32 SORGHUM. 



three of the larger varieties introduced by Mr. Wray may be con- 

 founded under these several names, but, at the present, the identity 

 of each has not been established. The compact heads of the African 

 varieties is a marked feature ; but that is not a characteristic of those 

 Avhich are valuable for sugar, since two of these, Plates V and VI, which 

 are called AmalDele, are practically worthless for sugar, although, like 

 the other African varieties (Imphees), they have compact panicles or 

 seed heads. The two varieties from Northern India have loose, waving 

 heads, but are very valuable for sugar, as the analysis, page 101, will 

 show. The presence of these two distinct classes from South Africa, 

 with their wide difference in sugar content, is highly interesting, es- 

 pecially in view of their being recognized as belonging to distinct 

 families. It will be seen that the per cent of sugar in the juice of the 

 two Amabeles averages 4.90, while in the seventeen Imphee varieties 

 it averages 11.82 per cent.
