This species of gladecress differs in having fruit that are constricted between each seed giving it the appearance of a chain of beads. The seeds do not have wings. The terminal lobe of the leaf is notably larger than the lateral lobes and the petals have a greenish to lavender tint and a small notch at the end. These are very small plants (about 5 cm or less) with the flower on a scape and are found associated with open rocky glade habitat.

Timber removal may be beneficial and even needed to maintain the open character of the habitat for this species. Hand removal of trees in the vicinity of the population is necessary to avoid impacts from timber operations. Exotic pest plants are a threat to this species and should be removed. Avoid creating access to the site through trail or road construction.
