This curious species agrees very nearly with O. Blumei ; hut 

 it is considerably larger, and the thick nearly terete nerve is co- 

 vered with shorter papiUse, 



Besides the above, two other intimately allied species have 

 been sent from Java. 



O. iiisriDULUM, sp. n. Humilis; folia a basi erecta, oblonga, celhdis
