tachments, such as might be expected to be present if the speci- 

 men was part of the cuhn of a sedge or grass, although it might 

 represent an internodal portion. Its general appearance is more 

 suggestive of a piece of the petiole of a palm leaf. Whether or 

 not it had anything in common with the monocotyledonous leaf 

 fragment last described is impossible to determine, or even to 

 surmise. The two specimens are of interest merely as repre- 

 senting the class of vegetation to which they apparently belong. 



Dicotyledonae 



(Choripetalae) 

 Order JUGL AND ALES 

 Family Juglandaceae 



Genus Hicoria Eafinesque 



Hicoria pseudovata n. sp. 



Plate 30, figures 1, 2 



'^Hicoria n. sp. ?" Holliek, Svmmiary Kept. {loc. cit.), p. 134. 



Leaflets oblong-ellii3tical or oblong-lanceolate-ovate in shape, 

 about 11 centimeters in length by 5 centimeters in maximum 

 mdth, tapering to base and apex ; margin closely and uniformly 

 denticulate ; nervation simply pinnate ; secondary nerves irregu- 

 larly spaced and disposed, subtending various angles, of about 

 45° and less, with the midrib, curved upward toward their ex- 

 tremities, where they give off tine nervilles in the form of 

 branches from the under sides, that terminate in the adjacent 

 marginal denticulations. 



These specimens apparently represent sessile leaflets of a 

 compound leaf closely similar to those of certain existing spe- 

 cies of hickory, especially Hicoria glabra (Miller) Britton, and 

 H. ovata (Miller) Britton. Figure 1 apparently represents two 

 fragmentary, overlapping lateral leaflets, attached to a broken 

 leaf stalk. These present somewhat the appearance of being 

 confluent at their bases, but this appearance is probably due to 

 distortion and overlapping. Figure 2 represents a single de- 

 tached lateral leaflet.
