beneath with ovate reticulated ciliate scales, pinnatifid into rather 
few oblong or oblong-spatulate entire segments separa<ed by broad 
rounded sinuses ; veinlets anastomosing in a single series of large 
areoles, each areole enclosing a- sorus, outer veinlets free. — Baker, 
Syn. Fil., ed. 2, p. 512. 
Collected on the Huachuca Mts., Arizona, by Prof, and Mrs. 
Lenimon in August, 1882. 
This is a well-known Mexican fern of the same group with P. 
incanum, from which it differs by its usually larger size, its fewer, 
broader and more distant segments, and especially by the heavier 
covering of larger, laxer and beautifully ciliated scales; It is No. 971 
of Parry and Palmer's collection of 1878, from San Luis Potosi, and 
No. 210 of Ghiesbreght's Chiapas distribution. 
■ 44, NoTHOL^NA Californica, h. sp. — Rootstock short ; stalks 
clustered, two to four inches long, black, wiry, when young scaly with 
lanceolate dark-brown rigid scales ; frond one to two inches long, 
broadly deltoid-ovate or pentagonal-ovate, from a quadri-pinnatifid 
base gradually simpler to the apex; ultimate segments oblong or 
triangular-oblong, small (1-2 lines long) and very numerous and 
crowded ; upper surface minutely glandular ; lower surface copiously 
farinose with yellow or whitish powder, except on the strong black- 
ened rachis and midribs ; margins more or less recurved, but not 
covering the copious dark-brown sporangia.

This plant I have for a long time confused with N. Candida, 
Hook., as at pp. 22 and 23 of the second volume of Ferns of North 
America, where it is spoken of as the Californian form of that 
species. It has smaller and more compound fronds than C. Candida, 
and occupies in the genus a position about midway between that 
species and iV. Chilensis, The powder is so abundant that it is some- 
times difficult to glue a specimen to paper,

ing ; stalks clustered, dark-chestnut, copiously beset at the base 
with rigid blackish ciliated lanceolate-acuminate scales, which be- 
come niore delicate higher up the stalk, and pass into a dense whitish 
or pale-ferruginous tomentose mass which covers the frond ; fronds 
4-10 inches long, pinnate, the pinnae an inch long or less, rarely 
more, pinnatifid into very numerous sessile, oblong, entire or crenately 
lobed obtuse segments, upper surface at length becoming smoothish, 
the lower indistinctly farinose beneath the heavy coating of ciliately 
cleft scales; sporangia forming a dark line around the edges of the 
segments. — Klotzsch, in Z/;/;/^^, xx., p. 417. 
This was first gathered near Chepultepec, in Mexico, by Alwm 
Aschenborn. Fournier (PL Mex., Crypt., p. 124) gives among the

Edward Palmer found it in the mountains east of Saltillo, Nuevo 
Leon, Mexico, in 18S0 ; and now it is found and identified by Mr, 
Davenport among some unnamed ferns sent by Prof- Lemmon from 
the Huachuca Mts. It has a decidedly less compound frond than 
J^, Neivberryi^ and may be easily recognized by the beautikilly
