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. 
Chetlanthes 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 /anosa 
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 Cheztlanthes. Some will consider them 
fully as difficult as the wood ferns. Chetlanthes tomentosa, 
however, is one that need not be mistaken. It has a 
general resemblance to C. vestita, but is taller, woollier
