many as 500 large seeds. The latter iu a boiled state are edible, or 

 a large quantity of oil, fit for the table, can be pressed from them. 

 The root is fleshy. A second huge species of similar use, T. occi- 

 dentalis (J. Hooker), occurs in Guinea. The genus-name Joliffia is 

 coetaneous, if not anterior. These superb plants may not be abso- 

 lutely restricted to hot tropical lowlands, and therefore possibly 

 endure a warm temperate clime. 



Terfezia leonis, Tulasne. (Cheiromyces leonis, Tul.) 



Southern Europe, Northern Africa. This edible truffle, together 

 with other species of this and other genera, is deserving of wide 

 naturalization. 



Terminalia Buceras, J. Hooker. (Bucida Buceras, Linn.) 



From the Antilles to Brazil. One of the Mangrove-trees, living in 

 salt-water. Possibly hardy and calculated to consolidate mud-shores. 

 The Tussa-silkworm inhabits, among other trees, several Terminalias. 



Terminalia Catappa, Linne". 



India, continental as well as insular, ascending only lower moun- 

 tain-regions, also North-Eastern Australia. Few trees, as stated by 

 Roxburgh, surpass this in elegance and beauty. We have yet to 

 learn, whether it can be naturalized in temperate climes, which it 

 especially deserves for its nuts. The seeds are almond-like, of fil- 

 bert taste, and wholesome. The astringent fruits" of several other 

 species constitute an article of trade, sought for a lasting black dye. 

 T. parviflora (Thwaites) forms a large tree in Ceylon, at elevations 

 up to 4,000 feet. Several of their congeners reach extra-tropic 

 latitudes in Eastern Australia. 



Terminalia Chebula, Retzius. 



On the- drier mountains of India, ascending to 5,000 feet. A tree 

 rising to about 100 feet. The seeds are of hazel taste; the galls of 

 the leaves and also the young fruits, the latter known as Myrobalans, 

 serve for superior dye and tanning material. Some of its congeners 

 answer the same purpose, among them T. Belerica (Roxburgh). 



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. It produces its suc- 

 culent branchlets and leaves also in the hottest weather and driest 

 . localities (Rhind). Rapid in growth. The seeds will keep fully five 

 years (Vilmorin). 



Tetragonia implexicoma, J. Hooker. 



Extra-tropical Australia, New Zealand, Chatham-Island. A 

 frutescent, widely expanding plant, forming often large natural 

 festoons, or trailing and climbing over rocks and sand, never far
