Stem 3 angled ; pani- 

 cles decompound, axilla- 

 ry and terminal, pendu- 

 lous ; spikelets clustered ; 

 seed obovate, rugose, 

 guarded by bristles. 



Stem 2 — 3 feet liigh, S angled, glabrous. Leaves linear, short. 

 ■Panicles almost naked, the bracteal leaves being very short. Spikelet» 

 ovate-lanceolate, very n v-merous, nearly sessile, clustered. Glumes 

 ovate, nmcronate, ferruginous. Stamen s 3. Style very long, S cleft. 

 *S<'pd obovate, compressed, transversely rugose, ferruginous, crowned 

 with a conic, white tubercle, and surrounded with bristles longer thaa 

 itself. 



This species is somewhat remarkable. The structure of the flowet 

 Is strictly that of a Scirpus ; the spikes contain many glumes, each 

 covering a seed with ita usual appendages ; yet the seed, the tuber- 

 cle, the surrounding bristles all resemble those of a Sc cenus ; and 

 the plant itself in habit and appearance would occupy an intermediate 



*«pace between the Sch. expansus and caducus*
