1. SHOREA BALANGERAN (Korth.) Dyer. 



Our material credited to this species resembles very closely that shown 

 in Korthals' original figure [Verh. Nat. Gesch. Bot. (1848) t. 7] in leaf 

 and flower characters, except that there are more than fifteen stamens, 

 in some cases about thirty, and the appendage to the connective is ciliate. 

 The style is also shorter than that shown in the figure. I have not seen 

 the type of Shorea balangeran and thus do not feel that it is desirable to 

 describe our form as a new species. Much of our material is sterile. The 

 fruit has not yet been collected.
