22. HAIRY LIP FERN 



Cheilanthes vestita (C. lanosa) 



Growing on rocks, Southern New York to Georgia. Six to fifteen 

 inches high, with brown and shining stalks. 



Fronds. Oblong-lance-shaped, rough with rusty hairs, twice- 

 pinnate ; pinncB rather distant, triangular-ovate, cut into oblong, 

 more or less incised pinnules; fruit-dots roundish; indusium 

 formed by the reflexed margins of the lobes which are pushed back 

 by the matured sporangia. 



Till a few years ago the most northern station for 

 the Hairy Lip Fern was supposed to be within the 

 limits of New York City. The plant was discov- 

 ered, in 1866 or 1867, on Manhattan Island, near Fort 

 Tryon, growing on rocks with an eastern exposure. 

 If one should visit this station to-day he would find 

 himself at iQ6th Street, in the city of New York, 

 some two hundred and thirty-three yards west of 

 the Kingsbridge road, and I fear there would be no 

 trace of this to us rare fern. 



Since then the plant has been discovered close to 

 the Hudson River at Poughkeepsie. 



Its narrowly oblong, dull-green fronds, more or 

 less covered with red-brown hairs, which give it a 

 somewhat rusty appearance, spring from the clefts 

 and ledges of rocks.
