to say nothing of the singular apparatus about the root, that 

 however difficult it may be to find proper generic character* 

 to distinguish them by, we feel quite unwilling to give up a 

 name by which these plants have been so long generally 

 known. 



The roots of all the species of Dentaria are more or less 

 scaly. In our plant the scales are fleshy, cordate, concave, 

 at first white, but turning to a dull purple with age. 



A hardy perennial. Propagated by dividing the root. 

 Flowers in April, May and June. Communicated by Ro- 

 bert Barclay, Esq. of Bury Hill.
