SELLARDS.] Fossil Plants, Upper Paleozoic, Kansas. All 
a long slender-pointed apex, attached to the rachis by the 
rather strong midrib; auricled, the lower auricle the largest, 
extending slightly over the rachis, attached at an open angle 
but curved up decidedly at the narrow apex. Nervation close, 
fine, but usually distinct. Midvein rather strong at the base, 
where it measures about 1 mm. in the larger pinnules, sloping 
gradually toward the apex, becoming a thin line in the upper 
part of the pinnule, but continuing to the apex, slightly turned 
down at its union with the rachis, striate, with four or five 
distinct or undulating strize traceable to about the middle of 
the pinnule. The lateral veins leave the midrib at a very acute 
angle, continue for some distance very close to it, then curve 
out strongly, fork three or four times, and reach the border 
at an obtuse angle, with a slight forward inclination on reach- 
ing the border. Veins of the basal part, especially of the 
auricles, curved back strongly; those of the narrow apex 
oblique, forked once or twice. Veins numerous, counting 36 
to 40 at the border. Lamina slightly rugose but not scaly or 
hairy. 
The species is close to Neuropteris aspera Lesqx.,78" espe- 
cially to the specimens referred to that species by Lesquereux 
in the third volume of the Coal Flora. The characters sepa- 
rating N. hastata from N. aspera seem to be the peculiar shape 
of the pinnules of N. hastata, and their remarkably slender 
acuminate apex. The venation of N. aspera is, according to 
Lesquereux’s description, much finer than that of N. hastata.

Fronds very large. Polypinnate, primary and secondary 
rachises thick, striate, dichotomous, often bearing at or near 
the forks sessile oval cyclopteroid pinnules, sometimes or- 
bicular or cordate at the base. Pinnz alternate or suboppo- 
site, open or oblique, broad or triangular in outline, overlap- 
ping one another, bipinnate in the greater part of their length, 
simply pinnate toward their tip. Ultimate pinnez alternate or 
subopposite, open or oblique, sometimes slightly arched up- 
wards, linear or linear-lanceolate, with borders touching or 
287. Coal Flora, vol. 1, p. 121, pl. 13, figs. 10-12, and vol. 3, p. 736, pl. 96.
