nate; lateral nerves 20 to 25 on each side of the midrib, slender, 
distinct on both surfaces, the secondary veins not parallel, re- 
ticulations distinct; petioles 3 to 3.5 cm long. Panicles quite

A species similar to Buchanania sessilifolia Blume (B. acuminata 
Turcz.), from which it differs in its much more numerous lateral nerves, 
and entirely glabrous leaves and panicles. The material was distributed 
as Buchanania arborescens Blume, but it is quite different from that 
species and not closely allied to it. 
BUCHANANIA RETICULATA Elm. Leaf!. Philip. Bot. 4 (1912) 1499. 
This is typical Mangifera altissima Blanco, and must be reduced to 
Blanco’s species. The type is Elmer 12331 from the Island of Sibuyan.

458; Miq. FI. Ind. Bat. I 1 (1855) ‘366= Buchanania arborescens Blume. 
This species was considered by Miquel as a true Prunus, but he mani- 
festly saw no specimens. A cotype of the species, received from the 
Museum of Natural History, Paris, is in the Herbarium of the Bureau 
of Science. The specimen is with fruits, and is typical Buchanania arbo- 
rescens Blume.
