THE GREEN-HOUSE. 



propagated in this way ; a young shoot of any rare 

 sort being grafted on a tuber of a Lardy kind. Baron 

 Tsclioudi, an ingenious French horticulturist, informs 

 us that he has grafted the love-apple on the potato, 

 the melon on the gourd, and the cabbage on the cau- 

 liflower. (See Essai sur la Greffe de VHerhe, par 

 le Baron Tschoudi, Sfc. 1819.) 



Subsect. 5. Propagation of Green-house Plants hy 

 their hams. 



The propagation of plants by their leaves is com- 

 paratively a recent discovery. It takes place in nature 

 with a few plants, such as the Dionce^a, Scilla, 

 &c., and with the hairy Ladies'-smock {Cai^ddmine 

 hirsuta), a native of this country. All the improve- 

 ment which art has hitherto made on this natural 

 mode of propagation, is to take off the leaves when 

 they are fully grown, and instead of dropping them 

 on the earth at random, to lay them on their backs on 

 moist earth shaded either by position or by covering, 

 or, what is generally preferable, by a little fresh moss 

 strewed over them. All the culture necessary till the 

 young plants form themselves on the edge of the 

 leaves, is to keep the moss and earth below of a regu- 

 lar degree of moisture, and exclude bright sunshine. 

 The following green-house and hot-house plants may 

 be propagated in this way, covering the more delicate
