A biosystematic analysis of theCaltha leptosepala(Ranunculaceae) complex in the Rocky Mountains.: III. Variability in seed and gross morphological characteristics

摘要

Part three of a biosystematic study of theCaltha leptosepalacomplex in the Rocky Mountains involves analyses of embryology and gross morphology. Data obtained from both the natural populations investigated and from dried herbarium material support the premise that only one species,Caltha leptosepala, can be taxonomically justified for the Rocky Mountains.
