Origin/Endemic status: Native

Taxonomy Comments: C. pumila Pursh has priority over C. tenuifolia Nuttall; the description in Pursh's flora ("a small straggling bush"), and more critically the type specimen, conform to what has more generally been known as C. tenuifolia (Whittemore in Yatskievych 2013). This species is mainly an apomictic triploid.
