Herbaceous Peonies. (with a coloured plate of P. decora elatior, lobata, and anemonæflora.)
P. decora.—This is a very handsome species, and, as Anderson remarks, well marked out from all the others by the elegant stateliness of its habit; each stalk accompanied by its horizontal leaves diminishing as they ascend, and terminated by its flower, supported on a long peduncle, exhibits somewhat of a pyramidal figure.  It is clearly allied to P. arietina, although when seen growing side by side with that species the distinction is wide enough for all practical purposes.  In P. decora the leaflets are tripartite, narrow, oblong, blunt, and hairy underneath; flowers medium-sized, purple, red, or crimson.  P. decora var. elatior, well represented in the accompanying plate, is also one of the varieties described by Anderson.  It was first seen in Messrs. Chandler and Buckingham's nursery, and was believed to have been introduced from Holland.  The leaves are much broader than in the type, the plant altogether more robust in habit and more hairy.

(1) On ne devine pas pourquoi cette espèce figure encore sous le nom de fœmina dans l'Ecole de botanique du Jardin des Plnates de Paris, puisque depuis plusieurs années on a supprime celui mas , tout aussi absurde , par lequel on désignait l'espèce appelée aujourd'hui corallina.
