The species is comraou in northeru Africa and W. Asia, extending from the Cape Je Jer 

 Islands to AfFghamstan. I can find no difference whatever in the Australian specimen, ex 

 cept that the nuts are rather larger, but their size is variable in the African specimens. 



4. H. asperrlmum, R. Br. Prod. 493. A perennial with erect or 

 ascending stems of 1 to If ft., the branches and foliage very scabrous and 

 spnnk ed with rigid spreading hairs. Leaves shortly petiolate, oblong or 

 lanceolate, obtuse, with undulate revolute margins but not very nigo*'^; ^

 but undulate when young, green on both sides, the principal veins very pro- 

 minent underneath^ f to 1| in. long. Spikes once-forked or rarely simple, 

 hirsute, without bracts. Calvx-segnients lanceolate, hirsute, about 1 line
