Warb., Koordersiodendron pinnatum Merr., a monotypic genus 
(also in Celebes), Ganophyllum obliguum Merv. (also in Australia), 
Medinilla Teysmanni Miq. (also in Celebes), Lpithema Benthami 
Clarke, Bikkia grandifora Reinw. (also in the Moluccas), and 
Dischidiopsis, a genus with two species, one in the Philippines 
and one in New Guinea. 
While comparatively few species are confined to the Philip- 
pines and New Guinea, it will be noticed that four genera are 
practically known only from the two regions, two, 7'hayerta 
and Dischidiopsis, confined to the two, Sararanga with the addi- 
tional range to the Solomon Islands, and Koordersiodendron with 
the additional range to Celebes. 
After Celebes, the Australian element in the Philippine flora 
is by far the most marked of that of any other region to the 
south, and considering the great distance that separates that 
continent from the Philippines, this element is all the more 
remarkable. Perhaps the most surprising matter in relation to 
this distribution is the fact that a great number of species, 
and in two cases monotypic genera, are known only from the 
Philippines and Australia, and have not been found as yet in 
any of the intervening islands; it is only reasonable to sup- 
pose that many or most of them will eventually be found 
at intermediate points, when these islands have been more 
thoroughly explored botanically. 
A certain number of Australian types have long been known 
in western Malaya, India, sonthern China and Formosa, but in 
number and interest these wide-spread Australian types do not 
at all compare with the comparatively great development of 
these in the Philippines. India has: //alorhagis, Stylidium, Helicia, 
Cladium, Leptospermum (in the Malay Peninsula and Burma), 
and Schoenus and Leucopogon (in the Malay Peninsula); China 
has all the above except: Leplosperma and Leucopogon, with the 
addition of: Myoporum, Thysanolus and Calogyne, while in Cam- 
bodia one species of Centrolepidaceae is found, and in Cochin- 
china one species of Leplocarpus; Formosa has Xillinga inter-
