xiii, c, 3 Foxworthy: Philippine Dipterocarpaceae, II 181 



placed provisionally under Dipterocarpus speciosus Brandis: For. Bur. 

 10711 Curran, 1908 (with old fruit), For. Bur. 22646 Alvarez, 1911, For. 

 Bur. 21737 Penas, Soriano & Abellanosa, 1914, For. Bur. 21216 Alvarez, 

 1914. All of these specimens were collected in Camarines Province and 

 all were sterile, except Curran's specimen, which had fruit picked up 

 under the tree. These all have leaves very much larger and with a larger 

 number of secondary veins than those of the type. They may well rep- 

 resent another species; but, for the present, it seems well to place them 

 under this. 



Villamil UU, collected in the southeastern part of British North Borneo 

 in 1915, seems to belong with the form just mentioned.
