of pleasant sweetness. The plant mayj>rove also adapted 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. 
Tropaeolum tuberosum, Ruiz and Pavon. 
Peru. The tuberous root serves as an esculent. 
Tuber albidum, Fries. 
Occurs with T. cestivum, but is smaller and less agreeable in 
taste. The means for transferring truffles and any other edible 
fungi from one country to another, require yet to be further 
studied and finally devised, but they appear quite feasible. 
Tuber magnatum, Pico. 
Grey Truffle. South Europe. One of the most esteemed truffles, 
with some garlic flavour. 
Tuber rufum, Pico. 
Red Truffle, especially in vineyards. Much used for food, but 
smaller than the Terfezia truffles. 
Ulmus erassifolia, Nuttall, 
The evergreen Elm of Mexico and Texas. 
Ulmus montana, W ithering. 
The Wych Elm. Europe and extratropical Asia. Attains a 
height of 120 feet. 
Ulmus Mexieana, Planchon. 
Cordillieres of North America. This elm attains a height of 
60 feet or perhaps more. 
Ulmus pedunoulata, Fougeraux. {U. ciliata, Ehrhart.) 
Europe and Asia, through their middle zone. A fine avenue 
tree. 
Ulmus parvifolia, Jacquin 
The evergreen elm of China, Japan and Queensland. A similar 
tree is found in the Himalayan Mountains. 
Vigna lanceolata, Bentham. 
Tropical and subtropical Australia. Mr. O’Shanesy observes that 
this twiner produces, along with the ordinary cylindrical pods, 
others underground from buried flowers, and these somewhat 
resemble the fruit of Arachis. The plant is available for culinary 
purposes.
