WOOTON AND STANDLEY—FLORA OF NEW MEXICO. 21 
Reported from the following localities: Las Lagunitas near Las Vegas, 7. S. Bran- 
degee; San Domingo, Bigelow; Sandia Mountains, Ferris. 
5. Notholaena fendleri Kunze, Farmkr. 2: 87. pl. 136. 1851. 
Type Locauity: “In New Mexico.” Type collected by Fendler. 
Rance: Wyoming to New Mexico and Arizona, and in northern Mexico. 
New Mexico: Santa Dona; Socorro; Cross L Ranch. Dry hills, in the Upper 
Sonoran Zone. 
The type is Fendler’s 1017a, collected in 1847 near Santa Fe. Although named from 
New Mexico, the species is very rare in the State, ranging mainly farther north. 
3. ADIANTUM L. Marmpen-HAIR FERN. 
Sori marginal, short, covered by a flaplike reflexed portion of the edge of the pin- 
nule, on the free but approximate tips of forking veins; fronds bipinnate; stipes slen- 
der, black, wiry; pinnules mostly obovate-cuneate, with a few incised teeth. 
1. Adiantum capillus-veneris L. Sp. Pl. 1096. 1753. VENUS-HAIR FERN. 
Adiantum modestum Underw. Bull. Torrey Club 28: 46. 1901. 
Tyre Locauity: ‘‘ Habitat in Europa australi.’’ 
Rance: Virginia and Florida, westward across the continent except in the extreme 
northwest. 
New Mexico: Eight miles northwest of Reserve; East Fork of the Gila; San 
Andreas Mountains; Kingston; South Spring River. Damp cliffs, in the Upper 
Sonoran and Transition zones. 
The type of Adiantum modestum is Earle’s 261 from South Spring River. If dif- 
fers slightly from our other specimens in having broader, more rounded segments. 
When one examines a large series of specimens of A. capillus-veneris it is seen that it 
is a variable species and that A. modestum is hardly more than a local variation. 
4, PTERIDIUM Scop. Bracken. 
This is a coarse fern of almost world-wide distribution that occurs in the mountains 
of this State in parklike openings and beside small streams where the soil is rich 
and water plentiful. It is ordinarily not over 60 cm. high, but sometimes reaches 
a height of 2 meters. We have only one representative of the genus, the western or 
pubescent form. 
1. Pteridium aquilinum pubescens Underw. Native Ferns ed. 6. 91. 1900. 
TypE Loca.ity: ‘‘Utah, California, and northward.” 
RANGE: Western North America from New Mexico to British Columbia. 
New Mexico: Tunitcha Mountains; Chama; Santa Fe and Las Vegas mountains; 
Sandia Mountains; Mogollon Mountains; White Mountains. Open slopes, in the 
Transition and Canadian zones. 
5. CHEILANTHES Swartz. Lire Fern. 
Sori terminal or nearly so on all the veins, at first very small and rounded, later 
confluent; indusium consisting of the reflexed margins of the pinnules, in ours (except 
one species) continuous all around the pinnule. 
With the exception of C. wrightii our species belong to that division of the genus 
having very minute, beadlike segments with the whole margin reflexed. They grow 
in crevices of rocks and on ledges of cliffs in the mountains, generally between eleva- 
tions of 1,450 and 2,100 meters.
