 copious, usually in close single rows in the lobes. Hk. tip. 4. p. 61. 



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

 of which Presl and others make several species. Sometimes the venation is quite free, 

 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 fugacious.

 mice and segments ample. Sp. 201-224.
