Endemic. 



I have followed Clarke in making this a distinct species ; it is, perhaps, 

 a variety of the Malayan T. tetrandra, Bl. The leaves dry black.

[//. zeylanicum. Lam., is based on H. curassaviaan, var. j8, zeylanicum, 

 Burm. Fl. Ind. 41, which was collected at Tuticorin, S. India, by Garcin. 

 It is figured by Burman, Fl. Ind. t. 16, f. 2, which figure might well 

 represent //. /a«/Vz//a/«w. Wight refers it to his Tournefortia zeylanica; 

 but from his plates (Ic. t. 892 and 111. t. 170 B) that would seem to be 

 quite a different plant. He is followed by the Fl. B. Ind. The specific 

 name should, however, in that case be abandoned, as this latter plant 

 does not occur in Ceylon.]
