bats, crocks, sandstone, and old lime rubble, mixed in with the soil. 

 As a proof of its comparative hardiness, a plant of it grew in England 

 luxuriantly on an eastern wall, out of doors, during the summer and autumn 

 of 1865." 



This charming creeper is a native of New Grenada, where it is cultivated 

 in gardens under the name of Courouba. It found its way into Europe a 

 few years since through M. Van Volxem, a Belgian traveller, after whom it 

 has been named. — Florist. 



Clematis rubella and Lanugifiosa Candida. — The former was raised by 

 Messrs. Jackman of Woking, to whom we also owe those fine varieties, 

 yackmanni and rubro-violacca, figured in a former volume, and which were 

 the forerunners of a new race of clematises. Rubella, one of the finest 

 of these, has been several times exhibited, and has received first-class 

 certificates both from the Royal Horticultural and Botanic Societies. Its 

 flowers are of a rich, velvety, reddish-violet, and are stated to be more con- 

 stant in having five or six petals than any of the other varieties. Lanugifiosa 

 Candida is white, slightly tinged with purple towards the edges of the petals, 

 and will prove useful for mixing with the richer-colored varieties. It is 

 believed to be of Continental origin. The mode of cultivation pursued by 

 Messrs. Jackman in the case of these and other varieties is thus stated by 

 Mr. George Jackman, jun. : " When we put our specimen clematises out, 

 we plant them permanently out of pots in the open ground. In pots they 

 will flower freely, but will not produce flowers in equal number or of so 

 fine a quality, because the clematis, having a fleshy root, cannot take up 

 sufficient moisture to develop its flowers so finely as in the open ground. 

 The soil they luxuriate mostly in is one composed of rich manured loam, 

 and, when possible, fine calcareous sand. They should be pruned back in 

 the spring, about February, leaving a quantity of good breaking-buds : but 

 there is this difference, — some kinds will only flower on the old, well- 

 ripened wood of last year's growth; therefore discretion must be used. C. 

 Standishii, Fortunei, and all the varieties of azurea grandijlora, are of this 

 character; while others, such as the hybrid seedlings of which C. JackmaJini 

 is the type, — rubro-violacea, rubella, Prince of Wales, and all the viticcllas, 

 — will grow and flower quite as well and as vigorously on the spring's 

 growth as the other varieties do on the older wood. After pruning, the
