Hab. N. India, Hong-Kong, Philippines, Malaooaa, Fiji, Samoa.— A variable plant

 and sometimes only the veinlets of contiguous groups are joined, and the lobes vary 

 from as broad as deep, when they are blunt and entire, to four times as broad as deep, 

 and deeply crenated. The involucre is very fugaoioas.
