FOSSIL FLORA. 691 



2.8 rin. broad. When entire, it must have been uearl}' or (juite 10 cm. 

 ill Iciiiitli. 



Tliis species is evidently related to ('ari/a (Hicoria) aiitlqiKnuni Ne\vl»\-., 

 and it may possiblv l)e an anomalous form of that species. It ap))ears to 

 ditfer essentially, however, in being very nuu'h smaller, less unequal-sided, 

 and in liaving larger and less numerous teeth. The secondaries are nuich 

 the same in both, except tliat they are more decidedly camptodmnie in 

 ('. (infifi/iorinii. 



It is also suggestive of Jnf/lm/s i/if/clhi Ung., as identified liy Ward^ from 

 the lower Yellowstone River. 



Habitat: Nortliea.st side of Crescent Hill, o])posite small pond, at an 

 altitude of about 7,500 feet; collected by F. H. Knowlton and G. E. 

 Culver, July 27, 1888. 



HlCoKIA CULVEKI n. sp. 



V\. LXXXIIl. tis. 7. 



Leaflets thin, slightly injccpiilateral, rather long obovate, narrowed from 

 above the middle to a long wedge-shaped base, and upward to an acuminate 

 apex; margin toothed from above the lower third, teeth flat, olituse; mid- 

 rib slender; secondaries aljout 10 pairs, alternate, irregular, camptodrome, 

 arching u])ward and joining by a broad curve, with l)ranclies outside enter- 

 ing the teeth; intermediate secondaries occasional, joining the secondary 

 below; nervilles verv irregular, l)roken; finer ner\ation forming irregular 

 meshes. 



The line specimen tigured appears to l)e a terminal leaflet, as it is only 

 slightly inpequilateral. It is perfect, except at the apex It is pi-eserved 

 for 8 cm., and was ])robably il.5 or 10 cm. long. It is 2.7 cm. l)road at the 

 Avidest point, whit'h is high above the middle. From this point it tapers 

 reo'ularly to the liase and aj^jjears to ])ass rather abru})tly to an acuminate 

 ■d\)ex. 



This species has the same shape and arrangement •dullhiis hciKj'irci Lx.,- 

 from John Day Valley, Oregon, but difters in the serration of the margins 

 and hi the flner nervation. It seems likely that Lesquereux's species is a 

 Hicoria rather than a lihus.
