8. semiberbe has been referred to Andropogon hirtiflorus, Kunth ( Schiza - 
chyrium domingense, Nash), which has not only the backs of the joints and 
pedicels, but also that of the lower glume hairy all over. This state has so far 
not been observed outside tropical South America. In Brazil both 8. semi - 
berbe and 8. domingense seem to grow together and have repeatedly been 
distributed together in the same collecting (e.g., Glaziou, 22540 from Goyaz, 
17441 from Minas Geraes ; Burchell, 6877 and 6885 from the same locality near 
Goyaz, etc.). The variety leptostachyus as defined by Hackel is apparently 
only a much branched growth-form of the variety imberbis, occurring in 
tropical West Africa along with the less branched state of typical S. semiberbe. 
8. semiberbe ranges all over tropical Asia and a great part of tropical America. 
^ 10. S. ursulu s Stapf. Perennial, compactly csespitose, with 
intravaginal innovations. Culms erect or shortly ascending, wiry, 
about 5- to many-noded, slightly compressed below, terete above, 
with the internodes shortly exserted, fastigiately branched from the 
lower nodes upwards ; branches solitary, the lower up to 5-noded, 
all flowering. Leaves more or less hirsute or villous all over, indu- 
mentum greyish or fulvous, at length partly evanescent, lower 
sheaths much compressed, keeled, firm, long-persistent, upper 
terete ; ligules very short, truncate, scarious ; blades narrowly 
linear, acute, usually folded, flexuous, up to 9 in. by 1 lin. (unfolded), 
firm, midrib very slender, primary lateral nerves very close, about 
3-4 on each side ; spathes very narrow, with rudimentary setaceous 
or mucro-like blades. Eacemes on filiform peduncles, slightly thick- 
ened upwards, which are enclosed in or shortly exserted from the 
spathes and 1J-2J in. long, fulvously villous all over, somewhat 
flexuous, 1J-2 in. long ; joints filiform, thickened upwards with a 
subdent ate cupular appendage, densely hairy on the back and sides, 
hairs increasing upwards, 2-2J lin. long ; pedicels similar, but 
slightly shorter. Sessile spikelets narrowly linear-lanceolate, acumi- 
nate, 3J lin. long, including the shortly bearded callus which is § lin. 
long. Glumes subequal ; lower 2-dentate, thinly chartaceous, flat 
on the back, with narrow sharply inflexed margins, with about 6 
inconspicuous intracarinal nerves ; upper narrowly lanceolate, acumi- 
nate, membranous, pubescent, ciliolate, finely 3-nerved. Lower 
floret reduced to an oblong purplish hyaline 2-nerved ciliolate valve 
3 lin. long. Upper floret $ : valve linear-oblong, 2-fid to the middle, 
hyaline, ciliolate, 3-nerved, lobes linear, acute ; awn fine, about
