302 UNITED STATES GEOLOGKJAL SURVEY— TERTIARY FLORA. 



CARPITES, Schp. 



Prof. Schiuiper, in his Palcontologie VegeUile, proposes and admits the 

 name of Carpites as a distinction for the fruits and seeds of dicotyledonous 

 species from those of the Carboniferous. This distinction seems right, in 

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

 now to the name of CarpoUthes. 



Carpites liiientiis!, Newby. 

 Plate LX, Figs. 1-1 d. 

 CarpoUthes Hneatus, Newby., Notes on the Later Ext. Fl., p. 31. — Lesqx., Annual Report, 1871, p. ^95. 

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



Prof Newberry has given (his 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 Evanston, but has the same characters. TKese, nearly two 

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

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

 related to the fruits of some Palms, though tlie 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 Corylus, 

 their relation is as yet unascertained. 



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



Carpites oviformis, 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 lineate, but somewhat rough. 

 It is much like the fruit of Prunus Scoifii, Heer, figured in Arct. FL, i, pi. 

 viii, fig. 15 a, only more obtuse. 



PIabitat. — Golden, Colorado. 



Carpites triang:iiIosiis, sp. nov. 

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



Dropes small, triangular, obtuse, eight to ten millimeters long, four to six broad below the 

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



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

 species, of the same generic division. These drupes resemble those of a 

 Prunus, but are much smaller.
