teristic of the Malyan flora as a whole, are found in all, these 
numerous species also extend to other parts of Malaya and 
even to India, Polynesia etc., while very many other species 
common to the Phillippines and Malaya in general extend also 
to other parts of the tropics, even to tropical America and 
tropical Africa. There are very few species known to me that 
are confined to the area under discussion, the most striking of 
these being Chrysoglossum villosum Bl, Ficus pruniformis Bl., 
Croton argyratus Muell. Arg., Meliosma sumatrana Bl., and Labisia 
pumila Benth. & Hook. f. (also in Cochinchine), the latter as con- 
strued by the latest monographer comprising a monotypic genus. 
‘Phe Malay Peninsula and the Philippines show very few 
Species common and confined to both areas, although the flora’s of 
both regions are well known. Chief among these are Mapania 
Kurz Clarke, Cleistanthus laevis Hook. f., Alyxia lucida Wall., 
and BLrownlowia lanceolata Benth. (also in India), while Jsch- 
nostemma carnosum Merr & Rolfe, a monotypic genus, is known 
Only from the Malay Peninsula, the Philippines and Australia. 
A range of distribution from the Malay Peninsula through 
Borneo, in a few cases also Sumatra, and the Phillippines is 
represented by several very characteristic species, such as 
Dryopteris viscosa 0. K. (also Sumatra), Joinvillea malayana Ridl1., 
Pinus Merkusti De Vr. (also Sumatra, not reported from the Penin- 
Sula proper, but with doubt from the Shan States), Burmannia 
longifolia Bece., Podochilus «ytriophorus Schitr. Oroton ardisioides 
Hook. f., Mallotus anisophyllus Hook. £., Microdesmis casearifolia 
Planch., Dipterocarpus grandiflorus Blanco (also in Banka), and 
_ Simplocos adenophylla Wall. (represented in Mindoro by a variety). 
Two of these are not known to extend farther into the Philip- 
Pines than Mindoro, while four others extend only to Palawan. 
Sumatra and the Philippines show very few species in common 
and confined to the: two regions, the only one known to me 
at present being Ventildgo lucens Miq., a species of somewhat 
doubtful status. The paucity of types common to the two 
may be due to the fact that the flora of Sumatra is compa- 
ratively little known, although on the other hand, from the
