Socotra. Very common. B.S.C. mi. 117, 566. Schweinf. n. 463.

Quite a distinct form amongst the non-capitate species of the genus. It is 

 a rather prettily-flowered species.

Socotra. Near Tamarida on the hill slopes. B.C.S. n. 577. 



Distrib. Endemic. 



A species easily distinguished from the preceding one by its somewhat 

 creeping, scarcely-branched habit, its dense pubescence, more shortly-stalked 

 leaves, flowers on stouter peduncles, and the smaller bracteoles enclosing 

 Mowers the corolla of which is fully one-half larger. The form and arrangement 

 of the bracteoles allow of little doubt as to its correct position in this genus.
