lanceleaf springbeauty

Publication: Fl. Amer. Sept. 1: 175, plate 3. 1814.

Origin: Native

selected vouchers: WTU

Notes: Taxonomy follows FNA, with the varieties in H&C split among two species, Claytonia lanceolata s. str. and C. multiscapa.

FNA5: "Some differences of opinion exist regarding the relationships of Claytonia lanceolata and C. rosea. The work of D. K. Halleck and D. Wiens (1966) and J. S. Shelly et al. (1998) provides ample justification for their recognition as distinct species."
