distant by less than their own length ; pedicels slightly widened 
upwards with truncate tips, the lateral J-1J lin. long. Spikelets 
lanceolate to lanceolate-oblong, acutely acuminate, 1J lin. long, pale 
greenish. Glumes very unequal; lower broadly ovate, clasping, 
acute to subobtuse, a quarter to one-third the length of the spikelet, 
subhyaline, imperfectly 3-6-nerved, the midnerve percurrent, the 
side-nerves very short to (the inner) half as long as the glume, 
obscurely anastomosing ; upper corresponding in size and shape 
to the spikelet, membranous, prominently 7-9-nerved. Lower 
floret barren, with or without a more or less reduced valvule ; valve 
like the upper glume, mostly 9-nerved. Upper floret £>, oblong, 
subacute, 1 lin. by almost J lin., smooth, glossy, yellowish; valve 
and valvule thinly crustaceous. Anthers J lin. long. Grain over

The P. proliferum of authors covers a number of allied yet clearly distinct 
species. The name is Lamarck’s, but since Hitchcock (in Contrib. U.S. Nat. 
Herb. xii. 147) has shown that his plant so named is identical with P. miliare, j 
Lam., P. proliferum becomes a synonym unconnected with any of the forms so far 
referred to it. Of these, one, namely Hooker’s P. proliferum (FI. Brit. Ind. vii., 
50), is identical with Roxburgh’s P. paludosum (Roxb. FL, Ind. ed. Carey, i. 310), 
another, a native of America, is P. dichotomiflorum, Michx (FI. Bor. Am. i. 48). 
Both appear to me sufficiently distinct from the African plant described above ; 
P. paludosum mainly by its conspicuously larger and more finely acuminate 
spikelets ; P. dichotomiflorum by its pronounced branching habit and the smaller 
number of nerves of the upperglume (mostly 7) and lower valve (5-7, mostly 5). 
73. P. pectinatum, Rendle in Trans. Linn. Soc. ser. 2, Bol. iv. 54. 
Perennial, compactly csespitose, up to 2 ft. kigh, with intravaginal 
innovations. Culms very slender, erect, terete, 1-2-noded, upper- 
most internode at length more or less exserted, glabrous and smooth.
