 staminate flowers: Province of Abra, Tue, For. Bur. 14582 Darling, February, 

 1909, sterile, altitude 1,000 m. Known to the Igorots in Abra as Balcar/. 



A species manifestly allied to the Asiatic Acer laevigatuiu Wall., but witli 

 different leaves which are usually broad and rounded at the base, and witii -1- 

 merous staminate flowers. It is quite different from the only other species of the 

 genus known from the Philippines, A. philippinum Merr., that species having the 

 leaves very glaucous beneath, and the staminate inflorescence racemose. The 

 latter species is a shrub or small tree, while the present one is a large tree. 



A third species is possibly represented l)y sterile material. For. Bur. 10948
