1388 FOREST CULTURE AND 
eronia palmicola are more minute than those of any 
other orchideous plant, although more than two thou- 
sand species are known from various parts of the globe. 
The display of trees eligible for avenues from these 
jungles is large. The tall Fern-palm (Zamia Deniso- 
nii), one of the most stately members of the varied 
Australian vegetation, is widely, but nowhere copi- 
ously, diffused along the east coast ; it yields a kind 
of sago, like allied plants. The beans of Castanosper- 
mum Australe, which are rich in starch, and those of 
Entada pursetha, from a pod often four feet long, are, 
with very many other vegetable substances, on which 
Mons. Thozet has shed much light, converted by the 
aborigines into food. 
If plants representing the genera Berberis, Impa- 
tiens, Rosa, Begonia, Ilex, Rhododendron, Vaccini- 
um, or, perhaps, even Firs, Cypresses, and Oaks, do 
at all occur in Australia, as in the middle regions of 
the mountains of India, it will be on the highest hills 
of north-east Australia—namely, on the Bellenden’ 
Ker ranges, mountains still unapproachable through 
the hostility of the natives—where they will find the 
cooler and simultaneously moist tropical climate con- 
genial to their existence. But whatever may be the 
variety and wealth of the primitive flora of East Aus- 
tralia, it is only by the active intelligence and exer- 
tions of man that the greatest riches can be wrought 
from the soil. Whatever plants he may choose to 
raise—whatever costly spices, luscious fruits, expen- 
sive dyes; whether cacao, manihot, or other aliment- 
ary plants; whether sugar, coffee, or any others of 
more extensive tropical tillage—for all may be found 
wide tracts fitted for their new home.
