Thrinax parviflora, Swartz. 



West India, and also on tlie continent of Central America. 

 The stem of this Fan-Palm attains a height of twenty-five 

 feet. It belongs to the sand-tracts of the coast and may 

 endure our clime. Tlie 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 here. 



Thuya gigantea, ISTuttall. 



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

 The Yellow Cypress of the colonists. A straight, gi-aceful 

 tree 200 feet high, furnishing a valuable building- timber of 

 a pale or light-yellow colour, kno^^ai as the Oregon White 

 Cedar- wood, susceptible of high polish. The diameter of the 

 stem attains ten feet or even more. The timber is light. 

 Canoes carrying four tons have been obtained out of one 

 stem. The bast can be converted into ropes and mats. 



Thuya occidentaliSj Linne. 



North America, particularly frequent in Canada. Northern 

 White Cedar. A fine tree, seventy feet high ; the wood is 

 reddish or yellowish, fine-grained, very tough and resinous, 

 and well fit for building, especially for water-work ; also for 

 turnery and machinery. Michaux mentions that posts of this 

 wood last forty years ; a house built of it was found perfectly 

 sound after sixty years. It prefers moist soil. Valuable for 

 hedge-copses ; it can also be trained into garden-bowers. The 

 shoots and also an essential oil of this tree are used in 

 medicine ; the bast can be converted into ropes. The 

 branches serve for brooms. 



Thuyopsis dolabrata, Siebold and Zuccarini. 



Japan. A majestic tree, furnishing an excellent hard timber 

 of a red colour. 



Thymelaea tinctoria, Endlicher. {Passerina tinctoria, Pourr.) 



Portugal, Spain, South France. A small shrub. It yields a 

 yellow dye. Cursorily it may be noted here, that some of 

 our Pimelese contain a blue pigment, which has not yet been 

 fully tested. Their bark produces more or less of Daphnin 

 and of the volatile acrid prmciple, for which the bark of 

 Daphne Mezereum (L.) is used. These are remarkably 

 developed in the Victorian Pimelea stricta (Meissn). The 

 bark of many is also pervaded by a tough fibre, that of the 

 tall Pimelea clavata (Labill.), a West Australian bush, being 

 particularly tenacious, and used for whips.
