more commonly about the middle. The pinnules are enlarged 
more or less at or above the middle, decurrent to the next 
pinnule below by a broad auricle, and cut in above the base by 
an acute sinus. The midrib is represented by a very thin line. 
Numerous glandular dots are seen between the veins, doubt- 
less representing a mineral deposit. 
Formation and locality: Cherokee shales, Lansing.

The form with long narrow pinnules described from the 
Cherokee shales of Missouri under the above varietal name is 
found also at Lansing. It differs from the species in the more 
narrow pinnules, hardly at all enlarged above the base, and 
in that the acute sinus above the base is almost or entirely 
lacking.

Fronds very large, tripinnate or possibly quadripinnate at 
the base. Rachis strong, finely longitudinally striate. Pri- 
mary pinne open, contracted to a pointed apex at the summit. 
Secondary pinnze very deciduous, rather open, contiguous, 
linear-lanceolate, obtusely pointed at the summit, 7 to 20 cm. 
long, 12 to 40 mm. broad. The primary pinne are replaced 
above by simple pinnee, the larger of which are pinnatifid, the 
smaller with undulate or entire borders. Pinnules open, in- 
clined, straight or slightly arched backwards, decurrent, more 
or less connate at the base, separated by an obtuse sinus, bor- 
ders almost parallel, sometimes slightly enlarged at the middle, 
rounded at the apex, 6 to 25 mm. long, 4 to 10 broad; terminal 
pinnule short, oval or linear. Median vein distinct, con- 
tinuing quite to the summit; secondary veins attached at an
