in the leaves of the one being oval, the other fharp- 
pointed ; and that the nerves afe limited at the bottom 
in the Cinnamon, but not fo in the CafTia : for as to 
the femper jlorcns , mentioned by Burman, that mud: 
undoubtedly be common to both. 
Now as to the different fhape of the leaves, we 
know how often this happens by feminal varieties, 
and from the age of plants, as in the leaves of holly 
and ivy ; and that even the fhapes of leaves vary 
greatly on the very fame plant, and fometimes on 
the fame branch ; as in the alh, and many other 
plants, the leaves of the young fhoots are more oval 
than thofe on the old boughs, which are generally 
more pointed. But this variety is much more fre- 
quent in the plants of warm countries. In the falfa- 
fras, part of the leaves generally near the bottom of 
the plant are plain, whilft the other leaves are di- 
vided into three lobes or fegments. I have obferved 
great difference alfo in the leaves of almoft every 
one of the American oaks. 
In the Virginian cedar, the berries of the fame plant 
produce fome plants with juniper leaves, and others 
with leaves like the favin j and fome plants with 
both leaves growing o.n the fame plant. 
I mull obferve, that Burman has, in his figures 
of the two plants before mentioned, made them 
extremely different. In that of Ceylon he has made 
all the leaves oval ; and, to make the difference 
greater, has drawn the rudiments of the berries ; to 
which he has added the flower, or part of it, at the 
top of the flyle or rudiment of the fruit : and in 
that of Malabar he has drawn the flower growing in 
the umbel.
