- 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.
