SORGHUM Moench, Meth. (1794) 207. 
The recent trend has been to conserve Holcus L. 
for Holeus lanatus 1. and to place H. halepensis L. 
and H. Sorghum 1. in Sorghum Moench. 
In doing this, two new combinations are made 
necessary, namely: 
Sorghum vulgare Pers. var. caffrorum 
( Thunb.) Hubbard & Rehder, comb. nov. 
Holcus Caffrorum Thunberg, Prodr. Pl. Cap. 1 
(1794) 20. 
Sorghum Caffrorum Beauvois, Agrost. (1812) 181, 
164, 178. 
Holeus Sorghum W. var. caffrorum L. H. Bailey, 
Gentes Herb. 1 (1923) 1838. 
Sorghum vulgare 1. var. Durra ( Forsh. ) Hub- 
bard & Rehder, comb, nov. 
Holeus Durra Forskal, Fl. Aegypt.-Arab. (1775) 
174. 
Andropogon Sorghum Brot. subsp. sativus Hack. 
[var.] Durra Haeckel in De Candolle, Monogr. 
Phan. 6 (1889) 516. 
Sorghum Durra Stapf in Prain, Fl. Trop. Afr. 9 
(1917) 129. 
Holeus Sorghum WL. var. Durra 1. H. Bailey, 
Gentes Herb. 1 (1928) 132. 
The synonymy of the varieties of Sorghum vulgare 
is very involved and the identity of many varietal names
