Saccharum violaceum Tussac, Fl. Antill. 1: 160. pl. 25. 1808. 
Jamaica. 
Gigantic perennial with broad leaves, the overlapping sheaths 
falling from the short-jointed lower part of the culms, the great plumy 
panicles pinkish silvery; forming seed sparingly (fig. 345). 
Cultivated in Tropics and Subtropics of both hemispheres. The 
West Indian specimens in herbaria are probably all from cultivated 
plants. The Spanish name is ‘‘cafia de azticar.”” Called in Haiti 
‘“‘canne a sucre.”’ 
SACCHARUM CILIARE Anderss., Ofv. Svensk. Vet. Akad. Férh. 12:

108. ERIOCHRYSIS Beauv., Ess. Agrost. 8. pl. 4 f. 11. 1812 
Spikelets awnless, the sessile spikelets perfect, the pedicellate spike- 
lets pistillate, smaller but fruitful, readily falling, the rachis rather 
tardily disjointing; racemes short, crowded in a narrow, dense, silky 
interrupted spikelike panicle. Erect perennials with yellow or brown 
compact woolly inflorescence.

Spikelets all alike, in pairs along a slender axis, one sessile, the

rachis joint and pedicel falling attached to the sessile spikelet; glumes 
coriaceous, equal, usually copiously clothed, at least at the base, 
with long silky spreading hairs; sterile lemma thin and hyaline; 
fertile lemma hyaline, the midnerve extending into a slender awn;
