ticular would in many instances be productive of gratifying im-

Chinese Primroses. — It is sometimes a matter of difficulty to get 

 seed from these; select the best plants, thin out the flower stems, 

 stake securely those that are left, and set them out in the sun, at- 

 tend carefully in supplying them with water, under these conditions 

 they will be likely to mature plenty of seed. D. D. 



GARDEN MEMORANDA. 



Mr. Editor. — A few days ago, having an hour or two to spare in West 

 Philadelphia, I called at two of the principal gardening establishments there, 

 those of Mr. J. F. Knorr, and of Mr. W. W. Keen. Being rather in your 

 own neighborhood, I was surprised to find so many things worthy of note 

 with which the readers of the "Florist" are unacquainted. You will, I hope, 

 pardon me for the attempt to drag out the light from under your bushel. 



The former gentleman's establishment is anything but an extensive one ; 

 the ground occupied by it is perhaps under an acre; it has a small green- 

 house, hothouse, propagating house, and rose house. In these there are pro- 

 bably congregated a greater stock of valuable novelties than in any similar 

 space in the Union. The hothouse contains many choice Orchideie, among 

 which I noticed the rare Dendrobium Dalhousianum and Cambridgeanum. 

 There were probably ten or a dozen species of (Eschynanthus, M. albidus be- 

 ing in flower; its white fringed corolla gives it a very distinct character, 

 but it will be generally thought inferior in gaiety to many other kinds. The 

 very rare and valuable Medinilla magnifica had two of its large clusters of 

 flowers far advanced towards expansion; Nematanthus Morrellianus was also 

 in bloom, the flower has a purplish tinge, though in other respects resembl- 

 ing N. longipes. 



In the greenhouse Bignonia picta, a very well-grown specimen, was in 

 flower ; the corolla is large, white, thickly set with purple lines ; it will make 

 a favorite climber for a warm greenhouse. Jasminum gracile, an old but 

 not much known species, with profuse white flowers and small privet-like 

 leaves, was abundantly set with flower, &c. Here also was a very fine Cam- 

 panula Yidalii, looking more like a shrubby Cotyledon or Crassula than a 

 member of the bell flower fraternity. A very choice assortment of the new- 

 est Cinerarias were in bloom, and afforded an illustration of the great pro- 

 gress in beauty this pet plant is making ; they were all mostly two-colored, 

 with petals broad, and the whole flower forming a perfectly circular outline. 

 I took Adela Villiers, Mrs. Sydney Herbert, and Vicar of Wakefield as three
