604 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
LoweErR CALIFORNIA: San Telmo, April 17, 1886, Orcutt 1461. Los Angeles 
Bay, Gulf of California, 1887, Palmer 552. Ensenada, January 235,

Cedros Island, March 18 to 20, 1889, Palmer 748. 
The known ranges of the three species just discussed are entirely natural. 
Notholaena cretacea is apparently confined to the southerly region of Puebla; 
N. neglecta is found chiefly in the northern parts of Mexico, barely entering 
the United States in extreme southeastern Arizona; N. californica occupies the 
region of California and Lower California, the single Arizona station being close 
to the southern California localities and of very similar character, and remote 
from the Arizona localities for N. neglecta.

Although Notholaena schaffneri is not at all of close relationship to any of 
the foregoing species, specimens of N. neglecta have nevertheless been so 
named and distributed in at least one instance (Sierra Mojada, Jones). On 
this account and also because the excellent distinctive characters of N. schaff- 
neri have been very generaily overlooked, it seems desirable to include a re- 
description of this species. A considerable amount of variation in the glandular- 
ceraceous covering is observed, some of the specimens (notably Seaton 894 
(560) and Palmer 555) having the fronds rather densely covered beneath 
with separate translucent glands and nearly or quite lacking the usual thick, 
continuous coating of whitish powder. Pringle’s 1864, however, embraces speci- 
ments of both types. These differences, which are apparently not wholly due 
to age, are similar to those mentioned under NV. californica, above, 
Plants 10 to 35 cm. high, with numerous stiflfish fasciculate fronds, their 
vascular parts freely barbate-paleaceous. Rhizome multicipital, the divisions 
several, stout, aggregated, decumbent or ascending, densely covered with 
closely impacted seales, these 2.5 to 3.5 mm. long, very slender, long-attenuate 
and subulate from a slightly broader base, coal-black and opaque (except for a 
short yellowish brown median stripe at the extreme base), rigid, evenly long- 
ciliate throughout, the cilia 0.09 to 0.15 mim, long, blackish, rigid, mostly 
straight, divergent, 15 to 25 on each side; stipes straight or nearly so, 2.5 
to 10 cm. long, about 1 mm. in diameter, dark brown to blackish, closely 
glandular, often deciduously whitish-furinose, bearing numerous rigidly diver- 
gent ciliate scales similar to those of the rhizome but reddish brown in color; 
lamina linear-oblong to linear-oblanceolate, T to 20 cm. long, 2 to 5.5 cm. broad, 
acuminate, gradually narrowed toward the base, at least bipinnate throughout, 
the largest fronds subtripinnate; rachises and the midveins of the segments 
beneath bearing humerous long spreading subulate scales, these only 1 or 2 
cells broad, appearing like stiff turgid jointed hairs; pinne 15 to 25 pairs below 
the acuminate apex, subopposite to alternate, the lower ones gradually re- 
duced, deltoid, 7 to 15 mm. long, subdistant, those above gradually longer, 
larger, and closer, mostly 1.5 to 3 cm. long, deltoid-ovate to narrowly oblong, 
slightly inequilateral, acutish, with about 5 to 9 pairs of subdistant to approxi- 
mate narrowly oblong segments below the lobate apex; segments sessile and 
pinnatisect, or mostly semiadnate and pinnately lobed, the lobes (3 or 4 pairs) 
rounded, adnate, suborbicular, obscurely crenate, or the smaller ones entire; 
leaf tissue rigidly herbaceous, sparsely but evenly glandular or delicately 
whitish-ceraceous above, densely so beneath, usually developing a thick white
