 Ridley 2735, 9166. 



Ridley's specimen from Upper Bukit Mandai, Singapore, has darlc rough 

 branchlets, smaller leaves with closer main-nerves and less crowded cymes, but does 

 not seem otherwise to differ, at any rate not sufficiently to warrant its being made a 

 variety. 



L. Grijjithii is an india-rubber producer, and the product is said to be good, very 

 probably as good as that of the neighbouring L. elasticus, Becc. ' Nelle foreste di 

 Borneo,' pp. 358, o6'2, fig. 59, and Hook. Ic. PI. t. 2733.
