ARAUCARIA. 43 



Mr. Duncan, who first discovered this species, says that 

 the seminal leaves of Araucaria Rulei pass through six stages 

 before they are fully elaborated, and those stages resemble the 

 foliage of all the others of the genus from Araucaria Cookii to 

 imbricata. The leaves on old trees, however, are regularly 

 and evenly produced aU round the branches ; and are broad, 

 flat, and incurved or pressed against them, so as to lie 

 imbricated over each other, and thus give to the branches 

 considerable bulk.

 Leaves alternate, scattered all round the sheets, those on the 

 larger ones compressed, spreading, or curved, from half an inch 

 to one inch long; those on the branchlets of young plants much 

 more slender, shorter, and more numerous, incurved, and some- 

 what four-sided ; those on the adult trees closely imbricated, 

 rounded, and almost inlaying upon the branchlets. Branches 

 in regular distant, horizontal whorls, slightly bending down- 

 wards, and again ascending towards the extremities ; branchlets 

 in two rows, along the sides of the branches, frequently
