THE GENUS RADERMACHERA HASSK IN THE PHILIPPINES.

Manila, P. /.) 
The Philippine history of this genus begins with the publication of 
Blanco’s “Flora cle Filipinas” in 1837, in which two species are inade- 
quately described, Millingtonia pinnata Blanco and Millingtonia quadri- 
pinnata Blanco. The descriptions of both are imperfect, and both species 
have been variously interpreted by later authors. The descriptions are 
repeated in the second and third editions of Blanco’s work, Without change 
of name. In 1861, Bureau described Radermachera banaibana in Aclan- 
sonia 2:194, based on a specimen in the Paris herbarium collected at 
Calauan, Province of Laguna, Luzon, by Gallery. This species is ma- 
nifestly the same as the one described by Blanco as Millingtonia pin- 
nata and was so considered by Seemann in his Revision of the Natural 
Order Bignoniaceae, 1 where Blanco’s Millingtonia pinnata is transferred 
to Radermachera as R. pinnata (Blanco) Seem., Bureau’s Rader machera 
banaibana being reduced as a synonym. At the same time Seemann also 
transferred Blanco’s Millingtonia quadripinnata to Radermachera, as R. 
quadripinna, and referred to it a specimen collected in the Philippines by 
Cuming (no. 996). In 1883, F.-Villar 2 transferred Blanco’s two species 
of Millingtonia to Stereospermum, as S. pinnatum and 8. quadripinna- 
tum, while Naves figured a plant that he identified with Millingtonia 
quadripinnata Blanco in the third edition of Blanco’s Flora de Filipinas, 
t. 252. In this same year Vidal 3 also figured a plant that he identified 
as Stereospermum quadripinnatum F.-Vill., which although poorly and 
imperfectly drawn, is, I am confident, identical with the plant determined 
by F.-Villar as Stereospermum quadripinnatum , and which, whether or 
not it -is Blanco’s Millingtonia quadripinnata, is certainly the plant he 
described as M. pinnata. 
In 1884, Rolf e 4 considered the Philippine species of Stereosperm um ,
