arisino- at a point well iil)()ve the base of tho blade, passing up at an 

 acute anole to near the upper part of the leaf, and here they l)e('ome 

 tiiin ami join with the e(iually thin secondaries from the upper part of 

 the midrib; each of the large secondaries with several thin loops on 

 tlie outer side; nervilles numerous, thin, crossing between the midrib 

 and strong secondaries, mainly percurrent though irregular; finer 

 nervation producing rather large blocks. 



The example figured is the only one found in the collections. It 

 lacks only the extreme upper portion. The length was about 6.5 cm., 

 exclusive of the petiole, which is 1.5 cm. in length. The width of 

 the blade is 2.5 cm. at the broadest point, which is slightly above the 

 middle. 



'This species is wholly unlike anything before reported from the 

 beds at Bridge Creek. It is perhaps nearest to certain forms of 

 (J. Srheuclizerl of Heer, being, for example, hardly to be separated 

 from a leaf figured by Ludwig" in his Fossile Pflanzen aus der altesten 

 Abtheilung der Rheinisch - Wetteraurer Tertiar- Formation. This, 

 however, is not the typical form of C. Scheuchzeri., and I prefer to 

 describe it as new rather than unite it with an anomalous leaf that has 

 been referred to an established species.

Sterile flowers of large size; calyx lobes of firm texture, broadly 

 obovate, oval, or nearly circular in shape, considerably overlapping, 

 obtuse and rounded at apex, truncate or slightly narrowed at the 

 sessile base; nervation strong, consisting of some six or eight nerves 

 of equal strength, the central one passing apparently to the tip of the 

 calyx lobes and having two or three branches at various distances 

 which anastomose with it some distance below the apex; other nerves 

 diverging and joining by broad loops with several series of smaller 

 loops outside; nervilles producing c^uite large irregularly (Quadrangu- 

 lar areas in which there are often free veins.
