FLORA OF THE DAKOTA GROUP. 71 



narrowed base; the borders are deeply regularly undulate from below the 

 middle; the two lower pairs of lateral nerves thinner than those above 

 and more open arc camptodrome, the other craspedodrome. The basilar 

 border seems to pass over the top of the petiole as in Menispermites. 



Hab. — This species is not rare in Kansas. The specimen figured was 

 communicated by Prof. B. F. Mudge. No. 698 of the National Museum. 



H a in a 111 e 1 i t e s quercifolius, sp. nov. 



Leaf oblong, coriaceous, lanceolate, rounded to the base, blunt at the apex, undu- 

 late on the borders; nervation pinnate, deep; hiteral veins close, oblique, craspedodrome, 

 branching on the lower side. 



The leaf has great likeness to Dryopyllum fQuercusJ latifolium, pi. iv, 

 fig. i. It is about the same length but narrower, only 5i centimeters broad 

 in the middle, as in the preceding species; the two lower pairs of secondary 

 nerves are thinner, less oblique, more open than the eight others above. 

 These slightly curve in passing to the borders and enter, like the divisions, 

 the outside curve of the undulations. 



Hab. — Bluff Creek. Ellsworth County, Kansas. Chs. Sternberg. There 

 is only one specimen (No. 62a of the Museum Comp. Zool., Cambridge). 



H a in a in e 1 i t e s ? cordatus, ep. nov. 

 Plate IV, Fig. 3. 



Leaves large, thickish, broadly oval-oblong, deeply narrowly cordate at base, 

 obtusely dentate; nervation pinnate; lateral nerves oblique, slightly curved in passing 

 toward the borders, much branching on the lower side, craspedodrome. 



This fragment represents a leaf about 12 centimeters long, 7 to 8 cen- 

 timeters broad. It is undulate-dentate all around, pinnately nerved, with 

 the secondary nerves at equal distance, and parallel, except two pairs of 

 smaller ones attached to the base of the lower lateral nerves. Of these, 

 the upper curves downward, branching and entering the borders by its 

 apex and by its divisions, the lowest, simple and marginal, follows the 

 nearly auricled basal borders. Nothing is seen of the areolation. Some 

 simple parallel nervilles continuous and at right angles to the veins are 

 seen in the upper part of the leaf, which by its facies and some of its 

 characters resembles a Viburnum. 



Hab. — Near Fort Harker, Kansas. Chs. Sternberg.
