Andropogon.] clvii. gbamine^b (Stapf). 
spikelets, the width of the wings, and the degree of hairiness differ within the 
racemes of the same individual ; the sexual conditions are similarly unstable 
in this and the immediately allied species. The specimen at Kew from Loetha, 
fichimper, 476, differs in no way from what Hackel calls typical A. polyatherus. 
A. Richard evidently came to the same conclusion in so far as the subvarieties 
1, 4 and 5 — the only ones known to him — are concerned, and abstained from 
giving them a special status within the species. 
8. A. kilimandscharicus, Pilger in Engl. Jahrb. xliii. 384. Per- 
ennial, compactly caespitose, innovations intravaginal, very numerous, 
usually very short. Culms simple, slender, erect, 3-9 in. high, com- 
pressed below, glabrous, smooth or hairy towards the tips, 1-2- 
noded. Leaf-sheaths smooth, striate, glabrous except for a beard 
of hairs at the mouth, those of the innovations compressed and more 
or less keeled, 1 to over 2 in. long, the cauline terete, rather tight, up 
to 2 J in. long ; ligules very short, rounded or truncate, long-ciliate ; 
blades very narrow, linear to filiform, subacute, somewhat rigid, 
1J-2J in. long, |-1 lin. wide, flat or convolute, glabrous, more or less 
scabrid, particularly upwards and along the margins, midrib very 
slender, primary nerves about 2 on each side, very fine ; subtending 
leaves spathaceous,subherbaceous, narrow, soon convolute and tight, 
with short subfiliform blades. Peduncle 2-4 in. long, hairy towards 
the tips. Racemes 2-nate, one sessile, the other with a short base, 
1-1 b in. long, erect, densely villous ; joints and pedicels linear, hardly 
widened upwards, 1J lin. long, densely ciliate on both sides, cilia 
1 lin. long, tips truncate. Sessile spikelets all heterogamous (except 
the lowest of the sessile raceme which is $ and awnless), linear- 
lanceolate, 3 lin. long ; callus short, obtuse, bearded. Glumes sub- 
equal, low r er chartaceous, finely acuminate, minutely 2-denticulate, 
white-hairy on the back, keels minutely scaberulous, intracarinal 
nerves 2, with 1-2 additional short ones above the middle, tips 
nerveless and hyaline between the keels ; upper glume subchar - 
taceous, narrowly boat-shaped, 3-nerved, with a small bristle from 
a terminal notch, hyaline margins broad up - wards, densely ciliolate. 
Lower floret reduced to an oblong subobtuse 2-nerved ciliolate 
hyaline valve. Upper floret ^ : valve over 2 lin. long, shortly 
oblong, shortly 2-fid, with acute lobes, ciliolate, 3-nerved below ; 
awn very fine, 3-6 lin. long, kneed at and twisted below the middle ; 
valvule 0. Pedicelled spikelet $ , oblong-lanceolate, acute, 2-2 J 
lin. long ; lowrer glume subchartaceous, more or less hairy, with a 
distinct raised middle nerve and three very close and fine nerves 
in the keels, upper acutely acuminate, 3-nerved ; valve of lower 
floret oblong, acuminate, 2 lin. long, hyaline, 2-nerved, ciliate, 
of upper linear-oblong, lin. long, 1-nerved, minutely emarginate ; 
anthers 1J lin. long.

A raceme infested with Sphacelotheca had diseased ovaries in some of the
