of about 3 erect arching spike-like racemes ; common axis somewhat 
stout, densely and roughly ciliolate at the angles. Racemes secund, 
1-seriate, not quite 1 in. long ; rhachis flat, densely setulose-ciliate. 
Spikelets subsessile, solitary, contiguous, elliptic, acute or acuminate, 
2 lin. by ~ lin., greenish hairy. Lower glume broadly ovate, with 
rounded and more or less asymmetric tips, one-third to almost half the 
length of the spikelet, glabrous, 9-nerved ; upper glume broad- 
elliptic, acute or broadly acuminate, 5-nerved. Lower floret $ : 
valve like the upper glume if not broader ; valvule as long as the 
valve or almost so, shortly acute. Upper floret elliptic, subacuminate ; 
valve and valvule crustaceous, rugulose, yellowish-shining.

51. B. jubata A Stapf. Perennial, up to 3 ft. high. Culms erect, 
simple, the exposed parts hirsute with yellowish hairs. Leaf- 
sheaths striate ; ligules a densely ciliolate rim ; blades linear, taper- 
ing gradually, very acute, up to 5 lin. wide, flat, spreadingly ciliate. 
Inflorescence long-exserted, about I in. long, secund, of erect or 
falcate distant secund spiciform racemes ; common axis semiterete, 
slightly channelled on the face. Racemes dense, 2-seriate, lower 
not quite an inch long, the following gradually shorter ; rhachis 
slightly flexuous, somewhat flattened with a prominent midrib on 
the finely pubescent face, margins densely ciliate with yellowish 
hairs almost as long as the spikelet ; pedicels very short, setulose 
with subdiscoid tips. Spikelets contiguous, oblong, obtuse, about 
2 lin. long, hairy. Glumes subequal, membranous ; lower almost 
as long as the spikelet, broadly elliptic-oblong, very obtuse or sub- 
marginate, clasping below, glabrous, ll-12~nerved, nerves ending 
free, upper ovate-oblong, obtuse, as long as the spikelet, much 
narrower than the lower glume, appressedly hairy, 7 -nerved with 
cross-veins. Lower floret as long as the spikelet, $ : valve 5-nerved, 
upwards with cross-veins, hirsute along the sides and upwards ; 
valvule elliptic-oblong, keels marginate. Upper floret subelliptic 
in outline, apiculate ; valve and valvule crustaceous, very delicately 
rugulose, the former with some cross-nerves near the apex. Stigmas 
large, purple. — Panicum jubatum, Fig. & De Not. in Mem. Acc.

According to Eigari’s fig. 1, which is stated to be to the scale of x 3 natural 
size, the spikelets would be 2 lin. long, but according to figs. 2 and 3 (magnifi- 
cation 5) their length appears to be 3 lin. Evidently allied to B. fulva, but 
apparently differing in the larger size of the spikelets and the broader and 
more numerously nerved lower glume.
