58 K. Domin. 
a species distinct from V. falcata, while F. von Mueller and J. G. Baker 
(Note on a collection of Ferns from Queensland, Journ. of Bot., XVI [1887], 
p. 163) place it under the typical V. falcata. This remarkable fern seems 
to me to be sufficiently distinguished from V. falcata, although I don't 
think that its characters given by Bailey entitle us to establish it as a 
species. Notwithstanding it is a marked geographical race; the specimens 
gathered by Sayer, Bailey and the author are perfectly identieal, and 
sufficiently different from the type, which is found from the East Indies 
to New Guinea (I saw numerous specimens from Ceylon, Malacca and 
Java) V. falcata Kunze does not occur (as far as at present known) in 
Queensland and therefore is to be taken out of the Australian Flora. 
The specimen, named by Mueller and Baker, and in Bailey's Flora 
1953 is not the typical V. pusilla, but the variety wooroonooran. 
The group of nearly allied species is rather difficult to deal with, as 
the distinctive characteristics vary sometimes to a great degree. The 
East Indian V. sikkimensis differs from the above in its acuminate fronds 
of nearly membranaceous texture. V. debilis seems also to be readily 
distinguished by its central costa prominent as far as the top of the 
frond. V. sulcata, regarded as a distinct species, comes near to V. pusilla 
and could be perhaps placed as a variety of the latter. 
11. Pothos Brownii Domin, nov. spec. 
P. longipedi affinis, sed differt statura robustiori, vaginis planis pro 
more obcuneato-lanceolatis apice plus minusve obcordatis, laminis rigidiori- 
bus majoribusque ovatis usque ovato-lanceolatis, spadicibus robustioribus 
erassioribusque sessilibus vel subsessilibus, baccis majoribus. 
Queensland: Dense vine-scrubs near Harveys Creek and Bellenden 
Ker (Domin 1909—1910). 
This new species is closely allied with P. longipes Schott, but differs 
not only in appearance, but also in its much coarser spikes, which are 
quite or nearly sessile. I found P. Brown represented in the Kew Her- 
barium also from Mt. Dryander (coll. Fitzalan), Port Mackay (Nernst) 
and Rockingham Bay (coll. Dallach y). 
The nearly allied P. cylindricus Presl is distinguished (according to 
the description) by its much smaller fruits. 
Bentham and Bailey (and many others) put all Australian Pothos- 
forms under P. Lowreiri Hook. and Arn., but the latter is quite a distinct 
Chinese species, which has nothing to do with the Australian plant, 
correctly named P. longipes Schott, which is an exceedingly variable 
plant, but always distinct from P. Brownii in its slender and pedunculate 
spikes.
