340 REMARKS ON LAURUS CASSIA. 
on account of the aromatic properties of its bark and leaves, — i 
which resemble the true cinnamon, though it is not the 
genuine cinnamon-tree, he seems to have considered himself _ 
quite safe in associating this also, and, therefore, called the — 
three species, this ¢ria-juncta-in-uno plant, Laurus Cassia, and — 
assigned it as the source of the officinal ** Cassia Lignea 2 
cortex," i uA 
After this exposition of the origin of the species Laurus — 
Cassia, it can scarcely be a matter of surprise that no two 
botanists have ever agreed as to the plant which ought to bear 
that name; nor, that none should ever have surmised what. 
plant Linnzeus had constituted the type of his species. It is. 
far from my intention on the present occasion to extend these 
remarks, by tracing the various conjectures that have. been | 
promulgated on the subject; suffice it to say that no one, $0. 
far as I am aware, has taken a similar view as that now set 
forth. It only further remains for me to give some account 
of the three species thus erroneously associated. os 
The first mentioned, Dawalkurundu, ( Linnzus' own plant- 
and the type of the species,) is, I believe, the Laurus involu- 
'erata of Vahl and of Lamarck in the Encyclopédie Méthodique, 4 
and has, in Professor Nees’ Monograph of the Indian Laurine 
(Wall. Plant. Asiat. rariores,) received the name of Tere 
denia Zeylanica, but is the Litsea Zeylanica of a former work.

the other being preoccupied, The slight difference of struc- 
ture does not seem to render a new genus necessary. 
The second and third have both been referred, by & 
same eminent botanist, to his variety of the true cinnamon 
the Cinnamomum Zeylanicum; a, decision to which ] cannot 
subscribe, as I do not perceive that either of these figures are.

The Cinnamomum perpetuo florens appears to me a perfectly
