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 area, 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, however, connected wit! the first by too many intermediates to 
admit of its being accorded separate recognition.
