(Sorghum vulgare Pers.) 

 From Mpwapwa, German East Africa. Presented by Mr. W. Sperling, Kaiser- 

 liche Bezirksiimtmann. Received April 4, 1912. 

 This plant, which has been listed in previous numbers of these inventories as Andro- 

 pogon sorghum (L.) Brot., and is listed in the Index Kewensis as Sorghum vulgare 

 Pers., has been identified as the type of the genus Holcus by Mr. A. S. Hitchcock, who 

 says (Grasses of Cuba, Contributions from U. S. National Herbarium, vol. 12, pt. 6, p. 195, 

 1909): ''Holcus sorghum L. must be considered the type of the genus Holcus, since it 

 is the most important economic species of the genus, and, further, since, in the fifth 

 edition of his Genera Plantarum, Linnaeus refers to the genus Sorgum Mich [eli] as a 

 synonym of Holcus." It is therefore necessary to use this original Linnaean name for 

 the sorghum. 



"This seed is very interesting because it is apparently different from anything that 

 I have had previously from this region. It is apparently a sorgo, or sweet sorghum. 

 Its relationship can be ascertained only by growing it, but apparently it is related to 

 the Red Amber." (Carleton R. Ball.)

 farmer here and have not been grown at our experimental stations." (Stockdale.)
