Twin-flowers, surplus corolla lobes and/or calyx tips, lacking spurs and
the like are quite frequent phenomena in many Pinguicula species. Usually
they are environment effects (Linne called them 'humour of nature'). The
only hereditary 'deformities' I observed are bifurcations of the spur and
filled flowers.
