CHEILANTHES AND MAIDENHAIR. 239 



and the secondary oblong and deeply lobed. Both 

 sides are invested with long whitish hairs which are 

 most abundant upon the under surface. The fronds are 

 dark grayish-green, and the stipe and rachis are dark 

 chestnut-brown and covered with tiny hairlike scales. 



The sori are very small and are borne on the lobes of 

 the pinnules whose tips roll over them in little pocket- 

 like indusia. These are always green and have faint 

 likeness to the indusia of other ferns. In old fronds the 

 confluent sori push out from the indusia and cover a 

 large part of the pinnules. In the Key to the Genera, 

 a fruiting pinnule of this species is shown. 



Cheilanthes vestita is found southward to Georgia and 

 Texas, and westward to Kansas. It is probably not an 

 abundant species in any locality but where there are ex- 

 posed cliffs of igneous rock there is always the possibility 

 of finding it. The name of hairy lip-fern, by which this 

 species is frequently mentioned in the books, is rarely 

 used in speaking of it. Recently the specific name lanosa 

 has been given this species. Both names have reference 

 to the hairy fronds, and all that has been gained by the 

 change is the addition of another scientific name to per- 

 plex the beginner and the satisfying of certain demands 

 for priority. Our illustration is from specimens col- 

 lected by the author at Milburn, N. J. 



Cheilanthes Tomentosa. 



It is usually difficult for the young collector to identify 

 the species of Cheilanthes. Some will consider them 

 fully as difficult as the wood ferns. Cheilanthes tomentosa, 

 however, is one that need not be mistaken. It has a 

 general resemblance to C. vestita, but is taller, woollier
