Pearson’s specimen has the inflorescence characteristic of B. Isachne, but 
its spikelets approach rather those of B. poceoides (see below). 
42. B. poaeoides, Staff. Annual, up to 2 ft. high, loosely tufted. 
Culms geniculate-ascending, slender, much branched below, terete, 
glabrous or the lowest internodes hairy, about 4-noded, the upper- 
most internode far exceeding the others. Leaf -sheaths terete, the 
lower loose and slipping off the culm, the upper tight, striate, softly 
and loosely hairy, villosulous at the nodes ; ligules reduced to a 
fringe of short hairs ; blades linear from a shortly narrowed base, 
long-tapering to a slender point, 3-4 in. by 3-7 lin., flat, flaccid, pale 
green, finely and loosely pubescent, margins scaberulous, nerves 
numerous, close and very fine, midrib very slender, whitish. Panicle 
ovate in outline, sometimes subsecund (the upper part), 3-6 in. 
long, up to over 2 in. wide, loose ; branches obliquely erect or 
spreading, finely filiform, often flexuous, scabrid and like the primary 
axis loosely and finely pubescent, the lower often 2-nate, up to over 
3 in. long, bare for in., then bearing up to 5 peduncled short 
racemes, or like the upper primary branches reduced to a single 
secund raceme. Racemes secund, simple, dense, up to over 4 lin. 
long or the lower compound and often interrupted at the base with 
short pauci-spiculate secondary racemes ; rhachis finely filiform, 
J lin. wide, more or less straight, subtriquetrous below, more or less 
semiterete upwards, scaberulous and puberulous ; pedicels solitary, 
very short, tightly appressed to the rhachis, of the same vestiture 
as the rhachis, with obscurely discoid tips. Spikelets of the longer 
racemes 2-seriate, distant by about J lin., imbricate or laterally 
contiguous, of the short racemes more or less clustered, all oblong, 
subacute to almost obtuse, flat on the back, 1 \ lin. long, pale greyish- 
green, often tinged with purple, softly pubescent. Glumes very 
unequal ; the lower reduced to a minute hyaline nerveless broad- 
ovate scale, the upper corresponding in outline and size to the 
spikelet, thinly membranous, finely 5-nerved, tips very minutely 
denticulate. Lower floret neuter or g (?) : valve similar to the 
upper glume, but less pubescent and much depressed between the 
inner side-nerves ; valvule oblong, obtuse, somewhat shorter than 
the valve, obtuse ; anthers rudimentary. Upper floret oblong 
to elliptic-oblong, whitish or ultimately light brown, very glossy and 
smooth ; valve and valvule thinly crustaceous. Anthers J lin. long.
