Description. — " Leaves short in proportion to width, very obtuse, at- 

 tached by a short slightly twisted pedicel, broadly elliptical or oblong in 

 shape, broadest near the base, slightly inequilateral at base; nerves fork- 

 ing once or twice near the base and then parallel to near the summit, 

 where they are a little crowded together, the outer ones ending in the 

 margins a little below the apex." — Fontaine, 1890. 



The description of N. incequilateralis is an alliteration of that of the 

 preceding N. oMusifolia. It is based on a single specimen. Veins are 

 twenty-two in number, much thicker than in Nageiopsis, and like those 

 in iV. acuminata, which has also been referred to Podozamites. They 

 converge toward the tip of the leaf, which is missing in the specimen. 

 Leaf pedicellate at base. 



N. montanensis, from the Kootanie at Geyser, Montana, is based on a 

 single detached leaflet with nineteen or twenty veins, convergent in the 

 obtuse tip. There is absolutely no ground for including it in Nageiopsis. 

 The incequilateralis specimen comes from Kankeys, Virginia, and o6- 

 tusifolia was found near Potomac Eun and at Cockpit Point, Virginia. 



These imperfect forms are suggestive of Podozamites affinis (Schenk) 

 Schimper ^ of the Wernsdorfer schichten, but are not representative 

 enough for accurate comparison. 



It seems probable that Podozamites ellipsoideus Sap.^ represents addi- 

 tional occurrences of this species in the JSTeocomian and Albian of Portu- 

 gal, and that the forms from the Neocomian of Japan which Yoko- 

 yama^ identifies with Podozamites pusillus Velen. are the Asiatic rep-
