media R. Br., and Acacia Richei A. Gray; Western Malaya has 
all the typically Australian genera that extend to India and 
the Malay Peninsula and in addition Didiscus, Patersonia and 
Drapetes, the latter three in north-eastern Borneo. Eastern 
Malaya has other Australian types that do not extend farther 
north and west, but so far as botanical exploration shows at 
the present time, no other part of Malaya, except New Guinea, 
shows so many Australian types as do the Philippines. All 
the above genera with the exception of Myoporum, sai a: 
and Drapefes are found in the Philippines. 
There are found in the Philippines representatives of six typi- 
cally Australian families: Proteaceae. Halorhagidaceae, Epacrida- 
ceae, Styhdiaceae, Cintrolemdaceae, and Stackhousiaceae, the last 
two being almost unique in their Philippine representatives as 
extending the range of the families north of Australia, but 
species of the first four are found all over Malaya to southern 
China and India. In addition to the above characteristic Austra- 
lian families, we have also representatives of the following 15 
characteristic Australian genera in other families. MMicro/aena, 
Cladium, Schoenus, Thysanotus, Patersonia, Phrygilanthus, Psoralea, 
Chanthus, Pleiogynium, Pimelea, Eucalyptus, Leptospermum, Osbor- 
mia, Didiscus, and Calogyne, many of which are not known from 
any other part of Malaya, and several, such as: Microlaena, 
Phrygilanthus, Pleiogynium, and Osbornia have no known repre- 
sentatives north of Australia, other than those found in the 
Philippines. 
Taking up the Australian element in detail it is found that 
the following list of species, unless otherwise stated, are found 
only in Australia and the Philippines: Axdropogon Baileyi ¥. 
Muell., A. filivendulus var. lachnatherus Hack., 4. fragilis R. Br., 
Aristida stipoides RK. Br. (represented in the Philippines by @ 
variety), JMicrolaena stipoides R. Br., the genus with five spe- 
cies in Australia and New Zealand, the present one being the 
sole representative that extends north of Australia, Perolis rara 
R. Br., Pollinia irritans Hack., Rottboellia ophiuroides Benth. (also 
in New Guinea), Carea fuirenoides Gaudich. (also in the Marianne
