Also on the Egyptian coast, in Socotra, on the Arabian coast and in Scinde. 

 Miiller records this species as collected by Boivin in the Comoros, but the original 

 field-note accompanying the only gathering of the plant by Boivin gives the locality 

 as Berbera in Somaliland. This species assumes two somewhat distinct forms, 



(a) with larger leaves, more obtusely lobed, met with everywhere within our ai'ea, and 



(b) with rather smaller acutely lobed leaves, more frequently met with from Suakin 

 southwards. The second form, which includes the two varieties suggested by 

 Schweinfurth, is, howevei*, connected, with the first by too many intermediates to 

 admit of its being accorded sepai'ate recognition.
