Original diagnosis/description

Pedunculate cupules. Cupule ovate, composed of four ovate valves fully enclosing two trigonal nuts. External surface with spiny appendages occasionally bifurcate near tip. Peduncle long (up to 2.5 times as long as the cupule), thickened near junction with cupule. Nuts triangular in cross section, ovate, elliptical, to obovate in face view, with a narrow wing or flange developed along the three angles of the nut. Sepals arising from apex of nut and surrounding the three styles.


This species is named to honor David Langevin whose love of the McAbee site has lead to the discovery and conservation of numerous important fossil specimens.
