Robert Fortune, the great explorer of the Royal Horticultural Society, made four trips to China and introduced many fine plants to England. In 1846, he brought twenty-five of the finest tree peonies ever to come out of China. Among these were 'Atrosanguinea,' 'Berenice,' 'Bijou de Chusan,' 'Dr. Bowring,' 'Globosa,' 'Glory of Shanghai,' 'Lord Macartney,' 'Pride of Hongkong,' 'Robert Fortune,' 'Samarang,' and 'Zenobia.' These were enthusiastically received and quickly propagated, so that both British and continental nurseries cataloged them in some quantity in the 1860's.

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 distinct new Chinese Varieties obtained by Robert Fortune; and, as they are the most rare and valuable varieties, the prices will be regulated according to their size.

Le Jardin des Pivoines en Chine, par Robert FORTUNE (1)....
J'allai visiter, après le jardin du Stwï (South garder) ), celui des Pivoines Mouian (Moutan gardens), situé à 5 ou 6 kilomètres ouest de Shanghaï, au milieu d'une vaste plaine consacrée à la culture du cotonnier. Je rencontrai, sur ma route, de nombreux coolies (2) qui portaient, au marché, des paniers remplis de Pivoines en arbre en pleine fleuraison. A mon arrivée au jardin, j'y vis une grande quantité de ces plantes, dont les fleurs étaient surprenantes de beauté; mais les plus remarquables sont celles à fleurs pourpres et lilas. 11 y en avait une très petite, à feuilles élégamment découpées, portant des fleurs pourpre foncé velouté, — comme la Rose de Toscane, cultivée en Angleterre, — et qui me paraît une espèce très-distincte ; les Chinois la nomment black (Pivoine noire), et c'est elle, je crois, que le docteur Lindley a décrite dans le Journal de la Société sous le nom de Pœonia atrosanguinea. Une autre espèce, à fleurs très grandes, et nommée en chinois Tse, c'est-à-dire pourpre, est probablement la Pivoine à mille pétales , qui est réservée pour le jardin de l'Empereur. Enfin , il en est une troisième nommée Lan ou Pivoine bleue, dont les fleurs ont la couleur de la Glycine de Chine ( Wisteria sinensis). Il y en a plusieurs autres à fleurs pourpre, très distinctes des précédentes et qui sont tout aussi belles...

MOUTAN PAEONIES INTRODUCED FROM CHINA.
BY MESSRS. STANDISH AND NOBLE, BAGSHOT NUBSEBY.
Of the many remarkable plants imported by us from China, these, if judged by the size and beauty of their flowers, are among the most attractive. In the magnitude of their individual blossoms, in the diversity and richness of their colours, as well as in the profusion in which they are produced, nothing remains to be desired. The following sketch will afford an idea of their general characters. First, of colour: of white there are examples unsurpassed in intensity and clearness by any other flower, not excepting even the old double white Camellia. Of rose colours there are many shades, as well as of purples, and one rivalling the richness of the Tuscan rose. Then there is a pale blush, light red, deep red, salmon colour, primrose, peach colour, and crimson; with various other tints and combinations of these already mentioned. Some of the light-coloured ones have the bases of their petals deeply stained with red or purple; others are delicately shaded. Most of the flowers are very double; some are, however, only semi-double, the latter generally have the petals stained as described. In shape many are finely cupped; more resemble the finest rose, and others have anemone flowers. Of the last named, a white and a deep red are fine examples. In size, too, they are remarkable; some of the flowers produced last season, and from small plants, measured eight, ten, and twelve inches across.....
