302 UNITED STATES GEOLOGKJAL SURVEY— TERTIARY FLORA. 



CARPITES, Schp. 



Prof. Schiinper. in his Paleonlologie Vcgctale, proposes and admits the 

 name of CarpUcs as a distinction for the frnits and seeds of dicotyledonous 

 species from those of the Carboniferous. Tliis distinction seems rigiit, in 

 order at least to reduce the very numerous specific names appended until 

 now to tlic name of Carpolithes.

Plate LX, Figs. 1-1 d. ' , i J- • 



Carpolithes Hneatus, Newby., Notes on the Later Ext. Fl., p. 31.— Lesqx., Annual Report, 1871, p. 295. 

 Frnits nearly globular, slightly pointed, irregularly thinly striated in the length. 



Prof Newberry has given this name to a fruit figured in the plates of 

 the Miocene flora of Fort Union, but not described. It is a little smaller 

 than those of Evan.ston, but has the same characters. These, nearly two 

 centimeters in size, much resemble hazel-nuts, and could be referable to 

 Corijlus, but for their thinner, shelly envelope. By this character, they are 

 related to the fruits of some Palms, though the epicarp is twice as thick as 

 in those described (pi. xi and xiii). As no Palm leaves have been found at 

 Evanston, where these nuts are very abundant, and none either of Coryhis, 

 their relation is as yet unascertained. 



Habitat. — Evanston, Wyoming; above coal {Dr. A. C. Peak). 



Carpites oviforinis, sp. nov. 

 Plate XXX, Fig. 6 a. 

 Fruit exactly ovoid, ten millimeters long, six broad in the middle. 



This small nut is apparently a hard drupe, as it is not flattened by com- 

 pression. Its surface is neither striate nor lineato, but somewhat rough. 

 It is much like the fruit of Prunus Scotlii, licer, figured in Arct. Fl., i, pi. 

 viii, fig. 15 a, only more obtuse. 



Habitat. — Golden, Colorado. 



Carpites triaiigiilosiis, sp. nov. 

 Plate LX, Fig. 4 ; Plato LXII, Figs. 19, 20. 



Drnpes small, triangular, obtuse, eight to ten millimeters long, four to six l)road below the 

 middle, grooved by a deep middle lino from the point to the base, .smooth or indistinctly lined. 



I consider figs. 19 and 20 as a small variety, or perhaps a diflerent 

 specie.*!, of the same generic division. These druues resemble those of a 

 Prunus, but are much smaller.
