stiff, 1 to 4 cm long, at the apex abruptly bent so that the pod becomes 
more or less cernuous. Sepals narrowly oval, acute to somewhat obtuse, 
white scarious margined, about 2 mm wide by 6 mm long. Petals about 
1 cm long by 5 mm wide, obovate, the apex emarginate to the depth of 
about 1,5 mm. Pods cylindric, 2,5 to 3 mm in diameter, 1 to 1,5 cm 
long, arcuate with the apex curved upwards, yellowish white, lustrous, 
the teeth in dehiscence erect, about 1 mm long, narrowly acuminate. 
Seeds reddish-brown, flattened-globose-reniform with a very narrow sinus, 
quite roughly papillose, about 0,8 mm in diameter, — Ohio: Garretts- 
ville; along the gorge of the Rocky River, Cuyahoga County (R. J. Webb, 
23. VI. 1907, 25. VI. 1909). — This variety, as exemplified by the specimens 
now at hand, has the longer pods of variety oblongifolium with the more 
dense villous-pubescence of villosum and is almost as densely viscid- 
pubescent as is the typical Cerastium vulgatum L. In fact, it almost 
appears as though there might be here a case of hybridism, the inter- 
gradation being so complete.

X (1910), p. 180. — Pinnules linear, lanceolate, or oblanceolate, more or 
less branched; growing with the type; rocky wooded hillsides, Wayne 
County, Ohio (Fig. 1). — In the latter part of August, 1909, in company 
with Mr. R. J. Webb, of Garrettsville, and Mr. A. N. Rood, of Phalanx, 
I visited Woodworth's Glenn, in Portage County. — A clear rapid flowing 
Stream very suggestive of trout has cut out a small ravine through the 
sub-carboniferous (?) sandstone. In some places this ravine is quite narrow 
and the walls almost perpendicular. — The ordinary Fragile Bladder Fern 
grows in abundance upon these rocks. A hasty glance revealed the fact 
that it differed very materially from the ordinary form. The apexes of 
the frond and the tips of the pinnae are branched two to four times, 
acuminate, obtuse or emarginate. — The plant grows plentifully in the 
partially shaded ravine and the differences from the normal type of frond 
seem to warrant the name:

P. 181, c. fig.2. — Apex of frond branched, thebranches often dividing again; 
obtuse or acuminate, pinnae linear, lanceolate, broadly triangular, acum- 
inate, acute or obtuse often branching into two or more irregular seg- 
ments; in part on sandstone rocks, Woodworth's Glenn, Portage County, 
Ohio,
