RHAMNUS CLEBURNI ? Lesq.

RHAMNUS CLEBURNI Lesq., Tert. Fl., p. 280, Pl. LIII, figs. 1—3, 1878.

The collections made by Merriam's expedition contain a single broken specimen that may belong to this species, but it is only the upper portion of the blade, and it is impossible to identify this specimen with certainty in the absence of the basal portion. It seems to be this species, however.

Locality.—Cherry Creek, Cook County, Oregon. Collected by Merriam's expedition in 1900 (Mus. Univ. Cal., No. 180).

RHAMNUS ERIDANI Unger.

RHAMNUS ERIDANI Unger. Newberry, Later Extinct Floras, p. 118, Pl. XLVIII, fig. 7, 1898.
