Common throughout the Old World, in tropical and warm regions. J3. capillaris, 

 Kunth, abounds in the New World; it has the nut definitely transverse wavy, and 

 sometimes has radical (i.e. stemless) spikelets. So, in some Abyssinian specimens, 

 there are added cleistogamous radical almost subterranean 1-nutted spikelets. 



21. B. pubenila, Kunth, Enum. ii. 213, cf. 205. A densely 

 tufted annual. SteDis 2-12 in. long, setaceous, at the top hairy. 

 Leaves J as long as the stem, setaceous; sheaths with long white hairs 

 in the throat. Spikelets in a simple or compound umbel very nearly 

 contracted into a head ; the pedicels of the solitary spikelets often only 

 -i^-YJi i^' long ; bracts long or short, setaceous. Spikelets i in. long, 

 lO-flowered, oblong, dark-brown. Glumes boat-shaped, ovate, hardly 

 acute, pubescent. Style o-branched. Nut J the length of the glume, 

 trigonous, obovoid, truncate, pallid, transversely marked by wavy hues ; 

 style-base persistent on the nut, small, ovoid, depressed, dark red. — C.

'I'he South American plants referred hither by Boeckeler are B. lar.gsdorffiana 

 Kunth, which is a \ery closely allied species. Boeckeler's Senegal Scirpus puberulus 

 is for me Fimhristylite exilis, Roeni. & Sch. The present platit has the umbel 

 so much contracted that it^is never referred to B. capillaris, but (as by Boeck»ler 

 generally) to £. barbata. It might be treated as a variety of B, barbata, with a 

 slightly loosened inflorescence, but that it further differs by the stem being hairy at 

 the top. 



22. B. Taylori, C. B. Clarke in Durand <L' Schinz, Conspect. FL 

 Afr. V. 616. Umbel simple, of 1-5 spikelets; rays up to J in. long. 

 Spikelets ovoid, chestnut-red. Glumes minutely hairy. Style 3-fid ; 

 style-base persistent on the nut as a discoloured button. Kut acutely 

 triquetrous with concave faces, much contracted at the base, pear- 

 shaped ; otherwise as B. capillaris. — Fimbristylis Taylori, K. Schum in

This is separated from B. capillaris. It is more strongly marked than several 

 species recorded here as being admitted by Kunth or other judicious authors. It 

 must be understood that the genus Bulbostylis is very homogeneous, and that 

 we have here a number of plants which will not match, though the points separatire 

 them are of very small botanic significance.
