become effaced. The small specimen represented in fig. 13 is loosened from 

 the stone, in part, at least, and appears filled with a dry irregularly wrinkled 

 ovule half decayed. 



Habitat. — Golden, Colorado.

Seeds(?) obovate or oblong, rounded and enlarged on one side, narrowed 

 on the other to a point or a pedicel, one to one and a half centimeters long 

 and five to .six millimeters broad, distinctly striate in the length. These 

 fruits are not rare, always immersed into the stone, convex, or half-flattened. 

 They resemble large glumes. Fig. 4 ^ of pi. xxxv and fig. 14 of pi. Ix seem 

 narrowed into a pedicel, and are slightly scythe-shaped. 



Habitat. — Black Buttes, Wyoming, common. Evanston, Wyoming, rare.

The composition of these vegetable organs is not well ascertained. 

 They appear like wings of a small, round carpel attached at the base. The 

 wings are broadly cordate, obtuse; the one in fig. 18 surrounded by a flat 

 border. 'Jlie carpel is inflated and of about the same form. Its i)osition at 

 the base of the wing may be casual, this being perhaps an inflated pod from 

 which the carpel has been expelled or detached by compression. 



Habitat. — Black Buttes, Wyoming. 



Carpites laurinciis, £p. ncv. 

 Plate LX, Figs. 20, 21. 



Berries small, nearly round, short-pointed, about five millimeters in 

 diameter, surrounded by a thin, shelly epicarp. They closely resemble the 

 fruits of Tetranthera sessiliflora (pi. xxxv, figs. 8 c and d), and especially those 

 of pi. xxxiv, fig. 1 c. They may represent the same species, for they merely 

 differ by their shape, which is rather round than oval, and by their smaller 

 size. They are from the same locality. 



Habitat. — ;Evanston, Wyoming.
