four plants have bloomed, and strange as it may appear, (you 

 know the parent to be a large white,) one of those which flow- 

 ered is a deep rose color and perfectly double. It perhaps 

 may be desirable to say that the soil used was sand, loam, and 

 leaf mould, in equal proportions, and watered with pure river 

 water.

The above experiments, by so successful a practitioner as Mr. 

 Buist, will at once set at rest all doubts respecting the time usu- 

 ally required to vegetate seeds of roses, of the Chinese varieties. 

 We hope Mr. Boll, or other of our friends, will give us the re- 

 sults of experiments upon the vegetating of hardy rose seeds, 

 which, Mr. Buist thinks, (see vol. Ill, p. 315,) require a much 

 longer time to vegetate, than the Chinese varieties. The exper- 

 iments now detailed confirm Mr. Boll's statement, (III, p. 216.) 

 But Mr. Russell, who doubted the blooming of roses, at the ear- 

 ly age of four months from the seed, intended his remarks to ap- 

 ply to hardy varieties. 



The sport of the progeny of the Lamarque rose, noticed by 

 Mr. Buist, is very remarkable. Such things are frequent in the 

 dahlia, carnation, &.c., but are probably rare in the rose. A de- 

 scription of the above named seedlings, would undoubtedly be 

 acceptable to our readers, should they prove to be valuable 

 kinds. — Ed. 



Art. IV. On the Cultivation of the Trevirdnn. coccinea. 

 By the Editor. 



One of the prettiest plants of which our gardens or green- 

 houses can boast, in the fall of the year, is the Treviruna coc- 

 cinea, or Cyrilla pulchella of Herit. It flowers from the month of 

 August to October, and when well managed presents a gay and 

 brilliant appearance, by the profusion of its scarlet corols, through- 

 out that season of the year. It is an old plant in English collections, 

 though it is not very generally disseminated in our gardens — cer- 

 tainly not half so widely as it should be — but we attribute this 

 to be, as with many other fine things, from a want of a knowledge
