wliieh are not less beautiful, are not suiEciently robust to bear our 

 climate out of doors. From the peculiarly rigid and apparently artificial 

 habit of A. imbricata, and its singular dark green fohage, it has always, 

 since its introduction, been a special favomnte. Intrinsically a fine 

 object, it is extremely effective in ornamental scenery in the way of 

 contrast to the more massive and less marked forms of other trees and 

 shrubs. At the same time it must be admitted that it does not group 

 very well by itself. 



SuBOEDEE III. CUNNINGRAMIUJE. 

 Gen. 1. CUNNINaHAMIA. 



1. C. Smensis, s h, 40-50 ft. 



Gen. 2. SEQUOIA. 

 1. S. gigantea, 200 ft. 2. S. sempervirens. 



CunningTiamia Sinends is not a very ornamental tree when young, 

 but it improves in this respect as it increases in age. It is probably, 

 however, always inferior to the Araucaria. Sequoia gigantea is a re- 

 markable evergreen tree from Cahfomia, of rapid growth, and requiring 

 shelter and a somewhat moist climate. In exposed situations its fine 

 foliage is liable to be injured by winds. The branches alternate round 

 the tnmk, and as they are short they give the tree an upright form. 

 We suspect that at present there is some confasion, or at least indis- 

 tinctness of view, among botanists regarding the two species. 



Order III. PODOCAEPE^. 



Gen. 1. PODOCAEPUS. 

 1. P. nubigena, h ? Patagonia. 



aen. 2. MICROCACHEYS. 



1. M. tetragona, 15-20 ft. Van Diemen's Zand. 



Oen. 3. SAXE-GOTHEA. 

 1. S. conspicua, 30 ft. Patagonia. 

 Of this fine Natural Order there are, unfortunately, of the species 

 introduced into this coimtry, very few hardy. We have given the above 

 in the hope that, as two have proved sufficiently robust to stand our 

 climate, the others will do so also. Saxe- Oothea, or Prince Albert's Yew, 

 has scarcely been definitively located, as yet, in the Natural System ; 

 but we have ventured to place it in this Order. It promises to be a 

 valuable addition to our ornamental trees.
