Jane McGary wrote " It has been mentioned that the name Colchicum parnassicum is misapplied in cultivation to C. laetum hort. However, the Archibalds offer seed of a documented collection of C. parnassicum, which I am growing though it is not mature enough to flower yet, so in spite of being misapplied in gardens it is apparently a valid name -- at least at some point in the unsatisfactory nomenclature of this genus........" Reference to the Kew Monocot Check List, see http://apps.kew.org/wcsp/… shows Colchicum parnassicum to be an accepted name with an Homotypic synonym of C. lingulatum var. parnassicum, and a Heterotypic synonym of C. neopolitanum. C. laetum is also accepted with the Homotypic synonym of C. byzantinum var. laetum. David Nicholson in Devon UK Zone 9b
