AGATHIS. 
The leaves of Agathis are directed obliquely upwards, 
their under surface is of a glaucous tint, arising from the 
presence of numerous stomata on their surface. "The whitish 
tint of the surface on which these bodies occur, corroborates 
Dutrochet’s statement, that the white spots are observable on 
sume leaves, owing to the air cotained in the adjacent tissue. 
The leaves of this species are coriaceous lanceolate obtuse. 
They consist of a cuticle, especially dense on the upper or 
stomatous surface, and dense parenchyma, in which the green 
colouring matter is developed. "Through the centre of this 
several parallel vascular fascicles, which do not anastomose 
run. "The central ones of which alone, reach the apex, the 
others terminating at the margins. 
The stomata have generally a transverse direction, and 
have direct communication with the inter-parenchymatous 
spaces. 
The vascular fascicles consist of extremely elongated fibrous 
tissue, ducts and spiral vessels, which occur neither rarely, 
nor in a rudimentary state. It appears to me that none of 
the peculiar tissue exists in the young tissue of Agathis. — 
In the wood, these bodies occur generally in single rows in 
the tissue composing the wood, occasionally in double rows, 
the bodies alternating with each other. 
From the arrangement of certain cells of the cutis and of 
the outer surface of the scales, of young cones, and which
