Royal horticultural.—May 22nd.
...A similar award [Silver Banksian Medal] was made to Messrs. Kelway & Sons, Langport, Somerset, for a group, consisting on nine boxes of Tree and other Pæonies. Amongst the Tree varieties we noticed Elizabeth (rosy pink), Caroline (blush and pink centre), Comte de Flandres (satiny pink), Mrs. Lowe (carmine pink), Lumen (white and pink centre), and Ida (rose-pink, almost white at the margin). All these were doubles; but Moutan simplex was single, and white with a purple base.

The Tree Pæony. 
...For the last twenty years or longer we have had to look to our French neighbours for new sorts of Tree Pæony, for since they have taken the work of hybridising and raising seedlings in hand they have supplied us with all the finest sorts.  Until now the list is long- too long, in fact, for names are given where very shadowy differences exist.

The Best Tree Peonies.
The following list contains some of the very best varieties of tree Peonies or Moutans at present in cultivation; I obtained it from my friend M. Charles Verdier, of Paris, who makes Peonies his special study; among them, as will be seen, are few novelties, but M. Verdier states that the newer varieties are generally inferior to the older kinds:
Carolina, bright salmon...

Pivoines arborescentes.
A la dernière floraison des Pivoines, nous avons remarqué, dans la riche collection de M. Guérin-Modeste, rue des Boulets, 7, à Paris, quelques variétés tout à fait extrâ, que nous croyons pouvoir recommander aux amateurs.  Ce ne sont pas des dernières nouveautés; beaucoup se trouvent déjà chez les horticulteurs qui s'occupent de ce beau genre.  Ces belles plantes, les voici:
Carolina.  Fleurs carnées, plus pâles au sommet des pétales.
