*Melilotus albus Medikus. Common name: White Melilot, White Sweetclover, Honeyclover. Phenology: Apr-Oct. Habitat: Fields, roadsides, disturbed areas. Distribution: Native of Eurasia.
Origin/Endemic status: Eurasia
Taxonomy Comments: The similar M. albus and M. officinalis are apparently incompatible (Isely 1998) and differ in less obvious ways than flower color; they should not be synonymized, as was done by Kartesz (1999, 2010, 2022). Other differences useful in the determination of faded herbarium specimens are given by Isely (1998) and Yatskievych (2013): corolla 3.5-5 mm long, the wing petals about as long as the keel, ovaries narrowed at base, mature fruits with a network of raised nerves (M. albus) vs. corolla 5-7 mm long, the wing petals generally longer than the keel, ovaries noticeably stalked at base, mature fruits with a pattern of cross-nerves or merely with irregular cross-wrinkles (M. officinalis).
