part of New South Wales, while some, including 
Araucaria Bidwelli, or the Bunya-Bunya-tree, so re- 
markable for its large, edible, nutlike seeds, and the 
Australian Kauri, Dammara robusta, are confined to 
very circumscribed or solitary areas. The absence of 
superior spice-plants (as far as hitherto ascertained) 
amidst a vegetation of prevailing Indian type is not 
a little remarkable, for Cinnamomum Laubatii ranks 
only as a noble timber-tree, and the native nutmegs 
are inert. The scantiness of acanthaceous plants is 
also a noticgable fact. Podostemonee have not yet 
been found. Many plants of great interest to the 
phytographer are seemingly never quitting the north- 
eastern peninsula ; among these the Banksian ba- 
nana (Musa Banksii), the pitcher-plant (Nepenthes 
Kennedyana), the vermillion - flowered Eugenia Wil- 
sonii, the curious Helmholtzia acorifolia, the Mar 
shal-tree, Archidendron Vaillantii (the only plant of 
the vast order of Leguminose with numerous styles), 
the splendid Diplanthera quadrifolia, Ficus magnifo- 
lia, with leaves two feet long, the tall Cardwellia sub- 
limis, and the splendid Cryptocarpa Mackinnoniana, 
are especially remarkable. Rhapidophara, Pothos, 
Piper, together with a host of Lianes, especially gay 
through the prevalence of Ipomeas, tend with so many 
other plants to impart to the jungle part of Australia 
all the luxuriance of tropical vegetation. Of the two 
great Nettle-trees, the Laportea gigas occurs in the most 
northern regions, while Laportea photinifolia is more 
widely diffused. Helicia is represented by a number 
of fine trees far south, some bearing edible nuts. 
Doryanthes excelsa, the tall spear-lily, is confined to 
the forests of New South Wales. The flowers of Ob-
