The Philippine history of this gonus begins with the publication of 
Blanco's "Flora de Filipinas" in 1837, in which two species are inade- 
quatel}' described, MilJinglonia phinaia Blanco and MiUlngtonia quadrl- 
pinnata Blanco. The descriptions of both are imperfect, and both species 
have been variously inter])reted 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 Tladcrmaclicra hanaihana in Adan- 
sonia 2:194, baseil on a specimen in the Paris herbarium collected at 
Calauan, Province of Laguna, Taizou. by Gallery. This species is ma- 
nifestly the same as the one described by Blanco as MUJlngtonia pin- 
nata and was so considered bv Seemnnn in hi> "Revision of the Natural 
Order Bignoniaceae,^ where Blanco's MiUingionin pinnata is transferred 
to Radermachera as E. pinnata (Blanco) Seem., Bureau's Radennachera 
hanaihana being reduced as a synonym. At the same time Scemann also 
transferred Blanco's Millingfonia quadripinnata to Badcrmarhrra, as B. 
qiiadripinna, and referred to it a specimen collected in the Philippines by 
Cuming (no. 99(3). In 1883, F.-Yillar ^ transferred Blanco's two species 
of Millingtonia to Stereospermum, as S. pinnatuni and S, quadripinna- 
tum, while Xaves figured a plant that he identified with Millingtonia 
quadripinnata Blanco in the third edition of Blanco's Flora de Filipinas, 
i, 252. In this same year Yidal ^ also figured a plant that he identified 
as Stereospermum quadripinnalnm F.-Yill., which although poorly and 
imperfectly dra^^'n, is, I am Confident, identical with the plant determined 
by F.-Villar as Stereospermum quadripinnatum, and which, whether or 
not it is Blanco's MiUingtonia quadripinnata, is certainly the plant he 
described as M. pinnata. 
In 1884, Kolfe ^ considered the Philippine species of Stereospermum,
