264 THE BOOK OF EVERGREENS. 



Smaller tlian the preceding, not exceeding 70 or 100 feet 

 in height, but strikingly beautiful in all its parts. It is 

 from the section of country north of Rio Janeiro, and was 

 introduced into England in 1819. It is more tender than 

 A. irribricata, but a much more rapid grower than that 

 species. The large, sessile cones are about 6 inches in di- 

 ameter, with the scales ending in sharp spines. The seeds 

 are produced singly and are about 2 inches long. 



Var, Ridolfiana, SavL This form is more robust in 

 growth, with larger and longer leaves, and probably more 

 hardy than the species. 



Var, graciliS; Carriere. This variety is the exact re- 

 verse of the above, and has bright green leaves when 

 young, and in its general appearance closely resembles the 

 Cunninghamia Sinensis. Branches undivided and droop- 

 ing at the extremities. 



4. A. Cookii, Brown. Is from the islands of Aniteura, 

 New Hebrides, and New Caledonia. It grows to the 

 height of from 150 to 200 feet. The branches are placed 

 in very regular whorls, horizontal in growth, and very 

 densely clothed with leaves. Cones smaller than either 

 of the preceding. 



5. A. Cumiinghamii, Alton. MORETON BAY PIKE. 

 From Moreton Bay and elsewhere in Australia, where it 

 constitutes whole forests, frequently growing to the height 

 of from 100 to 130 feet. The form of this species is not 

 so compact as some others, but its beautiful, dark, glossy- 

 green leaves are very attractive. It produces the smallest 

 cones of the genus. 



Var. glauca, Antoine. Differs from the species in hav- 

 ing glaucous leaves. Said to be very striking. 



Var, longifolia, Antoine. The foliage is longer and 

 straighter than the usual form, and it is robust.
