66 CULTIVATION. i

 necessary, serve to tie the stems to, with green -

When the beauty of the flowers is over, and 

 the greater number have lost their petals, the ^ 

 awning and frame, if it be a moveable one, 

 should be taken away, the stoppers put on the 

 trunks, and the hoops again fixed in their places j 

 to allow of occasional covering against excessive 

 rain. All the seed-vessels should be cut off as 

 soon as the petals drop ; because, as seeds are not 

 wanted from the fine flowers, and as this part of 

 the plant exacts a considerable portion of the 

 vigour of the system, it is only a waste of it, if 

 expended on an unnecesary production. It is 

 perfectly consistent with physiological facts, that 

 this dismemberment should have the effect al- 

 leged. It has been already shewn, that there 

 is an intimate connection between the oviparous 

 and viviparous organization of bulbous-rooted 

 plants — a reciprocity of action, balancing the 

 crescive powers of either. From the moment 

 the seed-vessel is broken off, the viviparous prin-
