ENUMERATION OF PHILIPPINE LEGUMINOSAE. 7 



Australian types are Acacia confusa, mentioned above, and Cliantlius 

 hinncndychianus Knrz, the genus ^yith one species in Mindanao, Polillo, 

 and Celebes, and two in Australia. An indicat>ion 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 Fycnospora nervosa W. & A., 

 Australia, Philippines (common and widely distributed), China, and 

 India, but not known fi'om Malaya, while the genus ErytJirophloeum 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 a1)out 

 five species in Madagascar and tropical Africa. 



New Guinea and the Philippines have in common Rhynchosia calos- 

 pcrnia Warb. (also in the Am Islands and Bismarck Archipelago), and the 

 genus Macropsychanthus, with one species in ISTew Guinea, and two in 

 Mindanao. The Celebes alliance is stronger, with the monotypic genus 

 Wallaceodcficlron, Dalhergia minahassae Koord., Pithecolohium stihac- 

 utum Benth., Cliantlius binnendyclcianus Kurz, and Pterocarpus echi- 

 natus Pers. (also in Salayer)^ while Pueraria warhurgii 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. Pithecolohium prainianum Merr. appears to be known only 

 from the Philippines, Borneo, and,. Java, Cassia divaricata N'ees & 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. Spatliolohus gyrocarpus Benth. is known only from 

 Luzon, Penang, and the Malay Peninsula (Perak), and Desmodvum 

 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, Monarthrocarpu^ Merr., and Luzonia 

 Elm., both monotypic, and the following 82 species, are, so far as is known 

 at present, confined to the Philippines : Pithecolohium scutiferum Benth., 

 P. pauciflorum Benth., P. mindanaense Merr., P. platycarpum Merr., 

 Alhizzia scandens Merr., A. acle Merr., Adenanthera intet'med'ia Merr., 

 Entada parvifolia Merr., Erythropliloeum densiflorum Merr., Cynometra 

 inaequifolia A. Gray, C. ivarhurgii Harms, C. luzoniensis Merr., C. sim- 

 plicifolia Harms, Kingiodendron alternifolium Merr. & Eolfe, Sindora 

 supa Merr., Intsia acuminata Merr., Pahudia rhomhoidea Praiu, Crudia 

 hlancoi Rolfe, C. suhsimplicifolia Merr.-, Bauhinia dolichocalyx Merr., 

 B. leptopus Perk., B. suhglahra Merr., B. whitfordii Elm., B. cumingiana 

 P.-Vill., B. nymphacifolia Perk., B. perhinsiae Merr., B. aherniana Perk., 

 B. antipolana Perk., B. merrilliana Perk., B. pinchotiana Perk., B. war- 

 hurgii Perk., Ptcrolohium memhranulaceum Merr., Mezoneurum mindo- 

 rensc Merr., Ormosia paniculata MeiT., 0. calavensis Azaola, Crotalaria
