f. lobatum f. n. (I. coll., no 21). 



This species seems to be variable. The present specimen from 

 Cheng-tu has its frond somewhat pinnately lobed towards the base. In 

 some specimen the lower lobes are much elongated so that the frond is 

 nearly triangular in outline. Moreover, the lowest lobe is sometimes 

 lobed again. The frond is entire in the type of the species.
