 This differs from I. appendictUata, Bl, in having narrower leaflets, with ranch 

 shorter petioles and more numeroas nerves which are quite horizontal. The leaves 

 are moreover quite glabrous and shining. The Perak specimens from which the

 received at the Calcutta Hei'barium from the Buitenzorg Botanic Garden.
