Lectotypification and an Emended Description of Rosa ×fernaldiorum

Abstract

ABSTRACT The recently named nothospecies Rosa ×fernaldiorum was incorrectly described as a hybrid between R. carolina and R. nitida. We show that the proper hybrid formula is R. nitida × R. palustris. The purported holotype was found to consist of three specimens mounted on two sheets; we here choose a lectotype from this material, correct the hybrid formula, provide a more complete description than in the original place of publication, and cite additional specimens.
