Convallaria is a circumboreal genus with three closely related taxa; 2n = 38 in all (FNA 26, W). Their nomenclature has a somewhat tortured history. Gandhi et al. (2017) attempted to clarify the situation; they rejected the name C. pseudomajalis Benth. for C. majuscula, which they treated as a subspecies of the European C. majalis L. However, W has retained C. pseudomajalis as a species. Although Cr suggested that these are indistinct plants derived from plantings of majalis, its widely scattered distribution on southern Appalachian mountains is hard to explain in terms of just 200-300 years of dispersal from cultivation. Moreover, these plants appear more closely related to the Asian C. keiskei Miquel than to majalis. In Ky. majiuscula is known only from a few sites in BELL on Cumberland Mt. near the border with Va. Several records from other counties in Ky. and fro central Tenn. appear to be based on misidentified majalis (SERNEC May 2020). The species is generally more robust than majalis, except that inflorescences are relatively short (FNA 26, W, Gandhi et al. 2017): leaf blades averaging 15-35 x 5-13 cm (versus 10-15 x 3-5 cm), with relatively distinct veins (versus faint), but often yellowing in late summer (versus green until frost); rhizomes absent or long-creeping (versus short-creeping), the individual above-ground shoots usually at least 15 cm apart (versus 5-10 cm apart); flowering scape less than half as long as the leaves (versus more than half); longer bracts of the inflorescence 8-20 mm long (versus 4-10 mm), usually at least as long the pedicels (versus shorter); tepal midribs green (versus white); seeds oblate or lenticular (versus almost globose).
