Mr. ANDERSON's Monograph of the Genus Paonia. 285 
jointly responsible: it is possible, I think, that new varieties may 
be discovered, and that future investigation may add to the refc- 
rences which we have given; the work cannot be considered as 
complete, whilst any synonym of those authors, who described 
what they actually observed, remains unapplied ; such additions, 
if they be thought worthy of notice, shall be given hereafter in a 
supplemental paper, should health and leisure be allowed me. 
The first volume of M. De Candolle's Systema Naturale Regni 
Vegetabilis, which has just arrived from Paris, contains the genus 
Pæonia; and as that work must, from its peculiar merit and from 
the great repute of its author, be constantly referred to as autho- 
rity, it will perhaps be considered not entirely useless to compare 
the species of our paper with those of M. De Candolle, and to 
endeavour to reconcile the points of apparent difference. He has 
not arranged his species in the order which has been adopted in our 
paper, but placed them in the following succession: X. Moutan ; 
2. Corallina ; 3. Officinalis ; 4. Peregrina; 5. Lobata; 6. Daurica ; 
T. Albiflora ; 8. Tatarica; 9. Humilis; 10. Anomala; 11. IIybrida; 
19. Tenuifolia; 13. Laciniata. | 
In Moutan he has made the double one the type of his species; 
and under that has referred to our two double varieties; placing 
P. papaveracea as the second variety, and suggesting the eis 
By that it may be a distinct species. 
- Of P. albiflora he makes two varieties only ; his æ, dido by 
ds reference to Andr. Repos. 64, is our P. albiflora æ. vestalis; his 
B. flore roseo is our P. albiflora y. Tatarica, as I conclude from 
his reference to Par. Lond. 78, though the plant there figured 
is described as having ** petala pallide rosea," whilst that with 
* petala rosea," therein noticed as another variety, is either our 
P. albiflora s. rubescens, or one which, if ever it did exist in our 
gardens, is now lost. - M. De Candolle's reference to the Hortus 
Kewensis,
