pinnatifid or entire segments, the lower ones often distinct; 
rachises furrowed, scabrous, densely paleaceous throughout 
with deciduous chaff intermixed with minute appressed per- 
sistent dark scales; texture herbaceous, surfaces naked, or 
minutely pilose above along the veins, veinlets simple, or in 
immature segments appearing forked: sori medial, indusia 
fugacious, disappearing early. 6132, shaded banks of cafion 
near Orizaba, 4,500", Feb. 6, 1895. 
magnificent fern about which I do not even yet feel pos- 
itive; but as I have been unable to place it satisfactorily, and 
as my good friend Prof. Underwood thinks it new, I hazard 
its publication. It seems strange, however, as Mr. Pringle 
remarks, that a fern of its proportions should have escaped 
the attention of other collectors who have collected in the 
vicinity of Orizaba. 
It comes very near Mr. Baker’s Mephrodium intermedium, 
some specimens of which at Cambridge closely resemble the 
smaller specimens of Mr. Pringle’s plant. 
The following synonyms may serve for those who prefer 
other generic names: Nephrodium scabriusculum; Dryopteris 
scabriuscula; Lastrea scabriuscula. 
Aspidium strigilosum, n. sp. 
Rootstock short, sub-erect, roots densely clothed with light 
rown wool, caudex and base of stipes clothed with long 
dark brown fibrils: stipes tufted, 4 to 7" long, strongly chan- 
neled, light brown, gray when young, scabrous to the touch 
and fibrillose: lamine lanceolate, 8 to 11'* long, 2.5 to 4 
broad at base, narrowing gradually to the acute apex, pal 
tially bipinnate below, above pinnate, the apex deeply sae 
natifid to the tip; pinne stalked (uppermost subsessile of 
sessile), alternate (lower ones sometimes opposite), distant 
lanceolate (reproducing the laminz in outline), 1.5 to 2” long 
to §" broad at base; divisions oblong or sub-falcate, I* 
point; texture herbaceous, both surfaces finely and g/4% 
losely pubescent, the margins minutely ciliated; iene 
throughout strigose and fibrillose; veins simple, sori com 
the costa, 3 to § or 6 pairs to a pinnule; indusia fugacint
