The genus Claytonia L. (Spring Beauty) is well recognized around Alaska for its attractive flower. Despite its charismatic appearance, there is much

confusion around the species delineation of Claytonia in Alaska.

The Genus: Claytonia

Limnia• 3 ovules• annual

Review of type specimens and figures

Field work!• Noatak National Preserve– Collection of potentially new species

• Eagle Summit– Collection at Scamman’s original type location

• Aleutian Islands – Specimen for comparison to C. arctica type

• North Slope

Future Work

- Genetic Analysis- Ecological Niche Modeling- Greenhouse Experiment

And hopefully clarification…
