THUIA PLICATA, T. ETANDISH1I. 263 



Thuia plicata closely resembles tlie common American species. 

 It is a smaller and more compact tree, more regularly pyramidal 

 in outline, and with shorter branches ; the branchlets are numerous 

 and densely clothed with closely appressed leaves in opposite pairs, 

 of a brownish-green- colour. It is very hardy, and may be planted 

 as an ornamental shrub where many other Conifers of the Cypress 

 tribe would not thrive. 



Habitat. — North-west America, in the neighbourhood of Nootka 

 Sound.* 



Introduced by Archibald Menzies in 1796. 



Thuia plicata dumosa is one of the dwarfest of the Thuias. 

 It is a dense little confused bush, seldom growing more than 2 or 

 3 feet high, with foliage and spray resembling in colour the pre- 

 ceding. 



Thuia plicata variegata differs from the common form in 

 having many of its branchlets with their foliage of a bright golden- 

 yellow. 



Thuia Standishii. — A medium-sized tree, with the habit of the 

 common Arbor Vitse, and resembling also in some respects the 

 Japanese Thuiopsis ; it attains a height of from 40 to 60 feet, 

 according to situation. The branches are horizontal or ascending, 

 irregularly disposed over the trunk, distant, and spreading; the 

 secondaries inclined or sub-pendulous ; the branchlets flat, slender, 

 lycopod-like, and pendulous at their extremities ; and the leaves 

 closely imbricated in four rows, and of a yellowish-green colour. 



Habitat. — The central mountains of Japan. 



Introduced by Mr. Eobert Fortune, in 1861, and named in 

 compliment to the late Mr. John Standish, of Ascot, by whom it 

 was first distributed. 



The Tliuia Standishii of British gardens is derived from a culti- 

 vated form only, which is of smaller siSe and somewhat more dense 

 in habit than the wild tree, which has only recently been met with 

 in the locality named above. By Parlatore, T. Standishii is referred

 sed indigena vix nota et melius in patria investiganda. A T. oecidentali, oui valde affinis
