TRIBE IIL-PTERIDE^. 
IV. CHEILANTHES, Swartz. Lip -Fern. 
Fruit-dots not very evident. Involucre almost always broken up by 
the cuts or lobes on the final divisions, often with a whitish papery pro- 
longation. Final divisions very minute or small. Bi- to quadri-pinnate 
ferns. {See Notholcena for three exceptional species.') 
Sixty species in the United States. Growing in the clefts of rocks. Some species 
approach Notholsena very closely, but the margin is always slightly recurved, at least. 
Greek lip -flower, from the shape of the indusium. 
* Involucres situated between the teeth of the final divisions. 
21. C. Califorilica, Mettenius. (The Californian C.) 
Fronds quadri-pinnate, very broadly ovate, smooth; all the rachises 
but the primary one winged ; lower pinnae more developed on the lower 
side; final divisions lanceolate, cut or toothed, very acute, teeth often 
recurved; involucres crescent-shaped, thin and papery. {Hypolepis , 
Hooker.) 
Damp and shady canyons along the coast; Santa Cruz, California to Sonora, Mexico. 
** Involucres not situated between the teeth of the final divisions, extend- 
ing over the tips of several veinlets, but not in an unbroken line all around 
the final divisions. 
-K- Frond not glandular, usually smooth. 
-5-i- Frond bright green, pinnate ; pinnce tivice-parted, but not divided. 
22. c. Wriglltii, Flooker. ( Wright's C.) 
Fronds ovate-oblong; pinnae about five pairs, deltoid, distant. Stalk

Arizona, New Mexico and Texas. 
Fronds bi- or tri-pinnate. Texture firm. 6 to 12 inches high. 
23. C. niicropliylla, Swartz. (The small leaved C.) 
Frond often tri-pinnate, smooth or slightly pubescent, broadly lan- 
ceolate ; lowest pair of pinnae the largest ; final divisions deeply cut : stalks 
dark-brown, rusty-pubescent on the upper side: involucre of the same 
color as the frond. 
Florida, Arkansas and New Mexico; south to Chili; common in the West Indies. 
24. C. Alabamensis, Kunze. (The Alabama C.) 
Frond bi-pinnate, narrowly lanceolate, nearly smooth; lowest pair of 
pinnae not larger than those next above ; final divisions with a little lobe 
on one side, or, in larger specimens, with several lobes or teeth : stalks 
black, smooth, woolly at base: involucre light colored, papery. Closely 
resembles No. 23. {Fte?ds , Buckley; Pellcea , Baker.)
