The variety Corneyana, whose native country is uncertain, has branches 

 and branchlets pendulous. The umbos of the scales are less or not at all 

 developed. 



It also does well in the Sydney district. It is not so " stiff" looking as the 

 type form.

4. Thuia (including Thujopsis) often spelt Thuja. 



"TheThuias, with one exception, T. yigantea, are medium-sized or low ever- 

 green trees of narrowly conical outline ; or dense globose, fastigiate, or dwarf 

 shrubs that have deviated under cultivation from the ordinary habit of the 

 species. As here understood, the genus includes five species inhabiting a belt 

 in the north temperate zone, extending with interruptions through North 

 America and Asia, between the 30th and 50th parallels of north latitude. "-

(1.) T. dolobrata, L.f. The " Akeki " of Japan. 



A tree or undershrub used as an avenue tree in China and Japan. The 

 wood is very durable, and is used for many purposes ; the bast is made into 

 ropes. 



It is scarcely suitable for a dry climate, as it is liable to die suddenly 

 during a spell of warm, dry weather. 



L 2 a (Sydney Botanic Gardens). 



(2.) T. yigantea, Nuttall. "Western Arbor Vitre ; the Red or Canoe 

 Cedar of Oregon." 



The tallest of all the Thuias, attaining a height in its native country 

 (British Columbia, northern California, &c.) of 200 feet. It flourishes best 

 in rii-h river valleys. 



It is a very handsome species, and it yields a valuable fissile timber. It 

 certainly ought to be added to the number of the Conifers to be planted as 

 extensively as convenient in the colder parts of New South Wales. 



We have had it in the Sydney Botanic Gardens from time to time, but it 

 does not last in the Sydney climate. 



(3.) T. occidentalis, L. "Arbor Vte." Called White Cedar in the 

 United States and Canada. 



It is a tree of medium size, very common in swamp land in Canada and the 

 north-eastern United St-ttes. Like other Conifers, it varies much in size 

 according to soil and climate. 



It is, probably, the first American Conifer introduced into Great Britain 

 and is a most useful plant, although it has had to submit to the competition 

 of many Conifers from different parts of the world. 



Its leaves have been used as a remedy for rheumatism on account of their 

 sudorific properties. Its wood is used for posts and similar purposes, on 

 account of its durability. It forms a fine hedge.
