16 On the Perigynous Insertion of the Stamina of Plants. 
Comarum, Geum, and Rubus: Rosa of all others stands conspi-. 
cuous in this respect, its receptacle, vulgarly called Hip with 
us, being very similar to that of Ficus. In the eleventh Order 
of Leguminosae, this part is again of primary importance, and in 
no genus more so, than the vast Mimosa, which will, I suspect, be - 
most naturally subdivided by attending to its receptacle : ] know 
three species atleast, in each of which its structure is very differ- 
rent. In Cassia the Receptacle is remarkable and persistent, 
whereas the real Calyx is deciduous. In Trifolium it varies most 
beautifully, and the numerous Papilionacee, from Port Jackson, 
will possibly be better discriminated by it. j 
In the two last Orders of Perigynous Corollas, Terebintacee . 
and RAamni, I scarcely yet know a genus except Cneorum : this 
has most clearly both Petala and Stamina hypogyna quite sepa- 
rate from the Calyx. Jer has its Petals equally distinct from 
the Calyx, and cohering slightly at the base with each other. 
Phylica Y think belongs to a very different order: its whole fruc- 
tification is singular, and I know no genus that approaches it but - 
— Penaa: in both I suspect the real Calyx is inferus and 2-phyllous. 
. I have thus, Gentlemen, endeavoured to point out, what I 
. conceive to be a false notion which has misled the very first Bo- 
tanist now living, respecting the insertion of the Stamina in so 
| great a number oe Natural S I fear that I have tired you, 
“ornari enim res ipsa negat :” but I see many around me whose 
; abilities to decide upon far more abstruse and difficult t point in
