Discussion

Garden escapes of Chelone lyonii are reported from Connecticut, Maine, Massachusetts, and New York. Chelone lyonii can be distinguished from other members of the genus by its longer petioles, rounded to truncate leaf bases, and white to light pink staminodes. It is sometimes confused with C. obliqua, especially where C. lyonii is found with leaves narrowed to the base. Chelone lyonii can be distinguished from C. obliqua by wider leaf blades, longer petioles, more strongly keeled corollas, shorter abaxial corolla lips, and longer staminodes. Chelone lyonii has been proposed as a diploid progenitor for the allopolyploid C. obliqua (A. D. Nelson 1995; Nelson and W. J. Elisens 1999).
