This plant is altogether like weak examples of B. capillaris, var. trifida, except 
that the nut is very conspicuously transverse undulate. It is difficult to say how it 
differs from the American B, capillaris, 
26. B. filiformis, 0. 2B. Clarke. A very slender annual. Stems 
tufted, 1-3} in. long, setaceous, with spreading needle-like white hairs 
from top to bottom. Leaves 4 the length of the stem, filiform, hairy. 
Spikelets 1-2 to each stem, 4-4 in. apart, j4,— 7/5 in. in diam., ovoid- 
globose, chestnut-brown; bracts setaceous, hardly overtopping the 
inflorescence. Glumes boat-shaped, ovoid, with a short point, pubescent. 
Style 3-branched. Nut 4-2 the length of the glume, trigonous, 
obovoid, pale brown, transversely wavy-marked ; style-base persistent 
on the nut, small, ovoid, dark-brown.

If hairs are to be depended on for specific distinction, the needle-like hairs on the 
stem of this plant, never seen on B. capillaris, distinguish it; but beyond these hairs 
there is little to distinguish it from small B. capillaris. 
27. B. abortiva, C. B. Clarke in Durand d Schinz, Conspect. Fl. 
‘fr, v. 610. Rhizome 0. Stems 6—24 in. long, very slender, densely 
tufted at the base, glabrous at the top. Leaves half the length of the 
stem, capillary ; sheaths with a few long white hairs in the throat. 
mbel up 4—6 in. in diam., compound, with very numerous pedicelled 
spikelets ; bracts setaceous, much shorter than the umbel, usually 
‘conspicuous. Spikelets, glumes, style and nut, as of B. capillaris.—
