Kentucky, and Alabama, and westward to Arizona.

(2) HAIRY LIP FERN. _Cheilánthes lanòsa, C. véstita_

[Illustration: Hairy Lip Fern]

Fronds twice pinnate, lanceolate with oblong, pinnátifid pinnules; seven
to fifteen inches tall, slender and rough with rusty, jointed hairs. Pinnæ
triangular-ovate, usually distant, the ends of the rounded lobes reflexed
and forming separate involucres which are pushed back by the ripening
sporangia.

This species like the other lip ferns is fond of rocks, springing from
clefts and ledges. While hairy it is much less tomentose than the two
following species. Unlike most of the rock-loving ferns this species is not
partial to limestone, but grows on other rocks as well. It has been found
as far north as New Haven, Conn., also near New York, and in New Jersey,
Georgia, and westward to Wyoming and southward.

(3) WOOLLY LIP FERN. _Cheilánthes tomentòsa_

Fronds eight to eighteen inches long, lanceolate-oblong, tripinnate. Pinnæ
and pinnules ovate-oblong, densely woolly especially beneath, with slender,
whitish, obscurely jointed hairs. Of the ultimate segments the terminal
one is twice as long as the others. Pinnules distant, the reflexed, narrow
margin forming a continuous, membranous indusium. Stipe stout, dark brown,
densely woolly.

By donning its thick coat of wool this species is prepared to grow in
the most exposed situations of the arid southwest. It is said to be the
