‘here to draw attention to the likelihood of its improv- 
ing in culture, and to its fitness of being grown on 
arid land. 
Atriplex nummularium, Lindley. — From Queens- 
land through the desert-tracts to Victoria and South 
Australia. One of the tallest and most fattening and 
wholesome of our pastoral salt-bushes, and although 
a native plant, even here highly recommendable for 
artificial rearing, as the spontaneously-growing plants, 
by close occupation of the sheep and cattle runs, have 
largely disappeared, and as this useful bush, even here, 
in many wide tracts does not exist. 
Atriplex spongiosum, F. v. Mueller. — Through a 
great partof Central Australia, extending to the west 
coast. Available like the preceding, and like A. hali- 
moides, A. holocarpum and several other species, for 
salt-bush culture. 
Avenaelatior, Linné.—Europe, Middle Asia, North 
Africa. This tall grass should not be passed altogether 
on this occasion, although it becomes easily irrepres- 
sible on account of its wide-creeping roots. It should 
here be chosen for dry and barren tracts of country, 
it having proved to resist our occasional droughts 
even better than rye-grass. The bulk yielded by it 
is great, it submits well todepasturing, and gives two 
or three crops of hay annually; it is, however, not 
so much relished by animals as many other grasses. 
Averrhoa Carambola, Linné.—Insular India. Dr. 
Hooker having found this small tree on the Upper 
Indus as far as Lahore, it may reasonably be antici- 
pated that success would attend its rearing in the 
warmest and moistest parts of our colonial territory. 
The fruit occurs in a sweet and acid variety ; the for-
