lndropogon] XXVIII, GRAMINES, 145 
Racemes 1 to 11 in. long, terminal and lateral on long thread- 
like branches from the uppermost nodes, protruding from their 
stalked rufous narrowly lanceolate acuminate spathes; rhachis 
brittle, joints (1 line long) with irregularly dentate cup-like 
apex ; sessile spikelet 33 lines long; callus short with a small 
tuft of hairs; gl. I. 34 lines, greenish-red; gl. II. 43 lines 
including the awn (2 lines), blunt, widest at or a little above the 
middle ; gl. a lanceolate, 2-nerved with edges incurved at 
the nerves, 2} lines; fertile glume partite to about the middle, 
2 lines fon “the strong awn springing from between the two 
acute points, brown and twisted below, kneed below or about 
the middle and passing into the pale slender flexuose subula ; 
pale short, truncate, scarcely 12 line; lodicules large fleshy, 
obliquely cuneate, 4 line long. Pedicel 14 lines long, apex 
dentate as in the rhachis-joint, its stiffish hairs reaching } way 
up the outer glume which including the awn is 4 lines long, 
minutely hispidulous on the back and inconspicuously 9-nerved, 
the median awn exceeds the two lateral; gl. II. 3 lines long, 
5-nerved, reddish ; gl. III. 23 to 23 lines, 2- to 3-nerved; gl. IV. 
2 to 24 lines, 1- to 3-nerved, pale as in sessile spikelet ; anthers 
reddish, linear, 14 lines long; lodicules as in sessile spikelet. 
An interesting addition to the subgenus which hitherto has 
contained only the widespread tropical A. fastigiatus Sw. From 
this A. textilis is distinguished by its stiffer habit with more rigid 
leaves, its smaller more compact spikes, the less difference in size 
between sessile and pedicelled spikelet, and the smaller more rigid 
outer glume of the latter. Other differences are found in the 
approach to equality of the outer and inner barren glumes of 
the stalked spikelets, and the more membranous shorter-awned 
and more oval inner barren glume of the sessile. 
Punco ANDONGO.—Widely cexspitose, 2 to 3 ft.; leaves erect, 
elongated, almost subulate and rushlike, subrigid, used by the 
inhabitants to make their so-called Balayas. Common in rather damp 
meadows between N-billa and Bumba ; Mar. 1857. No. 7440.

8. A. festuceformis Rendle sp. nov. 
Cespitose, culms purple, subcompressed, simple below the 
flowering shoots, springing from a tuft of linear-plicate, rigid, 
minutely pungent radical leaves; sheaths flattened, carinate, 
glabrous, ligule short, rounded, blades glabrous except for a few 
hairs on the inner face at the base ; inflorescence strict, the rather 
short lateral branches bearing several short spikes which ultimately 
project slightly above their lanceolate reddish spathes; peduncle 
shorter than the spike, puberulous, apex shortly villous; spike
