MAXON—STUDIES OF TROPICAL AMERICAN FERNS. 605 . 
ceraceous covering; margins slightly revolute, concealed at maturity by the con- 
tinuous but narrow line of very dark brown sporangia. 
The following specimens of N. schaffneri are in the National Herbarium: 
Texas: Limpia Canyon, Presidio County, Nealley 894 (560), the type of 
N. nealleyi, Goodenough Spring (near Comstock), Valverde County, 
October, 1892, Nealley 123 (3 sheets). 
JALisco: Dry shaded ledges, barranca near Guadalajara, alt. 1,500 meters, 
Pringle 1864 (2 sheets) ; Pringle 3880 (2 sheets) ; Pringle 11789. Face 
of large rocks in a canyon at Rio Blanco, September 19, 1886, Palmer 
555 (2 sheets). Bolafios, Rose 2910. 
ZACATECAS: Near Monte Escobedo, Rose 2662. 
PuEBLA: Tlacuilotepec, July, 1909, Purpus 4029 (ex Mus. Bot. Berol.). 
VERACRUZ: Barranca de Santa Maria, Zacuapan, October, 1912, Purpus 6199. 
Of these specimens, Pringle’s 1864 was distributed as N. grayi Davenp., and 
Palmer’s 555 was so referred by Eaton.’ Notholaena schaffneri is not very 
closely related to that species, however, differing widely in its black, rigidly 
long-ciliate rhizome scales and its strongly barbate-paleaceous rachises and 
midveins, characters described above. The differences in leaf cut and in gen- 
eral appearance are equally pronounced, Notholaena grayi having the fronds, 
rachises, and midveins clothed with numerous lax, tortuous, pale brown, de- 
ciduous scales wholly different in color, form, structure, and direction from 
those of NV. schaffneri. 
The characters and distribution of N. grayi were discussed briefly by the 
writer ® some time ago with reference to the strict form of this species de- 
scribed, under the invalid name Notholaena hypoleuca Goodding,* upon speci- 
mens collected from Slavonian Canyon, Mule Mountains, Arizona, August, 1911, 
by Leslie N. Goodding (no. 1004); U. S. Nat. Herb. no. 692687. Of the United 
States specimens mentioned those collected in Arizona by Lemmon and by G. R. 
Vasey are the best developed, agreeing closely with Faxon’s beautiful illustra- 
tion of the type. 
In studying Notholaena grayi the following new species was detected: 
Notholaena aliena Maxon, sp. nov. 
Plants small, 6 to 13 cm. high, the several fronds slender, long-stipitate, 
fasciculate. Rhizome (incomplete) small, presumably multicipital, the branches 
apparently very short, horizontal, thick, densely paleaceous, the scales appressed, 
1.5 to 2 mm. long, linear-deltoid, stiff, very dark brown, opaque, conspicuously 
long-ciliate, the cilia stout, brown, unicellular, curved, irregularly divergent, 
either antrorsely or retrorsely directed, fragile; stipes 3 to 7 cm. long, about 
0.4 mm. in diameter, arcuate, light brown from a darker base, here deciduously 
paleaceous, the scales nearly capillary; lamina linear to linear-oblong, 4 to 8.5 
cm. long, 1 to 1.5 cm. broad, acutish, subbipinnate in the basal part, very deeply 
bipinnatifid nearly throughout, the pinns minutely glandular-ceraceous above 
end laxly villous with tortuous white hairs, densely yellowish ceraceous be- 
neath, this covering mostly concealed at maturity by numerous pale-brown 
capillary scales arising from the secondary rachises and the midveins of the 
segments; pinne 8 to 13 pairs, subopposite to alternate, slightly ascending, the 
lower and middle ones deltoid to deltoid-ovate, acutish, distant, the upper
