Taxonomy Comments: A rare, ambiguous taxon that is not known to be represented by collection since 1925, possibly extinct. The combination of localized occurrence, pubescent leaves, 10-20 stamens, reddish anthers and 2-3 pyrenes with slightly pitted inner sides suggest an interserial hybrid origin, possibly involving C. calpodendron and a member of the Intricatae series.
