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

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

 as i 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.

Sttms 4-16 in., tufted, rigid. Zeavet 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-i by -i in., cylindric or ellipsoid, up 

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

 usually 2. Style somewhat shorter tbau nut, often glabrous. Ifut as long as i 

 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 1". 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.
