$S^ TP.IANBP.IA MONOOYN-lAi Schf.lP, 



brown.— ScrtZ^'s roundish oval, concave, chaffy, brown, sinootli; the 

 jib or nerve ending ui a subulule j)oint beyond llie rounded apex= 

 — Stamens tlnee on the exterior side of the germ, one-bearded bris- 

 tle between each filament, and three on the back, making in all five. 

 — Germ ovate. — Stijle with sweUetl, permanent, cordate l>ase. — 

 Stigma tlnee-cleft. — Seed oblong, three-sided, snrrouuded by the 

 ijve-beardcd bristles. 



ObS' It approaches Sc. grossus. Fald. Enum.'n. 270; the best 

 marks to distinguish them by, are ihe bristles which embrace the germ, 

 aiid continue with the seed; here they are five in nuniber and vil- 

 lous, there six, and barbed, or armed on the margin, with sharp brie- 

 lies pointing backwaid. My Sc. maximus is a mucli larger species, 

 and the germ destitute of bristles.

-Cuhns erect, from six to ten feet high, triangular. Umbel super- 

 decompound. Sect/ three- sided, beset with six, backwardly hispid 

 bristles. 



Exclude Sc. grossus. Uetz. Obs. v. 15. which I presume is my Sc. 

 waxim<i!s ; the germ and seed being there destitute of the bristly in- 

 volucre. To which of these Sc. grossus, Linn. Suppl. ought to be 

 referred, I cannot say. 



This, next to Sc. maximus, is by far the largest species I have ever 

 mef with. It grows in standing sweti water. 



Culm erect, mostly naked, from six to ten feet high, three-sided; 

 angles sliarp, skies concave — J.eares radical, and round the base of 

 the culms sheathing, much keeled, almost as long as the culms ; 

 edges slightly scabrous. — Umbel super-decompound, fiv€ or eight 

 inches oach way. — Inxohicre. three-leaved, the largest about two feet, 

 the shortest six inches, they taper to a long, acute point ; margins 

 pretty ■sn\oo\S\.~InvoIuceh chaffy.— Spj7c£S oblong, daik-brown, 

 many-flowered. — Stamens three, with two bristles between each pair./ 

 —Style three-cleft. — Seed three-sided, embraced by the six enlarged 

 bristles, which are armed on ;he edges with stiff, bent back, short 

 hairc.
