CXLI. CYPERACES. 425 
26. ACROLEPIS, Schrad. 
Spikelets 2-3-flowered. Glumes distichous, the lower 
empty. Perianth 0. Stamens 3. Style deeply 3-fid, equal 
at base, deciduous. Achene crustaceous, 3-angled, umbonate, 
sitting in a cup-like, triangular disk, with a crenate margin.— 
Kunth, 1. c. p. 330. 
Culms much branched, leafy. Spikelets terminal and lateral, peduncled. 
—“The genus differs from Hemichlena by the smaller, few-flowered spike- 
let, furnished at base with an accessory bract, the joints of the rachis closer 
and a thin sterile glume terminating the spikelet.” —Wees.

SCHGENUS, R. Br.—Thunberg has several species under this genus, 
which require re-examination as to their general character. I therefore 
omit the genus.— Kunth, l.c. p. 334, 
TrrBeE 5. Squerinem. (Gen. 27-28.) 
27. SCLERIA, Linn. 
Monecious.—Male: Spikelets mixed with a few female and 
androgynous spikelets, many flowers. Glumes imbricate on 
all sides, the outer subdistichous, empty. Stamens 3-2—1.— 
Female: Spikelets 1-flowered. Glumes few. Styles 3-fid. 
Androgynous spikelets several-flowered, the lower flower 
female, the rest male. Achene stony or crustaceous, on a 
more or less 3-lobed (often ciliate, fimbriate or multifid) disk. 
— Kunth, l.c. p. 339. 
Culms 3-angled, leafy. Leaves 3-5-nerved, rigid, grass-like; vagina 
often prolonged, at both sides, above the starting-poimt of leaf-blade. Spike- 
lets panicled, racemose or spiked.—Several Cape species. 
298. CHRYSITHRIX, Linn. 
Spikelet many-flowered, androgynous, outer flowers many, 
male, monandrous, each from a single glume, central flower 
female, nude. Glumes imbricate on all sides, the inner linear, 
acute, 1-nerved, hyaline-membranous, deciduous, outer larger, 
coriaceous, empty ; receptacle conical. Perianth 0. Anthers 
linear, with a very long, hispidulous crest. Style deeply 3-fid; 
ovary pear-shaped. Fruit ?>—Kunth, 1. c. p. 365. 
Culms strongly compressed, broad, simple, leafy at base. Leaves equi- 
tant, broadly linear, straight, resembling the culm, rigid. Spikelet solitary, 
ovate-oblong, from the axil of a short, terminal, sheathing leaf.—2 species. 
TriseE 6. Caricrinex. (Gen. 29-82.) 
29. CAREX, Linn. 
Spikelets androgynous or monoecious, very rarely dioecious. 
Glumes imbricate on all sides, 1-flowered. Flowers uni-
