EUCALYPTUS TREES. 517 
Thouarea sarmentosa, Persoon.—Tropical shores of 
the eastern hemisphere. This curious and tender 
grass might be easily introduced, to help bind the 
sand on sea-beaches, 
Tilia argentea, Desfontaines.*—The Silver Lime-tree 
of South-east Europe. The wood is not attacked by 
boring insects. The flowers are deliciously fragrant, 
and yield, on distillation, a precious oil. 
Tinguarra Sicula, Parlatore.—In the countries at 
the Mediterranean Sea. The root is edible and celery- 
like. 
Tristania conferta, R. Brown. — New South Wales 
and Queensland. <A noble, shady tree, attaining a 
height of 150 feet. It is not only eligible as an ave- 
nue tree, but also as producing select, lasting timber; 
ribs of vessels from this tree have lasted unimpaired 
80 years and more. : 
Triticum junceum, Linné.—Europe and North-Af- 
rica. A rigid grass with pungent-leaves and exten- 
sively creeping roots, requiring sea-sand for its per- 
manent growth. One of the best of grasses to keep 
rolling sand-ridges together, and particularly eligible 
where cattle and other domestic animals cannot read- 
ily be prevented from getting access. 
Triphasia Aurantiola, Loureiro. — South-east Asia. 
‘This shrub is worth cultivation for the exquisite fra- 
grance of its flowers. The fruits, though small, are of 
pleasant sweetness. The plant may prove also adapt- 
ed for hedges. Glycosmis citrifolia, Lindley, and 
Claussena punctata, Oliver, also both East Asiatic 
fruit-shrubs, may possibly show themselves hardy in 
our sheltered forest-regions. 
Tropzeolum tuberosum, Ruiz and Pavon. — Peru, 
The tuberous root serves as an esculent,
