lous, but he only cut the Knot, for his character is good for no- 
thing. Some time after the publication of his work, Sir Joseph . 
Banks brought me specimens of Leptospermum and Philadelphus 
in fruit from Kew, desiring me to show him any difference: this 
[could not do. Being well persuaded; however, that two such 
dissimilar plants could not belong to one genus, the following 
spring I forced the dwarf variety of Philadelphus, and compared 
them when in flower: all difficulty immediately ceased; for I 
saw that in Leptospermum the Calyx and the Corolla were alter- 
nately inserted by a very short Unguis in the same line of the 
Receptaculum; but in PAiladelphus the Calyx has a broad dilat- 
. ed base, so as completely to include the Corolla, which is insert- 
ed in a separate line nearer the Pistillum: these differences, now 
that we know them, may always be observed, even in the fruit ; 
for the scars where the Calyx and Corolla were attached remain, 
affording another proof that the part underneath cannot possibly 
bea Calyx. Melastoma in the eighth Order perhaps alone consti- 
tutes a Natural Family; but as it is a Tropical genus, we can 
scarcely expect to see it well divided in our days: in one species 
from Jamaica, which flowered with me at Chapel-Allerton, there 
was no Calyx whatever, but in place of it, a very narrow line 
similar to what is left in Eucalyptus after its Involucrum falls off. 
Lagerstremia in the ninth Order has a very peculiar Insertion, 
like nothing I now recollect but that of Sophora tetraptera : in 
both these genera the receptacle is very large and hollow, and 
the scars of all the various parts inserted in it remain very deep 
and conspicuous. The tenth Perigynous Order contains under | 
the name of Rosacee eight sections: in the first, our common 
Cherry and Apple Blossom, though generally passed over by Bo- 
tanists, afford incontrovertible proofs of the presence of a re-, 
ceptacle distinct from the Calyx, as well as Fragaria, Potentilla, 
Comarum,
