ENUMERATION OF PHILIPPINE LEGUMINOSAK. 55 



This species is the type of tlie genus Poinciana Linn., and is the only one 

 cited by him under this genus in the first edition of his "Species Plantarum." 

 According to strict priority Poinciana would be the proper generic name for the 

 species now placed in Caesalpinia. See page 52.

India to Indo-China, the Malay Peninsula and Archipelago; probably not a true 

 native of the Philippines, but introduced in ancient times.

I am unable to distinguish Caesalpinia benguetensis Elm. from the widely 

 distributed G. sepiaria Roxb. Mr. Elmer states that his species is distinguished by 

 its smaller leaves, obsolete stipules, and pods not beaked; the former character is 

 exceedingly variable, while my specimen of the type number has a single pod 

 bearing a 5 mm long beak, and the stipules, although smaller than in typical 

 Caesalpinia sepiaria, and early deciduous, are present. The stipules on Elmer 

 5888 are very distinct. The transfer to Mezoneurum was primarily due to a 

 suggestion made by myself, and apparently without additional study on the part 

 of Mr. Elmer. 



It correctly reduced, Reichardia ? decapetala Roth Nov. PI. Sp. (1821) 212; 

 DC. Prodr. 2 (1825) 484, supplies the earliest specific name for the species, as 

 Roxburgh's original reference to Caesalpinia sepiaria is a nomen nudum. 



India to southern China and Japan, south to Malaya; introduced in tropical 

 America, Australia, and Africa. 



EXCLUDED SPECIES. 



Caesalpinia mimosoides Lam.; F.-Vill. Nov. App. (1880) 69. A species of 

 India and Ceylon, not known from the Philippines, and doubtless admitted by 

 F. -Villar on an erroneous identification.
