Wabash County specimen was found about a mile southeast of Lagro on 

 Hanging Rock, which is 84 feet high. It is probably extinct there now 

 since that place has become a picnic ground.

2. Pellaea glabella Mett. Smooth Purple Cliffbrake. Map 36. This 

 species was not separated from the preceding species even in Britton and 

 Brown, Illustrated Flora, edition 2, published in 1913. Pickett (Amer. 

 Fern Jour. 4: 97-101. 1914) wrote an article entitled "A peculiar form of 

 Pellaea atropurpurea Link" and set forth the differences at length, but he 

 did not give it a name until in a later article (Amer. Fern Jour. 7: 3-5. 

 1917.) Butters (Amer. Fern Jour. 7: 77-87. 1917) took up the subject 

 and listed the specimens at the Gray Herbarium to show the range of the 

 two species. 



This species has the habitat of the preceding but it is less frequent. Pel- 

 laea atropurpurea is regarded as the southern representative of the genus 

 in our area and has a mass distribution to the south of a line connecting 

 Kansas and Connecticut. Pellaea glabella is regarded as the northern 

 representative of the genus in our area and has its mass distribution north 

 of that of Pellaea atropurpurea.

13. CHEILANTHES Sw. Liffern 



Fronds bipinnate, hirsute, especially beneath; hairs straightish, jointed, and often of 



a rusty color, especially on the stipe 1. C. lanosa. 



Fronds tripinnate, tomentose with white hairs. (See excluded species no. 10, p. 1020.) 



C. tomentosa. 



1. Cheilanthes lanosa (Michx.) Watt. Hairy Lipfern. Map 37. I 

 have found this species on the exposed cliffs along White River at the 

 McBride Bluffs about 5 miles north of Shoals in Martin County. I have 

 also found it in three places in Perry County. It is infrequent on the 

 stones capping the high cliffs along the Ohio River about 5 miles east of
