Rynchospora. | CLVI. CYPERACE& (CLARKE). 483 
Spikes clustered, many-flowered. Involucre of one leaf, as long as the 
corymb. Glumes ovate, acuminate, adpressedly puberulous. . Hypo- 
gynous bristles 3-6, as long as the nut. Nut (immature) acutely 
triquetrous, smooth, whitish. 
Upper Guinea. Senegambia, Leprieur (ex Steudel). 
If the nut is really triquetrous, the plant is not a Ryachospora. 
17. CARPHA, R. Br.; Benth. et Hook.f. Gen. Pl. iii. 1061 
(incl. ASTHROCH ETE, Nees, Benth. et Hook. f., 1. c. 1062). 
Spikelets with 5-7 glumes, each perfecting 1-3 nuts. Glumes sub- 
distichous ; 3 lowest empty, fourth containing a bisexual nut-bearing 
flower, fifth inserted close above the fourth, uppermost sterile. Hypo- 
gynous bristles 6 or 3, long. Style linear, long, with 3 linear branches, 
at the base continuous with the nut, persistent. Nut oblong or oblong- 
ellipsoid, trigonous, at the top pyramidal.—Leaves evolute. Inflor- 
escence paniculate, not umbelled. 
Species 12, in the Southern Hemisphere, America, Africa and Australia. 
This genus differs from Schwnus only by the lowest nut-bearing glume having 
the next glume close over it, not separated by an elongate curved joint of the rhachilla 
as is the case in Schenus. 
1. ©. Emini, (. B. Clarke. Glabrous. Rhizome short, rather 
slender. Stems 1-2 ft. Jong. Leaves up to 3 the length of the stem, 
jz in. broad. Panicle 6-12 in. long; lower peduncles axillary carry- 
ing oblong panicles of many brown spikelets close together. Spikelets 
sin. long, of 5 glumes. Glumes oblong, hardly acute, the 3 lowest 
empty, the fourth containing a bisexual perfect flower, the fifth smaller 
and sterile. Hypogynous bristles 6, scabrid with upward-pointing 
barbs, the 3 inner (petals) as long as the nut, the 3 outer (sepals) twice 
aslong. Stamens 3, anticous. Nut small, } the length of the glume, 
hardly at all scabrid, obscurely reticulated.—Oreograstis Hmini, K. 
Schum. in Engl. Pfl. Ost-Afr. C. 127. 
Nile Land. British East Africa: Ruwenzori, 10,000 ft., Stuhlmann, 2439! 
This, as above interpreted, differs little from C. Aubertii, Nees, a Bourbon 
Plant ; but the description (of the same material) by Dr. K. Schumann differs con- 
siderably. 
18. SCHGENUS, Linn. ; Benth. et Hook. f. Gen. PI. iii. 1062. 
Spikelets perfecting 1 or few nuts. Glumes subdistichous; 5 
lowest empty, fourth containing a bisexual nut-bearing flower, the 
thachilla elongated and curved before the insertion of the fifth glume ; 
Uppermost glumes reduced. Hypogynous bristles various or 0. Style 
near, long, with 3 linear branches. Nut small, obovoid, trigonous, at 
the top truncate or pyramidal.—Inflorescence panicled, corymbose or 
Subcapitate, not umbellate.
