LUZON, Province of Bataan, Mount Mariveles, For. Bur. 0,'olf Curran, Feb- 

 ruary, 1907, with nearly mature fruit, in forests at an altitude of about 550 m 

 (type) : Province of Benguet, Mount Ugo, Bur. Sci. 5708 Ramos, December, 1!)0S, 

 -laminate flowers: Province of Abra, Tue, For. Bur. 1 '/oSJ Darling, February, 

 1909, sterile, altitude 1,000 m. Known to the igorots in Abra as Baleag. 



A species manifestly allied to the Asiatic Acer laeriijotiim Wall., hut with 

 different leaves which are usually broad and rounded a! I he base. an. I with 4- 

 Bteroua •taminate flowers. Jt is quite different from the only other species of the 

 genua known from the Philippines, A. pkiUppimvm Mem, 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 by sterile material. For. Bur. lufi'/S 

 Curran, Mount Data, District of Lepanto. Luzon, the young leaves being densely 

 tomentose beneath.

 remotely resemble. T., Malaligas.

 to .\filiosma lancifolia- Hook, f., of the Malay Peninsula, but apparently sufficiently 

 distinct.
