Ng Chi Leng, McClure 8559, December 20, 1921. In forested 
ravines along streams. 
A species well characterized by being entirely glabrous except - 
the flowers (buds) and fruits, and in its rostrate fruits. It 
resembles the Philippine Sideroxylon villamilii Merr. in its vege- 
tative characters but has very different fruits.
