THE PINE SUB-FAMILY. 265 



6, A, excelsa. Brown. NORFOLK ISLAND PINE. The 

 most tender species, but growing much larger than the 

 others, almost rivalling in grandeur the " Giant Trees of 

 California." Specimens have been measured that were 

 225 feet in height, with trunks 11 feet in diameter, and en- 

 tirely destitute of branches to the height of 80 or 100 feet. 

 The branches are in regular whorls, and the globular cones 

 are about 6 inches in diameter, and produce very large seeds. 



7. A, Rulei, Mueller. Another of the newer Australian 

 species that is quite tender in England. It forms a dense, 

 compact tree about 50 feet in height, with very numerous, 

 closely imbricated, dark glossy-green leaves, and very 

 large, globular cones, having broad scales, terminating in 

 narrow, lance-shaped projections or points an inch long. 



1O. DAMHARA, Rumphius. 



Dioecious, having globular, axillary cones, and solitary, 

 coriaceous, persistent leaves. The carpellary scales are 

 devoid of bracts ; the ovules solitary, and not adherent to 

 their base. According to Gordon there are five known 

 species, and three that are uncertain. 



We note this tender genus and the following to warn 

 those who may be disposed to try them of their true char- 

 acter, as well as to give those who wish to grow them 

 under glass a list of the species, with some indications of 

 their character. The descriptions of these will necessarily 

 be brief. 



1. D. australiS; Lambert. Is a tree from 120 to 150 

 feet high, and a native of New Zealand.
