20 DESCRIPTIONS OF FOSSIL PLANTS. 



Specimens from Cherry Creek, Wasco County, Oregon, collected by 

 Oapt. Charles Bendire, U. S. Army. Age probably Eocene (Laramie 

 group). 

 Rhamnus obovatus Lx. 



Three specimens; Museum number, 2579. 



Rhamnus Dechenii Web. 



Two specimens; Museum number, 2575. 

 Rhamnus Cleburni Lx., var. 



A large fragment, merely differing from the normal form by the 

 nervilles more oblique nearly at right angles to the medial nerve and! 

 slightly more distant. The form of the leaf, of which one side is pre-, 

 served, is conformable to that of the figures of the species in Lesqx. (Cret. 

 and Tert. FL, PL liii, tigs. 1,2), made from specimens from Golden, Colo- 

 rado. 



One specimen ; Museum number, 2580. 



Magnolia lanceolata Lx. 



One specimen ; Museum number, 2515. 



Andromeda protogaea Ung. 



One specimen ; Museum number, 24L'.'>. 

 Aralia digitata Ward. Plate xi, Jig. 4. 



Leaves small, palmately five lobed to the middle, trinerved from above 

 the base, either cuneiform, subcordate, or prolonged into a short tri- 

 dentate pelta ; lobes linear lanceolate, denticulate in the upper part, 

 separated by narrow, obtuse sinuses; secondaries numerous, campto- 

 drome or craspedodrome, entering the teeth in the upper part of the 

 lobes. 



This very hue species is represented by four nearly entirely preserved I 

 leaves in Ward's Synop. of the Flora of the Laramie Group, PI. xlviii, 

 figs. 10-12, and PI. xlix, fig. 1. From these figures the leaves appear ex- 

 tremely variable in size, the whole leaf (fig. 12) being only 8£ om long, in- 

 cluding a thick petiole more than 2 cm , with lobes 3 1 '" long and l cm broad, 

 while another figure (PI. xlix, tig. 1) represents part of a leaf at least 

 16 cm long with lobes 10 cm long and 5'" broad above the middle, the 

 lobes being generally slightly narrowed from the upper part toward the 

 sinuses. 



The relation of this species is like that of A. gracilis and .1. notata 

 Lesqx., of the Laramie group and especially with A. Saportanea Lesqx., 

 of the, Dakota group. The specimens from Cherry Creek have the lower 

 part of the leaf destroyed. 



One specimen ; Museum number, 2121. 



Aralia notata Lx. 



One specimen ; Museum number, 2426.
