part near Celebes some floristic affinities are to be noted that 
are not mentioned in the above discussion. The Philippines 
and the Moluccas have in common: Yrichomanes Cumingit C. Chr., 
Plyllocladus protractus Pilg. (also in New Guinea), Mapania 
macrocephala K. Sch. (also in the Bismarck Archipelago), and 
Bikkia grandifiora Reinw. (also in New Guinea); Philippines and 
Amboina: Cyathea integra J. Sm., Vectaria arrigua Copel., Medi- 
milla myrtiformis Triana, and Uncaria setiloba Benth. (also in 
Formosa) ; Philippines and Buru: Pisonia longirostris T. & B.; 
Philippines and Gilolo: Sterculia luzonica Warb.; Philippines and 
Timor: Melia Candollei Sus., Wrightia calycina Dene., Rauwolfia 
amsoniacjolia A. DC. (also in Key), Vitex litloralis Dene, and 
Pimelea sp. nov., closest allied to a species from Timor, the 
two being the only ones of this large genus known north of 
Australia. 
Going farther to the south-east it will be noticed that there 
is a decided floristic relationship between New Guinea and the 
Philippines, but in magnitude not at all approaching that be- 
tween the Philippines and Celebes and other islands south or 
nearly south of the Archipelago, This floristic relationship to 
the south-east extends beyond New Guinea as far as the Society 
Islands in southern Polynesia, and to New Zealand, being deci- 
dedly strongly marked in tropical (that is north-eastern) Australia. 
For the Philippines and New Guinea we have the following 
species: Asy/lenium scandens J. Sm. (also in Fiji), Dennstaedtia 
erythrorachis Diels (also in Celebes), Dryopleris invisa 0. K. (also 
in Polynesia), Vectaria menyanthidis Copel. (also in the Solomon 
Islands), Lugenia Benthamii A. Gray (also Tobie Island), 7/ayeria 
a genus with one or two species in the Philippines and one 
in New Guinea, Péyllocladus protractus Pilg. (also in the Moluc- 
cas), Sararanga, a most striking genus with one species in the 
Philippines and one in New Guinea and the Solomon Islands, 
Rottboellia ophiuroides Benth. (also in Australia), Dianella cae- 
rulea Sims (also in Australia), Alpinia pubifiora K. Sch. (also in 
the Caroline Islands), 4. pulchella K. Sch., Riynchosia calosperma
