close, as it dift'ers in beiiijj;" niucli broader, with an acuminate apex and 

 five nerves. Z. MeeMi, Lesijuereux,* from the Post-Laramie beds of 

 Colorado has similar teeth, but differs in being much broader and in 

 having five nerves. 



The species is represented by about half a dozen specimens in a 

 fairly good condition, except as relates to the finer nervation.

The only specimen of this species is the one figured, which agrees 

 closely with certain of the examples figured in the Arctic FloraA The 

 figure here referred to agrees almost exactly in size and uervation with 

 our specimen. Fig. 4 of the same plate is also similar, being only uuich 

 larger.

 Plate IX, figs. 10, 11. 



Leaf thickish, firm, approaching deltoid in general outline;, deeply 

 heart-shaped at base, 5- (possibly 9) lobed, or 3-lobed, with the termi- 

 nal larger lobe again 5- (i>ossibly 7) lobed; lower lobes at right angles 

 to the midrib, above them being a central lobe which is provided with 

 five (or seven) smaller lobes; margin all around provided with coarse 

 blunt teeth; midrib straight, thick; secondaries, 4 pairs, the lower pair 

 at right angles to the midrib or falling a little above or below a right 

 angle; upper pairs at an angle of 45°, all entering the points of the 

 lobes; lower pair of secondaries i^rovided with about 5 pairs of terti- 

 aries, which either enter or send branches to the teeth; upper secon- 

 daries sending out as many branches on the outside as there are teeth; 

 nervills mainly percurrent, forming regular quadrangular areas between 

 the secondaries and their branches; finer nervation mostly obsolete. 



The collection contains numerous specimens of this very interesting 

 plant, some of them being nearly perfect. The largest specimen appears
