This is the most common and widely distributed species of the genus in the 

 Philippines, being somewhat variable, and its synonomy is rather complicated, 

 due primarily to Blanco's imperfect descriptions, and to various later inter- 

 pretations of these. The leaves are bi- and tripinnate, frequently on the same 

 specimen, and the flowers vary in size from 2.5 to 3 cm in length, but on all the 

 specimens cited above, both under the species and the variety, the flowers are 

 uniformly described by the collectors, as far as the field notes show, as pink or 

 pale purple and marked with yellow inside. 



I have adopted the first valid specific name available, taken from Millingtonia 

 pinnata Blanco, although so far as I have observed, and in the large series of 

 specimens examined, the leaves are never simply pinnate. It is universally known 

 to the natives as Banaibanai, a name normally applied to no other species, other 

 than the following one, and with the exception of the discrepancy as to leaves, 

 Blanco's description applies very closely. The species is very abundant in the 

 regions from which Blanco received most of his material. The disposition of 

 Blanco's Millingtonia quadripinnata necessitated careful consideration, but I have 

 here reduced it to Radermachera pinnata (Blanco) Seem., although in this I 

 am at variance with both Seemann and Rolfe, wlio liave previously worked over 

 the Philippine species of this genus. Knowing thoroughly the flora of the region 

 about Manila, and the contigvious provinces, it does not seem probable that this 

 species, if distinct from R. pinnata, as considered by Blanco, should have escaped 

 our notice, but up to the present time there is nothing in our herbarium to 

 which Blanco's description applies so well as to the material here considered to 

 represent Radermachera pinnata. It seems rather curious that Blanco should 

 have described it under two different names, neither of whicli apply well to 

 the species, for none of the above specimens have simply pinnate leaves, and
