Culms robust, 0.6-1.5 m. high, erect. Sheaths terete, usually 

 shorter than tlie internodes; ligule round, firm, 1-3 mm. long; 

 blade narrowed more or less at the base, tlie longest 20-60 cm. 

 long, 1-7 cm. wide, flat, with undulate margins, the apex droop- 

 ing. Panicle variable, more or less drooping, exserted, rays mostly 

 in verticels of 4, rarely 2-6. Sessile spikelets variable; first glume 

 firm, more or less shining, margins involute, 5-9-11 -nerved; 

 second as long as the first, 3-7-nerved, keeled; third one-fourth 

 shorter, elliptical, oblong or oval, delicately 2-nerved; fourth half

Subspecies sativus Hackel, D. C. Monog. Phan. 6:505 (1889). 



Out of this subgenus Hackel, in his recent elaborate monograph 

 has made nine series, containing thirty-six varieties and twelve 

 subvarieties. Many of them are in cultivation in tropical regions. 



Some of the common names as we know them are: Guinea 

 Corn, Great Millet, Indian Millet, Durra or Doura, Im- 

 PHEE, Chinese Sugar-cane, Egyptian Kice-corn. 



The following is a description of the race known as ^' Amber 

 Cane." Culms 1-2 m. high, leaf -blades broad. Panicle erect 

 or included, rather compact, 20-30 cm. long, 6-10 cm. wide. 

 Spikelets when mature rouud-obovoid, 5 mm. long, the branches 

 and pedicels and base of spikelets short-hairy, awn abortive. The 

 2 outer glumes smootli, almost black, indistinctly many-nerved, 

 the first 11-13-nerved, the second 11-nerved, reddish, with hairy 

 maj-gins, very variable in size. Lodicules red, hairy at the apex, 

 truncate, very broad above, 0.7 mm. long. Pedicellate spikelets 5
