humerable South African Heaths, Stapeliz, the Me- 
sembryanthema, Pelargonia, lily-like plants, and many 
others, once the pride of European conservatories, 
can, with increased sea traffic, now gradually be in- 
troduced as beautifnl objects of trade into this coun- 
try, where they need no glass protection. It leads 
too far to speak of the still more readily accessible 
numerous showy plants of South-west Australia, but 
among which, as a mere instance, the gorgeous Ani- 
gozanthi, the lovely Stylidia, the gay Banksiz, and 
the fragrant Boronias may be mentioned. 
Before leaving this topic, I may remind you that 
many esculent plants of foreign countries are desery- 
ing yet of test culture, and, perhaps, general adop- 
tion in this country. The Dolichos sesquipedalis, of 
South American, is a bean, cultivated in France on 
account of its tender pod. The Arracha esculenta, an 
umbellate from the cooler mountains of Central Ameri- 
ca, yields there, for universal use, its edible root. 
The climbing Chocho, of West India (Sechium edule), 
proved hardy in Madeira, and furnishes a root and 
fruit both palatable and wholesome. Vigna subter- 
ranea is the Earth Nut of Natal. The Taro of Tahiti 
(Calocasi macrorrhiza), though perfectly enduring our 
lowland clime, is, as yet, with allied species, but lit- 
tle cultivated — neither the Soja of Japan (Glycine 
Soja), nor the Caper of the Mediterranean. The Sea- 
kales (Crambe Maritima and C. Tatarica) might be 
naturalized on our sandy shores. 
Regarding fibres, much yet requires to be effected 
by capitalists and cultivators, to turn such plants as 
the Grasscloth shrub, which I distributed for upward 
of a dozen years, to commercial importance for facto-
