IN EXTRA-TROPICAL COUNTRIES. 331 



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



From the Antilles to Brazil. One of the Mangrove trees, thus 

 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, ascending mountain regions. Few trees, as stated by Rox- 

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

 whether it can be naturalised in temperate climes, which it especially 

 deserves for its nuts. Several species extend in East Australia to 

 sub-tropical latitudes. The seeds are almond-like, of filbert taste, 

 and wholesome. The astringent fruits of several other species 

 form an article of trade, sought for a lasting black dye. T. parvi- 

 flora (Thwaites) forms a large tree in Ceylon, at elevations up to 

 4,000 feet. 



Terminalia Chebula, Retzius. 



On the drier mountains of India. The seeds of this tree are of 

 hazel taste ; the galls of the leaves and also the young fruits, known 

 as Myrobalams, serve for superior dye and tanning material. Some 

 other congeners serve the same purpose. 



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 Yaldivia. An annual herb, 

 useful as a culinary vegetable, also for binding drift-sand. 



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 away 

 from the coast. As a Spinach plant it is as valuable as the preceding 

 species. It is well adapted for the formation of bowers in arid 

 places ; it helps also to bind sand. T. trigyna (Banks and Solander) 

 seems identical. 



Tetranthera Californica, Hooker and Arnott.* (Oreodaplme Cali- 

 fornica, Nees.) 



Oregon and California, where it is called the Mountain Laurel or 

 Bay Tree. On the banks of rivers attaining a height of 100 feet, 

 throughout pervaded by a somewhat camphoric odour. Wood hard, 

 close-grained, durable, susceptible of a high polish, easily worked, 

 used for superior flooring, turnery, and manifold other select work. 

 The tree is easily cultivated, but not of quick growth. (Dr. Behr 

 and Prof. Bolander.)
