2 posites, forming much of the upper subalpine forest in the Western district, 
have generally their trunks bent near the base and extending more or less 
hörizontally. In 3 species the bark is fairly thick, but in the remainder it is 
thin, and in the tree-composites, Dracophylilum Traversii and Libocedrus Bidwilliüi, 
the outer bark hangs in long strips. As with the lowland trees, the species 
are surface-rooting, but the roots do not extend so far laterally nor are they 
raised to the same extent above the ground. Er 
Coming now to the leaves, — 23 species have simple leaves, ı compound, 
4 narrow, 2 cupressoid, ı7 broad, 2 very large (over 20 cm long), 14 medium: 
(5—10 cm long), 4 small (2.5 —5 cm long), 4 very small (less than 2.5 cm long), 
22 thick or coriaceous, 2 thin, ı2 glabrous, 10 tomentose, 2 more or less.
