422 CXLI. CYPERACES. 
cuneate or lanceolate, membranous scale; valves hyaline, 
covering the flower. Perianth 0. Stamens 2-3. Ovary flat- 
tened ; style 2-fid, equal at base. Achene obovate-clavate, bi- 
convex, shortly stipitate, punctulate, enclosed in the valves of 
the larger palea.—Kunth, l.c. p. 269. 
P. Capensis, our only species, was discovered by Drége on the Katberg 
and in Caffraria. Its culms are slender, tufted, leafy at base, and bear a 
head of 1-3 spikelets, subtended by 2 long involucral bracts. The whole 
plant is very pale.

14. TRIANOPTILES, Fenzl. 
Spikelets 2-flowered, both bisexual. Glumes distichous, 
keeled, boat-shaped, 3 lower empty. Perianth of 3, narrow- 
linear, 3-fid scales, villous-ciliate below ; the lobules bristle- 
shaped, the medial longer. Stamens 3. Style very long, 2-fid 
at the apex, swollen and hairy at the base. Achene obovate, 
flat towards, the axis, convex and obtusely angled in front, 
minutely dotted, beaked, girt by the persistent enlarged peri- 
anth scales; the beak continuous, hairy at tip.—Hndl. Gen. 
113 ; Kunth, l.c. p. 287 (Ecklonia). 
T. Capensis (Ecklonia Capensis, Steud.), found on Table Mountain, has 
simple, leafy culms, and axillary or terminal, subgeminate, many-spikeleted 
peduncles. Spikelets tufted, lanceolate, subcompressed, brownish-straw- 
coloured. 
15. RHYNCHOSPORA, Vahl. 
Spikelets 1-9-flowered, either all the flowers bisexual or the 
lower bisexual or female, the rest male. Glumes imbricate 
on all sides (or imperfectly distichous), 1-nerved, often mucro- 
nate-awned, the lower smaller, empty. Perianth of 6 or more 
or fewer bristles, sometimes minute or wanting. Stamens 3 
(2-1). Style more or less deeply 2-fid, thickened at base. 
Achenes biconvex, beaked with the persistent, conical or subu- 
late, hardened style-base.—Kuwnth, l.c. p. 287. 
Culms leafy. Spikelets capitate, corymbose or panicled, brown or straw- 
colour.—Few Cape species. 
16. CLADIUM, R. Br. 
Spikelets 2-1-flowered, the flowers bisexual, the lower rarely 
male. Glumes imbricate on all sides, lower empty. Perianth 
0. Style 3-fid (rarely 2-fid), conical-bulbous at base, conti- 
nuous. Achene bony, completely covered over by the much 
enlarged, cap-like, adherent base of style-—Awnth, 1. c. p. 303. 
C. Mariscus, an almost cosmopolitan species, is found in Uitenhage. 
Culms tall, leafy, ending in a long thyrsus of densely, much-branched pa-
