33. C. flavidus, Retz. Obs. v.13. Annual, living about 3 months. 
Stems 2-8 in. long, tufted, sometimes rather stout but weak, obtusely 
trigonous (not acutely triquetrous). Leaves generally longer than the 
stem, often 4—} in. broad, weak. Umbel usually very compound, and 
denser than that of C. Haspan, when ripe yellow or finally blackening ; 
bracts usually overtopping the umbel, similar to the leaves. Stamen 
usually 1 (rarely 2). Nut plano-convex, when ripe marble white; 
otherwise as C’. Haspan.—Vahl, Enum. ii. 334; C. B. Clarke in Journ.

This plant is very unlike the typical large C. Haspan, but is difficult to separate 
from small tufts of C. Haspan flowering the first season. It may generally be dis- 
tinguished by the long leaves ani bracts which very rarely occur in C, Haspan. 
34. ©. podocarpus, Boeck. in Flora, 1879, 551. Glabrous. 
Rhizome seen } by is in., clothed by striate scales. Stems 10 in. long, 
tufted, slender, tough, obtusely trigonous. Leaves % the length of the 
stem, tin. broad. Umbel simple ; rays 2-4, up to 1} in. long ; bracts 3 
lowest suberect up to 4-8 in. long, similar to the leaves. Spikes of 3—7 
spikelets, ebracteate. Spikelets 2 by J; in., a little compressed, somewhat 
turgid, 8—12-flowered, variegated with red-purple. Glumes ovate, obtuse. 
tamens 3; anthers small, nearly square. Style, including the 3 
branches, shorter than the nut. Nut } the length of the glume, broad 
ellipsoid, trigonous but much flattened on the anterior angle, suddenly 
narrowed into a minute stalk, smooth, black.—C. B. Clarke in Durand
