Notes
VARIATION. Various leaf-forms of this plant have been described as distinct species. The size and shape of the lobes, however, appear to depend on environmental conditions, the plants growing in dry, open situations having many small narrow lobes, while those with a few large lobes are found in relatively damp, shady places.
