A New Hybrid of Asimina (Annonaceae) Based on Morphological and Ecological Data

ABSTRACT Two species of the genus Asimina (Annonaceae), A. triloba and A. parviflora, are well known to occur in South Carolina. Recent work investigating variation in leaf size, flower morphology, and habitat of Asimina in the state shows that a hybrid between the two species exists. The differences in the three taxa are best related to growth form, peduncle length, and outer petal length and width. This new hybrid, Asimina3piedmontana, is hereby described and distinguished from both parents.
