ENUMERATION OF PHILIPPINE LEGL'MINOSAE. 29 



Luzon. Province of Union, Elmer 5689. 



Acacia philippinaruin Benth. was based on two specimens, one of which is 

 referable to A. rugata (A. concinna) , to which Benthain himself reduced the 

 species, and the other is Acacia caesia Willd. 



Apparently not common in the Philippines; India to southern China and the 

 Malay Archipelago.

Widely distributed in India and Ceylon, extending to Java and Sumatra, but 

 not reported from the Malay Peninsula or from southern China. The specific name 

 caesia has only page priority over intsia and has been here adopted following 

 Bentham and Trimen. Trimen, I. c, states that Acacia intsia can not be distin- 

 guished from A. caesia, even as a variety.

Acacia pennata (L.) Willd, as interpreted by recent botanists, contains several 

 rather distinct forms, three of which are found in the Philippines. I am not 

 at all sure that the specimens above referred to the species represent the typical 

 form. As here interpreted, it is characterized by its small and raised basal 

 petiolar gland, with few small glands on the rachis, and its axillary, fascicled or 

 solitary heads, which are sometimes arranged in short racemes. The var. 

 arrophula is characterized by a large basal petiolar gland, with few small ones on 

 the upper part of the rachis, while the var. pluricapitata is distinguished by its 

 heads being arranged in ample terminal panicles, small, raised basal petiolar 

 gland, and numerous small glands on the rachis, one between every pair of pinnae,
