Tufted, annual. Leaves $-1$ in., many-nerved, often recurved. Scapes striate, 

 hardly grooved; sheath tumid, tips membranous. Heads - in. diam. ; invol. 

 bracts scarious, stellately spreading, pale, shining, often lacerate ; receptacle convex, 

 villous ; flowers subsessile ; male sepals 3, free (or 2 connate) ; petals minute or 

 obsolete ; fern, sepals rarely 3, the third capillary. Seeds much narrower than in 

 most other species, linear-oblong, papillose all over, pale yellow. 



IMPERFECTLY KNOWN SPECIES. 



E. fluviatile, Trim, in Journ. Sot. xxiii. (1885), 270 ; rootstock very 

 slender, leaves scattered very slender, scape solitary, heads small depressed 

 globose, invol. bracts roundish-oval brown, floral linear-oblong with coarse 

 white hairs on the upper part, fl. dioecious ? fern, sepals linear-spathulate, 

 petals narrower membranous tipped with scanty white hairs. 



CEYLON ; Western province, in rapid stream, Trimen. 



Submerged except the head ; rootstock flexuous ; roots copious, long. Leaves 

 8-10 by about J T in., solid, compressed, chanelled, flaccid; sheath dilated, cottony 

 within. Scape rather shorter than the leaves ; sheath not dilated, tip acute. Head 

 in. diam. (receptacle?). Descr. from Trimen. The only specimen seen by me is in 

 a very young state, with the flowers not available for analysis. Compare E. Dalzellii. 



E. CEYLANICUM, Kosrn. in Linncea, xxvii. 667 ; a foot high, stem very short, 

 leaves 2-3 in. tufted linear suddenly mucronate, scapes solitary 1 in., heads rather 

 large cylindric-globose woolly white 4 in. long, invol. bracts obovate at length 

 hidden under the head, floral cuneate -obovate submembranous pale, receptacle hairy, 

 male sepals obtuse membranous, anticous petal much largest, fern. fl. sessile, sepals 

 free acute like those of the males, petals 3 spathulate obtuse spongy anticous much 

 the largest far longer than the sepals. Hairs of bracts and perianths obtuse. 

 Ceylon, Herb. Berlin. Evidently near IE. atratum, but leaves mucronate. 



E. EURYPEPLON, Kcern. I.e. 685; 2-3 in. high, leaves 3 in. tufted broadly 

 linear narrowed upwards tip obtuse membranous, scapes crowded 4-winged 1^-3 in., 

 heads subglobose lf-2i in. broad powdery pubescent and nigro-niveous, invol. 

 bracts rigid powdery- pubescent olive-black much shorter than the heads, floral 

 rhombic-cuneate olive-black rigid closely imbricate hiding the fl., receptacle hairy. 

 Ind. Or. 



E. HETEROLEPIS, Steud. Syn. PL Cyp. 271 ; Kaern. I. c. 572 ; tufted, stem very 

 short, leaves lanceolate from a broad base subobtuse, hardly 1 in. long. Bombay, 

 Roux. 



E. MINIMUM, Lam.Encycl.iii.275 ; Kunth Enum. Hi. ; Steud. Syn. PI. Cyp. 268; 

 A. Rich. Tent. Fl. Abyss, ii. 347?; Koern. 1. c. 635. Ind. Or., Sonnerat. (Herb. 

 Lamarck). Male sepals 2, free, linear-oblong. Perhaps a form of E. truncatum, 

 fid Kcern. more probably E. Sieboldianum. 



E. NEESIANUM, Koern. I.e. 628. Ceylon (Serb. Serol.). Is likened to trun- 

 catum and achiton by its dimerous sepals, but the receptacle is shortly villous. 

 Very like E. viride in the head, differs in the form and number of the perianth seg- 

 ments and the obtuse floral bracts, Koern. 



ORDER CLXXII. CYPERACEJE By C. B. Clarke, F.E.S. 



Grass- or rush-like herbs. Stems solid. Leaves 3-ranked, rarely ; 

 sheaths closed. Flowers 1-2-sexual, small or minute, solitary in the axils of 

 the scales (glumes; of the spikes or spikelets that are solitary or variously 

 disposed on the stem. Perianth 0, or of hypogynous bristles or scales. 

 Stamens 1-3, rarely more ; anthers linear, basifixed on the flattened fila-
