Hypanhenia.\ clvii. gramineje (Stapf). 
381 
Leaf-sheaths loose, glabrous ; ligules 6-8 lin. long, truncate, subden- 
ticulate, glabrous, membranous ; blades linear, flat or often narrow 
with involute margins, very acute, scabrid. Inflorescence consisting 
of 2-4 very distant raceme-pairs, borne on very long glabrous some- 
what stout rays. Spatheoles very long, convolute, acute, glabrous ; 
peduncle exceeding the spatheoles, scabrid. Racemes yellowish- 
villous, one sessile, the other with a long base, each consisting of 
1 fertile awned spikelet and 5 spikelets of which the lowest 3 are 
subsessile whilst the 2 others are pedicelled ; pedicels densely ciliate. 
Fertile spikelet surrounded by yellowish silky hairs at the base 
(callus ?). Lower glume truncate, 2-dentate, nerved, fulvously 
silky ; awn very long, fulvously silky. Pedicelled spikelets 
glabrous ; lower glume aristulate, upper acute. Homogamous 
spikelets muticous. — Hack, in DC. Monogr. Phan. vi. 633 ; Durand

This species ought to be easily recognized by its unusually long ligule. This 
it has in common with Hyparrhenia petiolata ; but the much reduced inflores- 
cence, the scabrid but not bearded peduncles, and the very unequal raceme- 
bases, one of which is described as “ long,” and finally its perennial duration, 
exclude it from that species. The statement that there are 5 6 spikelets 
is probably erroneous. If there are 2 terminal pedicelled spikelets they would, 
together with the solitary fertile spikelet, form the usual terminal trio, below 
which one might expect 1 or 2 pairs of homogamous 6 spikelets, bringing up the 
number of 6 spikelets to 4 or 6. If there be 6, the affinity of the species would 
evidently lie with the Filipendnlce series.

Afr. Exped. 1907-8, ii. 44 (1910). Perennial. Culms about 3 ft. 
high, erect, stout, coated at the base with long imbricate sheaths, 
4-noded below the panicle. Leaf-sheaths (upper ?) shorter than the 
internodes, hirsute upwards, setose at the mouth ; blades very long, 
rigid, narrowly linear, 2J-3 lin. wide, “ involute, hairy on the upper 
side,” scabrid along the margins, “ midrib stout, impressed on the 
lower side.” Panicle over 2 ft. long, narrow, very scanty and loose, 
almost interrupted, with more or less erect branches. Spatheoles 
narrow, cymbiform, rufescent ; peduncle two-thirds as long as the 
spatheoles, densely bearded upwards with long yellowish stiff hairs. 
Racemes 4-awned per pair, at length epinastically reflexed, one 
sessile, the other with a base 1 lin. long ; bases bearded like the 
peduncle, their tips produced into a broad 2-fid or -dentate 
bract-like appendage, 1 lin. long ; joints and pedicels slender, 
1J lin. long, white-ciliate. Homogamous pair of spikelets 1 with 
the lower raceme. Fertile spikelets narrow, ovate-lanceolate, 
slightly over 3 lin. long ; callus short, acute. Glumes : lower rigid, 
2-dentate, flat on the back, the innermost 3 nerves prominent, the 
outer obscure ; upper ovate-oval, obtuse, shortly cuspidate, hairy 
towards the margin. Lower floret reduced to a very delicate valve 
with indexed margins. Upper floret ^ : valve 2-fid, ciliate ; awn
