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

Research Questions
1 Taxonomic Identity
2 Morphological differences: ecological or genetic
3 Feniak Lake: new species
Distribution map of Claytonia in Alaska
Research Methods
-Specimen Review
-Field Collection
-Molecular analysis
-Ecological Niche Modeling
Type Description Review
1) Review of original publication
2) Translate Latin descriptions
3) Request Type Specimens
Variation within genus
C. acutifoliaC. arctica
C. tuberosa
C. scammaniana
C. megarhiza
Variation within speciesC. scammaniana
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…
