Cape Cleveland, north-westward to Arnhem’s Land. 
NYCTAGINEiE. 
PISONIA ACULEATA. 
Z. Sp. 1511. 
Sinclair Island. 
A robust climbing plant, according to Mr. Fitzalan. The collection contains only 
fruit-bearing branches, which agree in every respect with the plant represented under fig. 1764 
in Wight’s icones. Lamark’s illustration 861 exhibits narrower more pointed leaves and shorter 
pedicels. 
Dr. Hooker includes this species as a dubious one in his list of Indian phanerogamic 
plants to be found likewise in Australia. Ilis enumeration, as predicted by that learned botanist 
himself, will in future probably be largely augmented, and may on this occasion be supplemented 
by the following Asiatic plants : — Cardamias parviflora Z., Lepidium ruderale Z., Barbarea 
vulgaris B. Br ., Abroma fastuosa R. Br ., Geranium dissectum Z., Ryssopterys tiligefoiia Bl.,

This list includes some species as yet in Australia not found within the tropics. Several 
plants from the Pacific Islands, including Loranthus insuiarum A. Gr., Lepturus repens Br., 
found also in Australia, will probably be yet detected in the Indian dominions. 
CYCADEiE. 
CYCAS MEDIA. 
R. Br. Prodr. 848. 
Cape Upstart. 
This plant attains, according to Mr. Fitzalan’s notes, a height of 70 feet. In those parts 
of tropical East Australia, where it was noticed by myself, it occurred of only inconsiderable 
height. 
CONIFERS. 
ARAUCARIA CUNN1NGHAMI. 
Alton, in Lamb. Pin. iii. t. 96 ; Fndl. Synops. Conifer . 187. 
Cumberland Islands. Occurs southward to the vicinity of the Hastings River. 
The branches with immature fruit gathered during the Burdekin expedition accord fully 
with others from Moreton Bay, Rockhampton and the Hastings River. It remains as yet. 
unascertained whether more than one Araucaria belongs to the East Australian flora. Mr. 
Fitzalan offers on this pine the following notes : — “ Yery abundant from Percy’s Islands 
upwards. On Percy Islands it differs but little from the Moreton Bay pine, except in the 
invariable regularity of its branches, these being in regular tiers opposite ; the Moreton Bay 
pine is seldom so ; as we go further north this regularity increases and the foliage becomes more 
glaucous, until at Port Molle and on Whitsunday Island the tree assumes the habit of the New 
Caledonian species, the tree being conical, the tiers of branches perfectly regular and having a 
slight droop at their tips. We cut a spar of it on Magnetical Island to make a topmast, and the 
wood was hard and close-grained, paler than that of the Moreton Bay pine, and would not swim. 
It produces a white resin abundantly.” 
A new species of the magnificent genus Araucaria has very lately been discovered by 
Mr. Will. Duncan, botanical collector to John Rule, Esq., of Melbourne, having been found 
covering the summit of a lofty volcano on an island near New Caledonia. It may be designated, 
in honor of the gentleman through whose arrangements the discovery was accomplished,
