Menyharth, 1044, has spikelets which are unusually hairy, approaching in this 
respect those of S. osthiopicum. 
Specimens collected in Italian Somaliland at Buahere ( Riva, 461) and Mil- 
Mil ( Riva , 1166) and enumerated by Chiovenda (Ann. Istit. Bot. Roma, vii. 
60) as Andropogon Sorghum, var. halepensis, subvar. genuinus, belong probably 
either to this species or to S. verticilliflorum. The same applies to specimens, 
collected by Carvalho in “ Zambesia 55 (A. Sorghum, var. effusus, Hack, in Bolet. 
Soc. Brot. vi. 142).
