sixty-one species of which one extends from Australia to India 
and Japan, one is found in the Philippines, China and India, 
the remainder being entirely confined to Australia, Tasmania 
and New Zealand, Didiscus saniculaefolius Merr. (also in Borneo), 
not found in Australia, but a representative of a large and 
typical Australian genus, and the only representative known 
north of Australia, Leucopogon suaveolens Hook. f. (also in Borneo), 
not found in Australia but a representative of a very large 
and typical Australian genus, /schnostemma carnosum Merr. & 
Rolfe (also in the Malay Peninsula) a monotypic genus, /po- 
moea congesta R. Br. (also in Polynesia) Stylidium alsinoides R. 
Br., the genus comprising 103 species, two confined to Asia, 
one to Asia and Australia, one Philippines and Australia, the 
remainder Australian, Galium Gaudichaudii DC., Calogyne pilosa 
R. Br., the genus entirely Australian except C. chinensis Benth., 
of southern China, and Centratherum fruticosum Vid., very clo- 
sely allied to an Australian species. 
Going farther to the south-east it is somewhat surprising to- 
find some peculiar affinities between the floras of the Philippines 
and New Zealand, and also with southern Polynesia. Wallace 
in his “Island Life’, in the chapter on the flora of New Zea- 
land, explains the probable origin of the New Zealand flora 
through the apparent previous connection of that group with 
what later formed the eastern part of the Australian continent, 
but that this connection took place at a time when this 
“astern Australian” island was separated from western Aus- 
tralia. In its turn north-eastern or tropical Australia received 
its present flora largely from Malaya, and the apparent pre- 
vious connection between New Zealand and Australia was with 
the tropical and subtropical portion, not with the temperate 
part, which explains not only the presence of a considerable 
number of tropical Malayan types in the New Zealand flora, 
but also a means by which species now common to the Phi- 
lippines and New Zealand may have been distributed. The 
striking cases of floristic affinity between the Philippines and
