with one species in Sikkim and one in Java; the other half is Philippine. 
Spp. 19, n. 34-52. 
The calius at the base of the standard is very uniform and characteristic of 
the section, It may he explained as an &-shaped ridge connecting the edge 
of the claw below with the margin of the blade above. 
It is rather an isolated and naturally compact section, with a tendency 
towards Ofosema, but no intermediates. M. decipiens closely resembles 
Pongamia glabra. Prain's notes on the group in Journ. As. Soc. Beng. lxvi. 
п. 362 (1897) should be read.
