13. MANISURIS, Linn. f. ; Benth. et Hook, f., Gen. PI. iii. 1130. 
Spikelets 2-nate, one sessile, the other pedicelled, with the pedicels 
completely adnate to the joints of the rhachis, on the articulate and 
fragile rhachis of fascicled spike-like racemes, conspicuously hetero- 
morphous, alike in sex or the pedicelled neuter ; the sessile deciduous 
with its joint and the pedicelled spikelet belonging to it. Sessile 
spikelet : Florets 2, lower barren, upper $ . Glumes equal, lower 
cartilaginous, subglobose, upper chartaceous, immersed in the cavity 
of the joint. Valves hyaline, muticous. Valvules hyaline, absent 
from the lower floret. Lodicules broadly cuneate. Anthers exserted 
from the apex of the spikelet. Stigmas exserted terminally. False 
fruit nut-like, formed by the hardened lower glume of the sessile 
spikelet and the closely applied joint. Grain suborbicular, very 
convex on the back, almost flat on the face ; embryo large. Pedi- 
celled spikelet : Florets 2, lower barren, upper $ , or more or less 
reduced or suppressed. Glumes equal, herbaceous, ovate. Valves, 
if present, hyaline, the lower without a valvule. — Annual, much- 
branched ; leaves soft ; racemes very conspicuous on account of 
the grain-like fertile spikelets. 
Species 1, throughout the tropics. 
1. M. granularis, Sw. Prodr. Veg. Ind. Occ. 25 (1788). Culms 
erect, up to over 3 ft. high, more or less terete below, compressed 
above the branching level, glabrous or hirsute with tubercle-based 
hairs ; branches 2 or more from a node, unequal, simple or the 
longer divided again. Leaf-sheaths loose to inflated, usually more 
or less compressed, striate, hirsute with tubercle-based hairs, usually 
more or less bearded at the nodes ; ligules very short, mem- 
branous, ciliate ; blades lanceolate or linear-lanceolate, from a 
cordate and amplexicaul base, acute, 2-4 in. long and 4-6 lin. wide, 
more or less hirsute from fine tubercle-based hairs, margins ciliate, 
midrib white and flat above, lateral nerves 5-7 on each side, slightly 
prominent. False spikes J-l in. long, about 1 lin. wide, borne on 
short or long peduncles, partly enclosed in to completely exserted 
from the supporting spathe-like sheath, glabrous, pale green ; joints 
linear, J-f lin. long, the portion corresponding to the pedicel with 
2 fine grooves, that corresponding to the rhachis with 1 broad flat 
groove, both with distinct scars, that of the joint hollowed out. 
Sessile spikelet, including the short obconical callus, from almost 
1 lin. to 1J lin. long, glabrous. Glumes subequal ; lower pitted
