Lacjena tjicoi.or. Two-coloured. (Bot. Reg. 50). Orchidaeese. Gy- 

 naiidria Monandria. From Guatemala ; by Mr. Hartweg found at an elevation 

 of 7010 feet above the level of the sea. The habit of the plant is much like 

 that of the Peristerias, having pendulous racemes of flowers, ten to twelve in 

 each. Petals and sepals yellowish-green, with white margins. Labellum of the 

 same colour, with a large dark blotch, and a few spots of the same. The under 

 side of the lip is of a purplish-blue. 



Othonna tuberosa. Tuberous rooted. (Bot. Mag. 4038.) Composite. 

 Syngenesia Necessarian. From the Cape to the Royal Gardens at Kew. The 

 root is much like that of a Cyclamen, having a short neck, from whence proceed 

 three or four stems six or eight inches high. Each flower is produced solitary ; 

 terminal yellow, near two inches across. It. is a showy little plant. 



Rhipsalis brachiata. Opposite-branched. (Bot. Mag. 4039.) Cacteae. 

 Icosandria Monogynia. From Buenos Ayres to [the Glasnevin Botanic Garden, 

 Dublin. Small plants bloom profusely, each blossom being about three quarters 

 of an inch across, of a greenish-yellow. 



Salvia prunei.i.oides. Prunella-like Sage. (Pax. Mag. Bot.) Labiatse. 

 Decandria Monogynia. From Mexico. It has been found perfectly hardy in 

 this country. The plant spreads by means of underground stems, which de- 

 velop shoots rapidly that speedily rise [to the height of eight or ten inches. 

 The foliage is not coarse, and a leaf is about two inches long by one broad. The 

 stems are produced closely but not crowded. The flowers are produced in whorls, 

 forming racemous spikes. Each blossom is about three quarters of an inch long, 

 of a bright blue. It is a very pretty dwarf plant, suited for a bed, or border, in 

 the flower-garden, and well merits a place in every one. It may be had of the 

 general nurserymen.

QUERIES. 



On Heating a Greenhouse. — Your reply to a Correspondent, who subscribes 

 himself a 4i Suburban Novice,"' in your last Number, on the subject of heating 

 a greenhouse, is very generally interesting. But allow me to hope that in your 

 next you will oblige us with some detail a little more practical and explanatory. 

 A slight sketch of the apparatus would be very desirable. 



I believe I am right in supposing, that if the hot water-pipes are introduced 

 into the greenhouse, the fire may be at any distance (Yes), and that it is not 

 necessary that the water in them should be kept actually boiling (Certainly 

 not). Now, if this be correct, would it not be possible to contrive a cheap 

 moveable apparatus, which might be removed when not in use. It might con- 

 sist of a small boiler (or pot) of tin 'or zinc, having horizontal pipes, and so 

 constructed that a small flame placed beneath it might be sufficient to keep the 

 water at a temperature approaching to boiling, without the necessity of resorting 

 to all the trouble and expense of bricklayers in setting boilers in brickwork, and 

 constructing expensive flues, &c. As the temperature required in winter would 

 be only just sufficient to keep out frost, would you kindly enter into particulars 

 as to how this can be most readily effected by those novices who do not keep a 

 regular gardener, but who are content to enjoy their greenhouse plants most 

 effectually by waiting upon themselves. I like this kind of independence, and 

 therefore I ask the favour of you to describe in your next Number (for the 

 season is rapidly advancing) how this may best be done. 



I earnestly hope that the occasional notices upon this subject, promised by 

 your Correspondent in the number of the Cabinet for February last, p. 33, will 

 not be omitted.

 p. 33, will favour us as desired by W. S. A. — Conductor.],
