ENUMERATION OF PHILIPPINE LEGUMINOSAE. 
7 
Australian types are Acacia confusa, mentioned above, and Clianthus 
binnendyckianus Kurz, the genus with one species in Mindanao, Polillo, 
and Celebes, and two in Australia. An indication of a probable line of 
migration from Australia through the Philippines and intervening islands 
to southeastern Asia, or vice versa is represented by Glycine tomentosa 
Benth., Queensland, Luzon, and China, and Pycnospora nervosa W. & A., 
Australia, Philippines (common and widely distributed), China, and 
India, but not known from Malaya, while the genus Erythrophloeum has 
one species in Australia, one in the Philippines, one in China, and is, so 
far as is known at present, wanting in Malaya and India, but has about 
five species in Madagascar and tropical Africa. 
Hew Guinea and the Philippines have in common Rhynchosia calos- 
perma Warb. (also in the Aru Islands and Bismarck Archipelago), and the 
genus Macropsychanthus, with one species in Hew Guinea, and two in 
Mindanao. The Celebes alliance is stronger, with the monotypic genus 
Wallaceodendron, Dalbergia minahassae Koord., Pithecolobium subac- 
uturn Benth., Clianthus binnendyckianus Kurz, and Pterocarpus echi - 
natus Pers. (also in Salayer), while Pueraria warburgii Perk., of the 
southern Philippines, is represented in Celebes by an identical, or closely 
allied form. Special cases of distribution from other parts of Malaya 
are few.' Pithecolobium prainianum Merr. appears to be known only 
from the Philippines, Borneo, and Java, Cassia divaricata Hees & Bl., 
Luzon and Java, Mezoneurum latisiliquum Merr., and M. pubescens 
Desf., Timor and the Philippines, as well as the typical form of Parkia 
timoriana Merr. Spatholobus gyrocarpus Benth. is known only from 
Luzon, Penang, and the Malay Peninsula (Perak), and Desmodium 
ovalifolium Wall, from Luzon, Sumatra, and Penang. 
A notable characteristic of the Philippine flora as a whole, is the high 
percentage of endemic species, but endemism is not particularly developed 
in Leguminosae. Two genera, Monarthrocarpus Merr., and Luzonia 
Elm., both monotypic, and the following 82 species, are, so far as is known 
at present, confined to the Philippines : Pithecolobium scutiferum Benth., 
P. pauciflorum Benth., P. mindanaense Merr., P. platycarpum Merr., 
Albizzia scandens Merr., A. acle Merr., Adenanthera intermedia Merr., 
Entada parvifolia Merr., Erythrophloeum densiflorum Merr., Cynometra 
inaequifolia A. Gray, C. warburgii Harms, C. luzoniensis Merr., C. sim- 
plicifolia Harms, Kingiodendron alternifolium Merr. & Bolfe, Sindora 
supa Merr., Intsia acuminata Merr., Pahudia rhomboidea Prain, Crudia 
blancoi Eolfe, C. subsimplicifolia Merr., Bauhinia dolichocalyx Mem, 
B. leptopus Perk., B. subglabra Merr., B. whitfordii Elm., B. cumingiana 
F.-Vill., B. nymphaeifolia Perk., B. perkinsiae Merr., B. aherniana Perk., 
B. antipolana Perk., B. merrilliana Perk., B. pinchotiana Perk., B. war- 
burgii Perk., Pterolobium membranulaceum Merr., Mezoneurum mindo- 
rense Merr., Ormpsia paniculata Merr., 0. calavensis Azaola, Crotalaria
