Diagnosis and jiffinity. 



The plant which most resembles^ this is Cheiranthus ery^ 

 simoides Linn., or Erysimum hieracifolium Linn. Bhrh. (not 

 Jacqu.), or Er. hnceolatmn R. Br. But this latter plant i^ 

 distinguished by its habitat being confined to dry, sunny 

 places, along the wayside, — by its erect stem, distinctly den- 

 tated leaves, and by its white flowers being larger and whiter. 

 Er. hieracifolium Jacq., or odoratum Ehrh. Willd., is also 

 extremely similar, but it has commonly a simple stem, dis- 

 tinctly dentated leaves, golden-yellow flowers, which have a 

 pleasant smelly circular petals, and a two-lobed stigma at the 

 end of the siliqua. Er. repandum Linn, has an almost pro- 

 cumbent stem, tlie flower-branches of which stand opposite to 

 the leaves : it has also lanceolate, angular dentated leaves, 

 and horizontal siliquse. Er. diffiisum Ehrh. has hnear, 

 greyish, slightly dentated leaves, the hairs of which have 

 merely a simple cleft, and the flowers are of a pale yel- 

 low colour, and large. Er. angustifolium Ehrh. has revo- 

 lute, linear, sulcated, entire, greyish leaves, sulphur-yellow 

 flowers, and a long pistillum on the end of the siliqua.
