Distrib. ore rare species confined to Northern Nigeria; it was 
discovered by Barter (No. 1223) in Yoruba and was subse- 
quently gathered by Dalziel (No. 405) in Sokoto Province. 
The flower-heads are borne on the stem quite close to the 
ground, the leafy shoots afterwards elongating and barren.

This is very probably Picris aseattis DC, Prodr. vii. 130, known 
only from an imperfect specimen collected by Leprieur in 
Selle, and not seen by the authors of the Flora of Tropical 
Africa. It was also gathered in the Katagum district by 
Dr. J. M. Dalziel (No. 392). The species is easily mistaken 
for P. abyssinica, Sch. Bip., from Abyssinia but the achenes 
in that species are not attenuated as in the Nigerian plant.
