Type specimen 12552 in flower and 12318 in fruit, A. 
D. E. Elmer, Magallanes (Mt. Giting-giting), Province of 
Capiz, Island of Sibuyan, April and May respectively, 1910. 
This small slender tree was collected on wooded banks 
of the Pauala river at 750 feet, in red soil with a stony and 
gravelly subsoil, and along the Sinuban creek under similar 
conditions. The fruiting specimen was called ‘‘Leter’’ by the 
local Visayan. 
My number 12086 from the same locality is not quite 
typical. Superficially similar to S. stenophylla Merr. from 
Mindoro. Foliage similar to that of Pittosporum.
