History of the Sandal Wood. 
Sydney, New South Wales, November 21, 1863. 
I have just read a paper in the ‘ Intellectual Observer,’ * On Sandal Wood

1862. 4to, pp. 35, tab. 3. 
The principal topics referred to in this brochure are, the condition of 
the leaf-bud in the resting stage, as well as during expansion, the yearly 
growth of the shoots, the phyllotaxis of the bud-scales, the form of the 
leaf, its nervation, its lobes, and its :estivation. Dr. Móhl devotes some 
space to a subject that may be of interest to our readers, viz. the me- 
thod of distinguishing the two reputed species of Oak, Quercus sessili- 
flora and Q. pedunculata, the one from the other, by the buds and twigs, 
as well as by the general form of the leaf and of the tree, thus render-

The bud of Q. sessiliflora tapers from below upwards, and is tra- 
versed by five well-marked longitudinal ridges. The bud-scales are 
arranged in spiral cycles, the direction of which is very oblique, so that 
the successive scales of the same series only overlap one another to a 
slight extent at the base, but each scale covers over the lower half of 
the one placed immediately above it, in the adjacent cycle. The bud
