length of 100 feet, with fringed lilac flowers of extra- 
ordinary beauty and with fruits attaining a weight of 
60 lbs., and containing at times as many as 500 large 
seeds. The latter, in a boiled state, are eatable, or a 
large quantity of oil can be pressed from them. The 
root is fleshy. Our Summers in the Murray: country 
are likely to bring this plant regularly into bearing. 
A second huge species of similar use, T. occidentalis, 
J. Hook., occurs in Guinea. 
Terfezia Leonis, Tulasne. — South Europe, North 
America. This edible truffle, together with other 
species of this and other genera, is deserving of nat- 
uralization in Australia. 
Tetragonia implexicoma, J. Hook. — Extra-tropic 
Australia, New Zealand, Chatham’s Island. A fru- 
tescent, widely-expanding plant, forming often large 
natural festoons, or trailing and climbing over rocks 
and sand, never away from the coast. As a spinach- 
plant it is as valuable as the succeeding species. It 
is well-adapted for the formation of bowers in arid 
places. TT. trigyna, Banks and Soland., seems identi- 
cal. 
Tetragonia expansa, Murray.—The New Zealand 
Spinach, occurring also on many places of the coast 
and in the desert-interior of Australia. Known also 
from New Caledonia, China, Japan, and Valdivia. 
An annual herb, useful as a culinary vegetable, also 
for binding drift-sand. 
Teucrium Marum, L.—Countries at the Mediterra- 
nean Sea. A small, somewhat shrubby plant, in use 
' for the sake of its scent, containing a peculiar stearop- 
ten. T. Scordium, L., from Europe and Middle Asia, 
T. Chameedrys, L., T. Polium, L., and T. Creticum,
