528 Select Plants for Industrial Culture and 



Thapsia edulis, Bentham. (Monizia edulis, Lowe.) ,. 



On the Island of Deserte Grande, near Madeira, where it is called 

 the Carrot-tree. It might be of some use, to bring this almost 

 shrubby umbellate to the cliffs of other shores ; though the root is 

 inferior to a carrot, perhaps cultivation would improve it. T. 

 decipiens, Bentham (Melanoselinum decipiens, Lowe), from Madeira, 

 is of palm-like, habit and desirable for scenic effects in plant-grouping. 

 T. Silphium (Viviani) is the Silphiou of the ancients. 



Theligonum Cynocrambe, Linn6. 



Countries around the Mediterranean Sea, extending to the Canary- 

 Islands. An annual spinach-plant of somewhat aperient effect. 



Thouarea sarmentosa, Persoon. 



Tropical shores of the eastern hemisphere. This curious and 

 tender grass might be easily introduced, to help in binding the sand 

 on sea-beaches. It likes wet ground. 



Thrinax parviflora, Swartz. 



South-Florida, West-Indies, also on the continent of Central 

 America. The stem of this Fan-Palm attains a height, according 

 to Dr. Chapman, of about 40 feet, but is extremely slender. Belongs 

 to the sand-tracts of the coast ; hardy in the South of France to 

 43 32' N. lat. [Naudin]. The fibre of this palm forms material 

 for ropes. T. argentea (Loddiges) is an allied palm. The few other 

 species of the genus from the West-Indies also deserve trial-culture. 



Thuya dolabrata, Linn6 fil. (Thuyopsis dofo&rato, Siebold and Zuccarini.) 

 The "Akeki" of Japan, ascending to an elevation of 8,000 feet. 

 A majestic tree of conical shape and drooping habit, growing to 

 100 feet high, attaining a stem-diameter of 3 feet. It delights in 

 sheltered and rather moist situations, and is used in China and 

 Japan for avenues. Hardy in Norway to lat. 58 27' [Schuebeler]. 

 Bore exceptionally severe winter-cold in Germany [H. .Koehler]. 

 It furnishes an excellent hard durable timber of a reddish colour, 

 employed particularly for water-works, ship-, bridge-, and house- 

 building ; the bast-fibre is strong and durable, thus made into ropes 

 [Prof. Luerssen]. 



Thuya gig-antea, Nuttall. 



North-Western America. The yellow Cypress of the Colonists, 

 also known as Oregon Bed or White Cedar. A straight tree, in 

 some instances known to have attained a height of 325 feet, with a 

 stem 22 feet in diameter ; it furnishes a valuable building timber of a 

 pale or light-yellow colour, susceptible of high polish and remarkably 

 fragrant, thus serving even for incense [T. Meehan]. It is light, 

 soft, smooth and durable, and makes the finest sashes, doors,
