Near Serissa fcetida 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. fcetida, 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 

 "PL David." p. 154, the plant 

 is " tres voisine du S. fcetida 

 L., dont elle differe seule- 

 ment par sa corolle doux fois 

 plus petite et dont le tube 

 depasse peu les dents calici- 

 nales que sont lanceoles- 

 subulees et souvent ciliees sur 

 les bords ; dans le S. fcetida, 

 les dents du calice sont presque 

 deux fois plus courtes que le 

 tube de la corolle ; les deux 

 especes mieux connues devront Fig. 19, Litosanthes gradlis HAYATA; a, a flower; 



probablement etre reunies. b ' corolla ' ^ from back: c ' portion of corolla ' "^ 



from within ; d, ovary and style, which is 4-lobed at 



Varie a feuilles largement the apex; e, vertical section of the ovary with a disc.
