Aquilegia vulgaris var. speluncarum Lacaita (Ranunculaceae): an enigmatic columbine from the Campanian Apennines, S Italy

摘要

The name Aquilegia vulgaris var. speluncarum, for a little known rupicolous columbine described by Lacaita from the southern Apennines in 1911, is lectotypified and the taxon identified with A. champagnatii, a species described from Picentini massif in 1981. The relationship of the taxon and its diagnostic characters are briefly discussed. It is concluded that it is actually conspecific with A. ottonis and best recognized as a separate subspecies, for which the name A. ottonis subsp. speluncarum is validated.
