 s. n.: Province of Tayabas, For. Bur. 10335 Curran: Province of Camarines, 

 Ahem 62. Celebes, Koorders, cultivated in the Botanical Garden, Buitenzorg, 

 Java. 



Native name (Tayabas), Tahid-labuyo, meaning cock's spiir, from the spines. 



A species allied to those of soutliern China; known only from Luzon and 

 Celebes. 



A second species is apparently represented by sterile material collected in Cebu 

 by Espinosa, For. Bur. 6488, locally known as Matagum. It difl'ers from G. rolfei 

 in having entire leaflets which are prominently and inequilaterally retuse at the 

 apex. 



The generic name is in lienor of Gleditsch, latinized and simplified Gleditsia; 

 Taubert prefers the spelling Gledilschia.

Endemic. 



Blanco's description is imperfect, and in some respects does not apply especially 

 well to the specimens here referred to it; I am confident, however, that the iden- 

 tification is correct.

Native names: Ariol del fuego; cahallero. The "fire tree" or "flamboyant." 



A native of Madagascar, now widely distributed in the tropics of the world 

 in cultivation; commonly cultivated in towns in the Philippines. 



Following strict rules, the proper generic name for this well-known and widely 

 distributed species is Delonix Raf., as the genus Poinciana Linn, was based solely 

 on what is now generally known as Caesalpinia pxdcherrima (L. ) Sw^ The genus 

 I'oinciana has page preference over Caesalpinia, and hence by strict interpretation 

 of the rules of nomenclature, those species now referred to Caesalpinia, generic 

 limits retained as defined by Benthara & Hooker, should be treated as Poinciana, 

 the genus Caesalpinia falling into synonymy. This extreme interpretation has 

 been followed by some recent botanists, but at the same time they have raised 

 some of the sections of Caesalpinia, as interpreted by Bentham & Hooker, and 

 by Taubert, to generic rank. It seems doubtful to me if any representative 

 botanical congress will sanction tlie transfer of Cnesttlpinia liodily to Poinciana,
