There were also hundreds of lilac pinks, magenta. pinks and plain magentas, most of which were very unattractive. Many closely resembled Banksi. Typical varieties were 'Archduc Ludovico,' 'Athlete,' 'Beaute de Twickel,' 'Jules PirIot,' 'La Ville de St. Denis,' 'Morris,' 'Princess Louise,' 'Reine Amelie,' 'Reine des Fleurs,' 'Triomphe de Vandermaelen,' and 'van Houttei.' All these varieties proved, in Holland and France, easy to propagate in comparison with the later introduced Japanese varieties. Which varieties bearing European names were actually raised from seed in Europe and which were Chinese varieties renamed is not too definitely established.

Comments on and corrections to this list are invited. Information is particularly desired on the varieties believed to have been originated in Italy by Casaretto, Burdin, and others, for all attempts to learn something of these men have ended in failure.

Van Houttei. Double (Casaretto) offered by Haage & Schmidt 1864; Van Houtte 1873; Krelage 1867; Dessert 1899, 1905; Paillet 1889.

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:
Van Houtteii, large, double, carmine...

Chinese Tree Pæonies. — Pæonia Moutan.
These are the most splendid and showy of all flowering shrubs, and among the most rare.
The flowers are mostly fragrant, and all are double, unless denoted otherwise.  They are perfectly hardy, and will withstand the winters of our most northern States and the Canadas.  They bloom in May, ten to fifteen days before the Chinese Herbaceous varieties.
The following are imported varieties.  We can supply extra size plants of most of the varieties, at a moderate advance in prices.

Pivoines en arbre.
Dans les lots de M. Guérin Modeste, rue des Boulets, à Paris, et de MM. Verdier père et Charles fils, il y avait en outre d'admirables variétés gagnées en Europe, et qui, par le volume et la perfectibilité des fleurs, laissaient bien en arrière les introductions de M. Fortune.  Nous n'en citerons que quelques-unes, qui faisaient l'admiration de tout le monde, et que tout amateur doit posséder.
