Tufted, annual. Leaves i-H in., many-nerved, often recurved. Scapes striate, 

 hardly grooved; sheath tumid, tips membranous. Heads ^-J in. diam. ; in vol. 

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

 villous ; flowei's snbsessile ; 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, m Journ. Bot. xxiii. (1885), 270 ; rootstook 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 npper 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 j rootstock flexuous ; roots copious, long. Leaves 

 8-10 by about ^ in., solid, compressed, cbanelled, 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 seea by me is in 

 a very young state, with the flowers not available for analysis. Compared. Dahellii. 



E. CETLANicuM, Koem. m Linncea, xxvii. 667 ; a foot high, stem very short, 

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

 large cyliudric-globose woolly white i 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, fem. fl. sessile, sepals 

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

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

 Ceylon, Herb. Berlin. — Evidently near S. atratum, but leaves mucronate. 



E. EUETPEPLON, Keen. 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 l|-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. —

E. HETEEOLEPis, Steud. %». PI. Cyp. 271 ; Koem. I. e. 572 ; tufted, stem very

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

 fid Koem. more probably E. Sieloldianum. 



B. NEESIANTIM, KcBrn. I.e. 628. — Ceyloa {Herb. Berol.). — Is likened to irara- 

 catum and aehiton 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, Koem.
