Widely distributed through the Mediterranean Ptegion from the Canaries and 
Southern Europe to Syria, also in South Africa and in Tropical Arabia. 
Several subvarieties have been distinguished; of these the following are recorded 
from Eritrea by Hackel, l.c., and by Chiovenda,l.c. 281: — 1. genuinus, Hack., with 
glabrous spikelets ; 2. pubescens. Pari., with hairy spikelets ; 3, dasystachyus, Hack, 
l.c. 462, with still more hairy spikelets ; 4, luxurians, Chiov., a robust state 
with 3-4-nate racemes and glabrous spikelets; and 5 ,alpina, Chiov., a dwarfed 
condition, hairy all over, with short racemes and small seaberulous spikelets, 
3|-4 lin. long. It seems to me that none of these forms, with the possible 
exception of the last, are more than individual variations or ecological states.
