 
at the very base of the sheaths ; ligule none. Culms 10-13 in. long, straight, striate, 
glabrous, more or less glaucous at the nodes, bearing two sheaths, the lower of which 
bears a short leaf. Panicle 2-3 in. long, i-1 in. diam., oblong-lanceolate, moderately 
compact, with semiverticillate, erect, glabrous branchlets and pedicels. Spikelets 11-13 
lin. long, ellipsoidal, 1-2-flowered. Empty glumes 3, glabrous. brown or blackish; the 
lowest #-1 lin. long, 3 lin. broad, oblong or elliptic-oblong, obtuse, 2-nerved ; the 2 inner 
1i lin. long, 4 lin. broad, elliptic, obtuse, deeply boat-shaped, 6-7-nerved. Flowering 
glume 1 lin. long, elliptic, obtuse, deeply concave, 5-nerved, glabrous, smooth, whitish. 
Pale similar to the flowering glume, but smaller and flatter, 2-nerved, whitish. Anthers 
€ lin. long, very dark purplish brown. Stigmas 2, densely plumose, brown or fuscous. 
Summit of Mount Roraima, 8600 ft., WeConnell & Quelch, 675. 
Allied to Panicum loreum, Trin., but the leaves and panicle are shorter than they are 
in that species, the spikelets rather larger, and the leaves quite destitute of a ligule, the 
absence of which is its most remarkable character, since there are few grasses in which 
all trace of a ligule is absolutely wanting.

lo2o) ARUNDO RORAIMENSIS, N. E. Brown, sp. n. Planta 4-3 ped. alta, culmo ad apicem laxe 
folioso glabro. Folia linearia, complieata, apice oblique subacuta, subrigida, glabra

flores articulata. Glumæ 2 inferiores vacuæ, subæquales, lineares, acutæ vel minute
