Specific Character. 



CHEIRANTHUS mutabilis foliis lanceolatis acuminatis ar- 

 gute ferratis, caule frutefcente, iiliquis 

 pedunculatis. Ait, Hort. Kew. v. 2. p. 

 395- 



The prefent fpecies of Cheiranthus, unknown both to 

 Miller and Linn^us, was firft; defcribed in the Hortus 

 Kewenfis of Mr. Aiton, who informs us that it was intro- 

 duced to the Royal Garden in 1777, ana " found wild in the t 

 Ifland of Madeira by Mr. Masson. 



Its chief merit as an ornamental plant confifts in its early 

 flowering; its bloflbms which are fhewy contribute to enliven 

 the green-houfe in March and April ; on their firft expanding, 

 they are white, in fome plants (for they, are fubje£t to great 

 variation) inclined to yellow, in a few days they become 

 purple j to this change of colour obfervable alio in the 

 Cheiranthus maritimus already figured, it owes its name or 

 mutabilis. 



In fheltered gardens at the foot of a wall, we have known 

 this fpecies furvive a mild winter ; it feems indeed to be 

 almoft as hardy as the common ftock ; it is moll commonly 

 however kept in the green-houfe. 



The ufual way of propagating this fpecies, which is or 

 ready and quick growth, is by cuttings, which mould be put 

 into the ground as foon as the plant has done flowering; 

 thefe if properly treated will become handfome plants to 

 place in the green-houfe at the approach of Winter, and to 

 decorate it the enfuing Spring; in like manner may the 

 green-houfe be annually recruited with many fimilar plants 

 to great advantage. \
