374 Select Plants for Industrial Culture 



away from the coast. As a spinach-plant it is of not less value than 

 the preceding species. It is well adapted for the formation of bowers 

 even in arid places; it also helps to bind sand. T. trigyna (Banks 

 and Solander) seems identical. 



Teucrium Marum, Linn. 



Countries on the Mediterranean Sea. A small somewhat shrubby 

 plant, in use for the sake of its scent, containing a peculiar stearopten. 

 T. Scordium, from Europe and Middle Asia, T. Chamaedrys, T. 

 Folium and T. Creticum, L., from South-Europe, are occasionally 

 drawn into medical use. All these, together with many other species 

 from various countries, are pleasantly odorous. 



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 Silphion 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. 



Thrinax parviflora, Swartz. 



South-Florida, West-Indies and 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; Linne fil. (Thuyopsis dolabrata, 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 50 feet 

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

 rather moist situations, and is used in China and Japan for avenues. 

 Hardy in Norway to lat. 58 27' (Schuebeler). It furnishes an 

 excellent hard timber of a red color. 



Thuya gigantea, Nuttall. 



North- Western America. The Yellow Cypress of the colonists, 

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