Nbuhaiiina imbricata. — The flower stems rise to about two feet high, anil 

 terminate with a flower in size and form similar to that of a single Tuberose, of 

 a very deep rich velvet colour. It well deserves a place in a collection of 

 bulbous plants. 



Cyiitoceras reklexa. — This plant was at first named Hoya coriacea, but 

 now altered. It is blooming freely, in the way of H. carnosa. The flowers are 

 white in the centre, and yellow to the edges. Hanging in pendulous heads, of 

 twenty in each, gives it a very interesting appearance. Tae leaves are thick, 

 each about four inches long. 



Lilium speciosuii punctatum, eight feet high, having forty flowers expanded, 

 is in most beautiful condition, growing in the open border of the conservatory. 



L. sPEciosuu album is equally vigorous, and as profuse in bloom.

QUERIES. 



On Heating a Greenhouse by Gas-light. — It was mentioned, not long ago, 

 by a correspondent of your Magazine, in one of the southern counties, that bis 

 greenhouse was sufficiently heated throughout the year by a single caudle. 

 After reading it, it occurred t) me that gas might possibly be applied with suc- 

 cess for the same purpose ; but not bei ig acquainted with its capability of con- 

 veying heat, or scientific enough to proportion the expense of using it, com- 

 pared witli the usual methods of obtaining heat by steam, &c, I should be glad 

 of some information on the subject, if yourself or any of your readers think it 

 deserving of attention. The heat from a jet of gas might be increased by in- 

 closing it in something like a stove, allowing sufficient air for it to burn freely. 

 I am aware that gas could not be obtained in many situations ; but when a gas- 

 pipe passes near a greenhouse, I am inclined to think it might be made avail- 

 able without being too expensive.

 respondent, please to give me a little instruction on the culture of Lisianthus 

 Russellianus in an eaily number of your valuable work.-*

On the Double Yellow Rose. — Would Elizabeth, of Ensham, or Herts, 

 who describes the Double Yellow Rose growing at Albury Hall, favour the sub- 

 scriber with one or more cuttings of this delightful plant P She proposes trying 

 it on different situations and soils in her garden, the natural soil being clay. 

 She will be happy to communicate the result of any expeiimeat. Address M. D., 

 care of Mr. Thomas, Royal Oak Hotel, Alloa, N. B. 



On a Rockery. — A constant reader of the Flour iji.tural Cabinet will feel 

 much obliged if any of your correspondents will give her hints for the formation 

 of a rockery in a situation where no advantages can be derived from the nature 

 of the grjund, being merely a flat lawn ; also what plants are best suited for 

 growing in such a place, taking into consideration the northern climate, at the 

 same time the aspect is south-west, and well sheltered by wood. Plenty of peat 

 soil and white spar-stone can be obtained. An answer in an early number will 

 greatly oblige
