326 SELECT PLANTS FOR INDUSTRIAL CULTURE 



of candles. The yield is comparatively large. Trial cultures 

 with this tree might be instituted in humid forest valleys. 

 T. laurifolia (Jacq.), of tropical Asia and Australia, and T. 

 japonica (Sprengel), are noted as similarly utilitarian. 



Teuerium Marum, Linne. 



Countries on the Mediterranean Sea. A small somewhat 

 shrubby plant, in use for the sake of its scent, containing a 

 peculiar stearopten. T. Scordium (L.) from Europe and 

 Middle Asia, T. Chamaedrys (L.), T. Folium (L.), 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 our shores ; though 

 the root is inferior to a carrot, perhaps cultivation would 

 improve it. T. decipiens, Benth. (Melanoselinum decipiens, 

 Lowe), from Madeira, is of palm-like habit and desirable for 

 scenic effects in plant-grouping. 



Theligonum cynocrambe, Linne. 



Countries around the Mediterranean Sea. 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 binding the 



sand on sea-beaches. 







Thrinax parviflora, Swartz. 



South Florida, West India, and also on the continent of Central 

 America. The stem of this Fan Palm attains a height of 25 

 feet, or according to Chapman 40 feet, but extremely slender. 

 It belongs to the sand tracts of the coast and may endure a 

 temperate clime. The fibre of this Palm forms material for 

 ropes. T. argentea (Lodd.) is a closely allied Palm. The few 

 other species of the genus deserve also trial culture. 



Thuya gigantea, Nuttall. 



North-West America, on the banks of the Columbia River. 

 The Yellow Cypress of the colonists, also known as Oregon 

 Red Cedar. A straight graceful tree 200 feet high, in some
