202 XXVIII. GRAMINEA, [Melinis 
shortly stalked, with a dense crimson tomentum, 13 to 1} line 
long; glume I. obsolete ; gl. II. ovate with shortly bilobed apex, 
T-nerved, veins not anastomosing, back and margin densely hairy, 
awn less than twice its own length; gl. III. similar but slightly 
shorter, 5-nerved, broadly oblong-elliptical, mucronate, sheltering 
a subequal pale with a male flower; fertile gl. ovate, very blunt, 
5-nerved, glabrous, subcoriaceous, enclosing a subequal pale and 
a % flower; seed narrowly ellipsoidal. 
Widely spreading culms up to 2 ft. (perhaps longer), internodes 
increasing upwards from about 2 to 2 in. long (not including the 
flowering one), 2 line or less in diameter, puberulous below the 
tomentose nodes, otherwise glabrous. Ligule about 1 line long ; 
blades 1 to 12 in. long, 2 to 4 lines broad. Panicle 2 in. or less in 
length, by 2 line or less in width, branches and pedicels deep 
crimson ; spikelet surrounded by a basal tuft of hairs borne just 
below the joint, less than the length of the spikelet ; gl. I. repre- 
sented only by a shortly-hairy rudiment ; gl. IT. the length of the 
spikelet, awn a little over 2 lines long; gl. III. a little over 1 line 
long ; fertile gl. barely 1 line; seed 3 line long. 
Is most nearly allied to the last species, but distinguished by its 
membranous densely tomentose glumes.
