25. F. rigridula, Nees in Wight Contrib. 99 ; rhizome horizontal 

 woody short, leaves longish, umbel once or twice compound, spikelets 

 very obtuse solitary and paired, style 2-fid, nut obovoid smooth dirty 

 straw-colrd. F. Hanceana, Boeck. in Linnsea, xxxviii. 394. Fimbristylis,

Stems 4-16 in., thickened at- base, closely 1-seriate on rhizome. Leaves as long 

 as ^ culm, glabrous, or (with their sheaths) pubescent ; tip subobtuse. Umbel 1-5 

 in. diam., somewhat lax; bracts short, Spikelets i- ^ in., ellipsoid or subglobose. 

 Nut nearly as of F. ferruginea, but paler, less glistening ; outermost cells in 20-30 

 series on each face, i.e. nut minutely reticulate, faintly 20-30 striate longitudinally. 

 Well-marked by the rhizome and paired subglobose spikelets. The F. rigidula, 

 Herb. Berol. reduced to F. diphylla by Kunth and Boeckeler, is not the plant of 

 Nees. 



26. F. spathacea, Both. Nov. PI. Sp. 24; leaves short rigid, umbel 

 compound with solitary spikelets often contracted sometimes subcapitate, 

 glumes obtuse often notched, style 2-fid, nut obovoid smooth or somewhat 

 tubercled dusky. F. Wightiana, Nees in Wight Contrib. 99 ; Thw. Enum.

Stems 4-16 in., tufted, rigid. Leaves as long as stem (often much shorter), 

 narrow, glabrous, margins incurved. Umbel 2 in. diam. in well-developed examples, 

 usually somewhat dense with solitary but closely approximated spikelets ; in less 

 developed examples the spikelets are nearly or quite clustered, sometimes virtually 

 in a single head ; bracts short, broad. Spikelets i-| by -^ in., cylindric or ellipsoid, up 

 to 60 in an umbel. Glumes ovate, concave, incurved, margins scarious. Stamens 

 usually 2. Style somewhat shorter than nut, often glabrous.' Nut as long as f 

 glume, biconvex, shortly stalked. This plant offers a transition to the next series 

 (F. argentea, sericea, &c.) by the often clustered spikelets; Boeckeler appears only 

 to know this contracted form (which is not Nees' type), and to have placed it (on 

 account of such occasionally contracted heads) in the 3-stigma group of F. cymosa, 

 iunciformis, &c. In F. spathacea, the style is never 3 -fid. 



Series B. Spikelets, or some of them, clustered. (See also F. spathacea, 

 F. rigidula, and occasionally F. diphylla in series A, B.) 



* Stems with only one head.
