Origin/Endemic status: Endemic

Taxonomy Comments: Broadly considered, this species includes a variety of morphological forms; a narrower view might hold some to specific levels. Alternatively, the overall intermediate morphology suggests possible hybrid origin of most or all of these entities, perhaps between members of the Intricatae and Apricae series. Generally, leaves are sharply serrate and shallowly incised-lobed; stamens 10-20 per flower and anthers pink to purple; fruit 8-12 mm, red, with soft flesh. The stamen counts vary from 10 in typical C. alleghaniensis to 12-20 in related forms sharing much of the same range.
