Tropaeolum sessilifolium, Poeppig. 



Chili. Among the species of this genus one of the most 

 eligible for its tubers, which can be consumed even in a raw 

 state and are larger than those of most other Tropseolums, while 

 the stems are short and procumbent (Philippi). 



Tropaeolum tuberosum, Ruiz and Pavon. 



Peru. The tuberous root serves as an esculent. 



Trophis Americana, Linne. 



West Indian Archipelagus. The foliage of this milky tree 

 has been recommended as food for the silk-insect. In Cuba 

 and Jamaica it is used as provender for cattle and sheep. 



Tuber aestivum, Yittadini. 



The Truffle most in the markets of England. The white 

 British Truffle, Chairomyces meandriformis (Yitt.), though 

 large is valued less. In the Department Yaucluse (Prance) 

 alone about 60,000 lbs. of Truffles are collected annually at 

 a value of about £4000. Many other kinds of Truffles are 

 in use. Our own native Truffle, Mylitta Australis (Berk.) 

 attains sometimes the size of the Cocos-nut, and is also a fair 

 esculent. It seems also quite feasible to naturalise the best 

 of edible fungi of other genera, although such may not be 

 amenable to regular culture. 



Tuber albidum, Fries. 



Occurs with T. sestivum, but is smaller and less agreeable in 

 taste. The means of 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 cibarium, Sibthorp. 



Middle and South Europe. The Black Truffle. Like all 

 others growing under ground, and generally found in forest- 

 soil of limestone formations. It attains a weight over one 

 pound. Experiments for naturalisation may be effected with 

 every prospect of success by conveying the Truffle in its. 

 native soil to us, and locating it in calcareous places of our 

 forest-regions. As condiment or merely in a roasted state it 

 aJffords an aromatic food. T. melanosporum (Yitt.) from 

 France, Germany and Italy, is of a still more exquisite taste 

 than T. cibarium, indeed of strawberry flavour. 



Tuber magnatum, Pico. 



Grey Truffle. South Europe. One of the most esteemed 

 Truffles, with some garlic flavour. 



Tuber rufum, Pico. 



Bed Truffle, especially in vineyards. Much used for food^ 

 but smaller than the Terfezia Truffles.
