ENUMERATION OF PHILIPPINE LEGUMINOSAE, 56 
This species is the type of the 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.

Universally known in the Philippines as sappan or sappang, and sibucao, 
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 C. 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. Pl. 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.
