AMESIUM RUTA-JIURARIA. 2'l7 



€ulkxt 



The species constituting the genus Amesium are difficult 

 plants to cultivate : they seem to disapprove of the attentions 

 of the gardener, to loathe his waterings and his syringings, to 

 despise his composts, and utterly to eschew the confinement of 

 a hell glass. Out of doors, the wall rue succeeds best on a 

 garden- wall; in-doors, it must be kept in a well- ventilated 

 greenhouse, and planted in a small pot filled with broken brick 

 and old crumbled mortar : water should be supplied very spar- 

 ingly. It may be observed that the want of success which ordi- 

 narily accompanies the attempt to cultivate these little ferns, is 

 often attributable to injuries inflicted on their radicles and cau- 

 dices in removing them from their original localities ; gTeat 

 care should therefore be taken in conducting this difficult pro- 

 cess : if permitted, it is best to remove the bricks one at a time, 

 and to replace them as soon as the ferns are secured.
