"^xcoXthna longiflora Can. is commended by Mr. Frost, above, for its 

 beauty. 'Wicotidna persica Lindh deserves like commendation : a large 

 group of plants of the latter was very abundant in large white and, seen 

 collectively, showy flowers, in the afternoon of August 13. 1833, in the 

 Horticultural Society's Garden: I say afternoon, because the flowers of the 

 tobaccos are usually less beautiful under a midday sun than in the evening 

 and the morning, when, moreover, they efixise a pleasant odour. Of both 

 Wicotidna longiflora Cav. and N, persica Lindl. a notice was given in the 

 last Number, p. 487. 



Calandrinia grandifldra. A fine bed of plants of this species was beautiful 

 in the Horticultural Society's Garden in the summer and autumn of 1832. 

 The flowers of the species of this genus most display their beauty in the 

 heat and bright light of the midday sun. Calandrinia speciosa Lindl., a 

 description of whose charms, and directions for cultivating it, are in the last 

 Number, p. 485., quoted from Dr. Lindley, is there shown to be an eligible 

 species, although a much smaller one, for the same purposes of floral deco- 

 ration. — J. D. 



Art. XII. A Mode of preserving the greatest Number of Pelar- 

 goniums and other Kinds of Green-house Plants through the 

 Winter, in the least possible Space. By Mr. Peter Mackenzie, 

 Gardener to Robert Lewis, Esq., of Wester Plean. 



Sir, 



Gardeners are, in the spring, often at great trouble in col- 

 lecting a number of cuttings of green-house plants, especially 

 of pelargoniums ; and, after these have struck, and the plants 

 thus formed have flowei'ed through the summer, they must, 

 when autumn has drawn near its close, be put into some 

 place of safety for the winter. At those places where there 

 is not proper accommodation for them, the gardeners, having 

 a regard for the plants they liave reared, are often much 

 perplexed in biinging them through the winter. In con- 

 sequence, when the time has arrived at which the plants 

 must be transplanted from the borders into pots, and after 

 the knife has been used freely upon them, they are often 

 crowded together in ill-lighted rooms and other out-houses, 

 where they can scarcely draw their breath, and where num- 

 bers of them die ; and those which survive the winter are 

 few and ill-favoured. To endeavour to remedy this evil is 

 the object of this paper. The plan is a very simple one. 



About the time at which green-house plants are taken 

 from the borders, go over them, and take off what cuttings 

 they can spare (some may be cut to pieces, and made the 

 most of); then take pots about eight or nine inches' diameter, 

 put twenty or thirty cuttings in each, and plunge the pots 

 up to the rim in a hot-bed which has but a slight heat; cover 

 the pots of cuttings with hand-glasses, or a small frame, and 

 in a short time the cuttings will have emitted roots. They 

 may remain there as long as the weather is mild. When
