{ 
‘Roots tuberous, tubercles dentoid; leaves ternate, rare- | 
ly digitate or pseudopinnate, opposite, alternate, or in : 
threes. Stems iform, simple; flowers dilute purple, 
rarely yellowish. Mr. R. Brown in Hort. Kew. 4. p. 101. 
unites this genus with Cardamine and probably with pro- 
priety; at the same time the habit of Dentaria is very dis- 
tinct.
