Cardamine debilis DC.

Description

A polymorphic sp. not fully resolvable into distinct vars without breeding and cultural tests, owing to the interplay of genetic and habitat factors. It is closely related to , which is naturalized and possibly hybridizes with it. The two vars described below show clear-cut differences. A third, more complex, group is also described. Names are not given in view of the uncertainty as to the type.
