ON THE CAMPHOR -TREE OF SUMATRA. 
of this tree; we are not, however, certain of the correctness of 
his figure. 
The leaves seen by us differ from those of Miller's specimens, 
which we saw in 1850 in the British Museum, (which are much 
larger,) and from those of Colebrooke's drawings and descriptions ; 
the largest leaves of the latter being 0,175 long, and 0,05 broad. 
But this difference is perhaps explained by ours being smaller be- 
cause they are on flower-bearing branches. They most resemble 
the description given by Houttuyn. 
Most authors speak of stipules (Colebr. Korth.) We have not 
seen them, and suppose that our specimens have lost them ; we 
must therefore refer our readers to what the two last-mentioned 
botanists have written on the subject. 
The calyx has many modifications in the form of its base and 
wings, as w T ell as in the direction of those wings, which are some- 
times nearer to each other, or more modified or reflexed. The 
great diversity which we have observed in our specimens per- 
suades us that there is no reason for accepting more species. 
Colebrooke has seen and drawn objects in full growth. In the dif- 
ferent states of developement in which we saw this calyx, we al- 
ways found natural cavities in its tissue, chiefly in the woody 
part. In the interior it is resinous, and emits a smell of tur- 
pentine. 
We have not space for further descriptions of the crown, the 
stamens, and the fruit. The albumen seen by us was in some of 
Marsden's specimens in the British Museum, preserved there in 
spirits ; it agrees entirely with the figure and description given by 
Gaertner. In the specimens at our disposal, which were not pre- 
served in spirits, the albumen was consumed. For these specimens 
we are much indebted to the liberality of Mr. Robert Brown. 
Through lack of young specimens, the structure of the ovary has 
been till now 7 but imperfectly known. The reason is, that natural- 
ists have not had the opportunity of getting specimens at the time 
of the devlopement of the flowers. 
Dryobalanops Camphora, Coleb. must be the plant mentioned 
by Grimm, Rhync, Valentyn, and Rumphius. It is the same as 
that mentioned by Miller, and which M. Rademacher presented 
to Houttuyn. It belongs undoubtedly to the same genius as
