 glauca. 



L. DoNiANA, Endlicher. (Synonym : Thuya 

 Doniana, Hooker,) New Zealand. 1848. — Though 

 usually described as tender, there are, in certain 

 parts of the country, well -furnished and beauti- 

 ful specimens of this tree to be seen. In the 

 north of Ireland it forms a handsome specimen, 

 with foliage of the richest description ; while 

 in southern and especially western England, 

 I have seen well -grown plants. It presents a 

 perfect pyramid of flattened, fern-hke branchlets, 

 thickly covered with beautiful foliage of a deep, 

 unchanging green, and with little or no silvery 

 markings on the under sides.. It is readily dis- 

 tinguished from L, chilensis by the more closely 

 arranged leaves and by the absence of the silvery 

 line on the under sides of these, as also by its 

 richer and brighter green colour. 



L. TETRAGONA, EiidlicJier. (Synonym : Thuya 

 tetragona. Hooker.) Patagonia and Chile. 1849. — 

 By the Chilians this is justly valued as one of the 

 most important trees of their country, the timber 

 being of great value for constructive purposes. In 

 this country, unless in very favourable situations, 

 it does not succeed well, and many specimens have 

 died out prematurely. Where it does thrive it is 

 certainly a distinct and beautiful tree, of somewhat 

 broadly pyramidal habit of growth, the branches 

 being stiff, stout, and horizontally arranged, with 

 the tips upturned. The leaves are bright green, 

 broadly decurrent at the base, and about a quarter 

 of an inch long. Cones smaller than those of any 

 other species. I have seen this interesting conifer
