CHEILANTHES AND ISOETES IN INDIANA 113 
ization since the report was made may have extermin- 
ated it. Further, the writer purchased all of the Indiana 
specimens contained in the Schneck herbarium, and this 
fern was not in the lot. From a consideration of the 
preceding facts, it is believed that Schneck did not find 
his specimen in Indiana, but in one of the adjoining 
counties of Illinois, which has rocky ledges. 
On June 29, 1915, the writer found this species in 
Perry County about six miles east of Cannelton on the 
top of the high rocky bluff of the Ohio River. It was 
noted but once, and was located on the top and near 
the edge of a high perpendicular ledge of rock. The 
Specimens formed a mat over an area about two feet 
ong and a foot and a half wide. 
On July 10, 1915, I again found this species in Martin 
County in the crevices of a rocky bluff along White 
River about five miles north of Shoals. The rocky 
ledges at this place are locally known as the McBride 
bluffs. Here it is sparingly found in isolated tufts. It 
is of interest to note that Polypodium polypodioides (L.) 
Hitche. covered large areas of the perpendicular ledges 
at this place. This is the most northern location for 
the latter species in Indiana. 
The genus Isoetes was not known in Indiana until I 
found Isoetes foveolata A. A. Eaton in Harrison County, 
June 25, 1915. This species was found in abundance 
in a low woods four miles south and one mile east of Pal- 
myra. It formed a mass about four feet wide and 
twenty-five feet long. It was located in a long ago 
abandoned logging road through a thick woods of tall 
trees. The trees nearest were Liquidambar, Quercus 
palustris, Nyssa sylvatica and Acer rubrum. The only 
herbaceous plants nearby were Ludwigia palustris and 
amolus floribunda. 
An additional species of Isoetes was found in Craw- 
ford County on Oct. 12, 1916. It was located in a small
