Near Serissa foetida COMM., but differs from it by the very much shorter 

 corolla and the shorter oblong leaves, veins of which are not visible on the 

 under surface. In S. foetida, the veins of the leaves are visible on both surfaces. 

 Also near Serissa democritea BAILLON which I have never seen ; yet according 

 to a note given in FRANCHET'S
