THE GREEN-HOUSE. 



house, — a soil of loam with a little peat, and little 

 water when not in flower. They may all be propa- 

 gated by cuttings, cut across at a joint, and planted 

 in the same sort of soil the parent plant grows in, 

 with the addition of a little sand. They require 

 neither a bell-glass nor to be placed on heat, but 

 merely shading from the direct rays of the sun. 



There are a number of other Pelargonia with 

 bulbous and tuberous roots ; but we have not enu- 

 merated them because they are more curious than 

 showy, and less easy to manage than the others. 

 There are also a number of new genera, which Mr. 

 Sweet and other botanists have formed out of what 

 were formerly Geraniums or Pelargoniums ; but as 

 these are chiefly curious plants, we have made no se- 

 lection from them here, as they will be found noticed 

 in the general catalogue (Chap. IV.) It may be 

 proper to state that these genera are as follow, 

 viz., "^Campy^lia, Hoarea, Monsonia, ^JenMnsdnia^ 

 Phymetanthus, ^Otidia, Dimacria, Isopetalum, "^Ci- 

 conium, and Grielum, besides the old genera Erodium 

 and Geranium. Of these we would recommend 

 Phymetanthus as being the old Pelargonium tricolor 

 and hicolor, and one or two species of the others which 

 we have marked with an asterisk, provided there be 

 room in the green-house. 



The culture of all the Pelargoniums which we 

 have enumerated, is perhaps easier than that of any 

 green-house plant whatever. All that is necessary is 

 to furnish them with regular supplies of water, and
