Desmodium, Mucuna, etc.;, are distin^ished, yet the movement by some 

 botanists again to raise certain groups of species, in the above and other 

 genera, to generic rank, meets with comparatively little support. The 

 author is personally of the opinion that it vi'ould be more logical and 

 practically as convenient, to divide some of the larger genera into several 

 smaller ones, where the sections or subgenera are sharply defined as are 

 some of them in Cacsalpinia, Cassia, Desmodiuni, etc. For purposes of 

 comparison, however, generic limits as defined by Bentham and by 

 Taubert are retained in the present paper. 



Generic nomenclature in the present enumeration differs from that 

 of De Dalla Torre & Harms "Genera Siphonogamarunr' only in two 

 cases, these being the adoption of Delonix Eaf. for Caesalpinia auct., 

 non L., and Parosela Car. for Dalea L., for what are considered valid 

 reasons. 



The only previous attempt to enumerate all the species of this family 

 known in the Philippines was by F.-Villar,^ who credited to the Archi- 

 pelago 78 genera and 229 species. Of these, it has been necessary to 

 exclude 6 genera and about 35 species, as no material is extant by which 

 F.-Yillar^s identifications can be checked, and the excluded genera and 

 species have not been found in the Philippines by any preceding or suc- 

 ceeding botanists. ^ 



In the present enumeration 90 genera are considered. Of these, two, 

 Monarthrocarpus, described as new, and Luzonia, are monotypic and 

 endemic; the former allied to Desmodium §■ Podocarpium, and the lattei' 

 to Dioclea. Of the 90 genera included, 14, Enterolohkim, Leucaena, 

 Sclirankia, Mimosa, Prosop is, Tamarindus, Delonix, Medicago, Gliricidia, 

 Arachis, Pisum, Centrosema, Pachyrrliizus, a,nd Psophocarpus, are repre- 

 sented in the Philippines by introduced species only, while in other 

 genera, such as Cassia, Crotalaria, Desmodium, etc., there are many in- 

 troduced forms. 



The number of species recognized is 285, with several varieties, and 

 this list will doubtless be somewhat increased as exploration progresses. 

 Of these 285 species I consider the following 53 to have been introduced, 

 although most of them are now thoroughly naturalized and must be con- 

 sidered as constituents of the Philippine flora: Enicrolohium saman,* 

 Pithecololium dulce,* Albizzia lehbeck. Acacia farn-esiana,* Leucaena 

 glauca,* Scliranhia quadrivalvis,* 2limosa pudica* Prosopis vid<diana,* 

 Cynometra cauliflora, Tamarindus indica (prehistoric), Bauhinia tomenr 

 tosa, B. monandra,* Cassia fistula, C. glauca, C. tora, C. hirsuta,* C. 

 sophcra,* C. occidentalis,* C. alata,* C. siamea, Delonix regia, Caesalpinia 

 pulcherrima,* Crotalaria juncea, C. incana,* Medicago denticidata, M. 

 sativa, Trifolium pratense, T. hybridum, T. incarnatum, T. repens, Indi- 

 gofera suffruticosa,* Parosela glandulosa* Gliricidia scpiuin,* Sesbania
