median groove and a large pit on each side of it at the upper third 
quarter, keels finely scaberulous, nerves 2-3 on each side of the groove ; 
upper glume thinner, oval-oblong, finely 3-nerved, minutely notched, 
with a fine bristle up to 3 lin. long from the notch. Lower floret 
reduced to a linear-oblong 2-nerved glabrous hyaline valve. Upper 
floret ^ : valve 2-fid to one-third, lobes linear-lanceolate, glabrous, 
awn robust, about 1 J in. long, bent at and twisted below the middle, 
column dark brown, scabrid, bristle pale ; valvule 0. Grain oblong, 
dorsally subcompressed, 1J lin. long ; embryo half as long. Pedi- 
celled spikelets lanceolate, neuter, 3J-4 lin. long, greenish, with or 
without pits, often more or less involute from the sides ; lower glume 
minutely 2-dentate, with a bristle 3-4 lin. long from the notch, upper 
shorter, hyaline, 3-nerved; valves if present linear, often very small.

A very aberrant type of uncertain position. The large pits of the lower 
glume of the fertile spikelets are unique in the genus.

59. Andropogon mobukensis, Chiov. in Ann . di Bot. Roma, vi. 147. 
Perennial. Culms very elongated, branched, slender. Leaf -blades 
short, quite glabrous, linear, contracted at the base into a short 
petiole ; ligules minute. Panicle ? Peduncle longer or shorter 
than the spatheole, hardly scaberulous upwards. Racemes greenish, 
9-12 lin. long, 4-5-jointed, one sessile, the other with a distinct bare 
base ; joints densely white-ciliate, half as long as the fertile spikelets ; 
pedicels three-quarters as long as the latter. Fertile spikelet 
lanceolate, quite glabrous ; callus very obtuse. Lower glume 
depressed on the back, 9-nerved, nerves visible all along, scabrid ; 
upper with a very short terminal bristle, quite glabrous. Lower 
floret reduced to an obtuse ciliate hyaline valve. Upper floret ^ : 
valve 2-fid to one-quarter, awn “ equalling one-third of the lower 
glume.” Pedicelled spikelets lanceolate-linear, acuminate, 
muticous, quite glabrous ; lower glume not dorsally depressed ; 
valve 1 only.

The author places this species next to A. hirtus, L. ( Hyparrhenia hirta). The 
description of the awn suggests some printer’s error ; its length would work out 
at about 1 lin. Can this be one of the Diplandrce series near Hyparrhenia 
andongensis or H. gldbriuscula ?
