ENUMERATION OF PHILIPPINE LEGUMINOSAE. 
9 
timbers are narra, corresponding to the padouk of India, from Ptero- 
carpus indicus Willd., and P. echinaius Pers. ; acle, from Albizzia acle 
(Blanco) Merr. ; supa, from Sindora supa Merr. ; ipil, from Intsia hi jug a 
(Colebr.) 0. Ivtz. ; tindalo, from Pahudia rhomboidea (Blanco) Prain; 
banuyo, from Wallaceodendron celebicum Koord. ; batete from Kingio- 
dendron alternifolium (Elm.) Merr. & Bolfe, while many other species 
yield timber used locally for different purposes. Shade-trees and various 
ornamental plants are represented by Enterolobium saman (Jacq.) 
Prain, Albizzia lebbeck (L.) Benth., Delonix regia (Boj.) Raf., Cassia 
siamea Lam., Peltophorum inerme (Roxb.) Naves, Sesbania grandiflora 
(L.) Benth., Caesalpinia pulcherrima (L.) Sw., Bauhinia tomentosa L., 
B. acuminata L., B. monandra Kurz, Erythrina indica Lam., and others. 
Plants cultivated for food are Phaseolus lunatus L., P. radiatus L., 
Vigna sinensis Endl., Arachis hypogea L., Pisum sativum L., Canavalia 
gladiata DC., Cajanus indicus Spreng., Pachyrrhizus erosus TJrban, Dol- 
ichos lablab L., Psopliocarpus tetragonolobus (L.) DC., Tamarindus 
indica L., Sesbania grandiflora (L.) Pers., Pithecolobium dulce Benth., 
also yielding a valuable tanbark, and Inocarpus edulis Forst. Plants 
yielding dyes are represented by Caesalpinia sappan L., Indigofera suf- 
fruticosa Mill., and I. tinctoria L. Substitutes for soap, used in bathing, 
washing the hair, etc., are derived from Albizzia saponaria (Lour.) Bl., 
A. acle (Blanco) Merr., Entada scandens Benth., and E. parvifolia Merr. 
Various species of Derris are utilized for the purpose of stupefying fish. 
Extensively used hedge-plants are Gliricidia sepium (Jacq.) Steud., and 
to some extent Leucaena glauca Benth., the wood of the former also 
highly prized for making charcoal. Gliricidia and Erythrina indica 
Lam., are more or less utilized as shade trees in various plantations. A 
considerable number of species are utilized by the natives in their 
materia medica, while a great number are employed for various minor 
purposes. 
I am indebted to Dr. I. Urban and to Dr. H. Harms of the Kgl. Bot. Garten, 
Berlin; to Dr. H. Leeomte, of the Museum of Natural History, Paris; to B. 
Daydon Jackson, Esq., Secretary of the Linnean Society, London; to M. C. De- 
Candolle, Geneva, and to Dr. J. N. Bose, of the United States National Herbarium, 
Washington, for various comparisons of Philippine material with type specimens 
in a number of cases, and especially to Dr. D. Prain, Director of the Boyal Botanic 
Gardens, Kew, for numerous identifications, comparisons, and critical notes 
supplied me during the incumbency of his present position, and previous to his 
appointment to Kew when he was Director of the Boyal Botanic Gardens at 
Calcutta. 
In the following keys to the genera, that part dealing with the Papilionatae 
has been made purely artificial in many respects. In the construction of the 
keys to both genera and species suggestions have been taken from the previously 
published works of various authors, modified by the forms dealt with in the 
following enumeration. In these keys only Philippine representatives have been 
taken into consideration.
