606 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 
ones mostly oblong, narrower, and closer; segments 4 or 5 pairs, mostly ap- 
proximate, oblong, subfalcate, obtuse, only the basal ones of the larger pinnse 
sessile or subsessile, these 3 to 4.5 mm. long, strongly crenate, the other seg- 
ments entire or sometimes lightly crenate; sori marginal, strongly confluent 
at maturity in a relatively broad line, covering the concave leaf surface between 
the midvein and the slightly revolute but unmodified margin, partially con- 
cealed by scales. 
Type in the U. 8. National Herbarium, no. 50929, collected in low mountains 
about 25 miles southwest of Monclova, State of Coahuila, Mexico, September 
9 to 19, 1880, by Dr. Edward Palmer (no. 1889). Additional specimens of the 
same collection are mounted on sheet no. 834644. 
Related to Notholaena grayi Davenp., with which it was confused by Eaton, 
but readily distinguished from that species in having its upper leaf surfaces 
distinctly villous from the presence of numerous lax, whitish, tortuous hairs, 
Notholaena grayi being sparsely pulverulo-ceraceous above and devoid of any 
hairy covering whatever. The rhizome scales also are smaller and much more 
strongly ciliate.

Notholaena hyalina Maxon, Amer. Fern Journ. 5: 4. 1915. 
The above synonymy will indicate an error, pointed out by Mr. Carl Christen- 
sen in a recent letter, into which both Christ and the writer have fallen in 
describing independently, as a segregate of Notholaena aschenborniana, the 
plant of southern Mexico long ago described by Fée as Notholaena galeottii. 
Fée’s type (Caputalpan, Oaxaca, alt. 3,000 meters, Galeotti 6565) has not been 
seen by the writer; but the description, so far as it goes, seems to apply to 
N. hyalina. Christ’s description of Puebla specimens as N. ersenii was, un- 
fortunately, overlooked by the writer until the article describing N. hyalina 
was in type. The inaccurate and misleading phrase “pinnis .... pagina 
superiore laevigatis ” left some doubt that the plants described by the writer as 
having the upper surfaces “ conspicuously hispid by numerous spreading hyaline 
simple hairs” could really be the same, although the general agreement of the 
descriptions was recognized at that time. Christensen has since examined 
Arséne’s specimens and associates them with Pringle 3297, the type of NW.

In addition to the specimens of N. galeottii previously listed by the writer 
(as N. hyalina) the following are now at hand:

The more northerly range of N. aschenborniana Klotzsch (N. bipinnata 
Liebm.) has been indicated elsewhere,’ with citation of specimens.
