The Philippine liistoiy of this genus begins with the publication of 

 Blanco's "Flora do Filipinas" in 1837, in which two species are inade- 

 quatel}' described, Milliiujtonia pittnala Blanco and Millinglonia ([uadri- 

 plnnata Blanco. The descriptions of both are imperfect, and both species 

 have been variously interpreted l)y later authors. The descriptions are 

 repeated, in the second and third editions of Blanco's work, without change 

 of name. In 1861, Bureau described Badermacliera hanaihana in Adan- 

 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 Millmgtonia pin- 

 nata and was so considered by Seemann in his Revision of the Natural 

 Order Bignoniaceae,^ where Blanco's Millingtonia pinnata is transferred 

 to RadcrmacJiera as E. pinnata (Blanco) Seem., Bureau's Radermacliera 

 hanaihana 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 - transferred Blanco's two species 

 of Millingtonia to Stereospermum, as 8. pinnatum and S. 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 •" 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.-Yillar as Stereospernium quadripinnatum. and which, whether or 

 not it is Blanco's Millingtonia quadripinnata. is certainly the plant he 

 described as M. pinnata. 



In 1884, Polfe ** considered the Philippine species of Stcreospermum,
