Rhizome creeping, thickly clothed with long turgid mainly light- or yellowish-brown 
hairs; fronds several, dorsal, distichous, loosely fasciculate, the stipes of the fertile fronds 
not equaling the sterile fronds. Fertile fronds 10-50 cm. long, rigidly erect; stipe up to 
30 cm. long, usually longer than the sterile lamina, mostly stoutish, dull-stramineous or 
light-brownish from a darker base, nearly terete or lightly canaliculate above, at first 
noticeably dark-fibrillose especially toward the base, glabrescent; sterile lamina broadly 
deltoid-ovate, up to 18 cm. long and 15 cm. broad, long-acuminate, once-pinnate, the rachis 
similar to the stipe, sulcate, deciduously fibrillose; pinnae 1-4 pairs, approximate or the 
lower ones slightly apart, spreading or somewhat ascending, equilateral or nearly so, peti- 
olate, the 2 lower pairs about equal, oblong-lanceolate from an obtusely cuneate or rounded- 
truncate base, in large specimens 6.5-9.5 cm. long and 2-2.5 cm. broad, tapering gradually 
from near the middle to a long acute apex; upper pinnae smaller and relatively broader, 
narrowly ovate-lanceolate, the terminal pinna similar but usually much larger (maxinium 
9-11.5 cm. long), deltoid-lanceolate, the apex greatly produced; leaf-tissue rigidly coria- 
ceous, thick, bright lustrous green above, paler and very sparingly glandular below, gla- 
brous upon both surfaces; veins oblique, repeatedly dichotomous, somewhat apart except 
toward the margin, distinctly impressed upon the upper surface, elevated below, glabrous; 
margins cartilaginous, usually serrulate, the teeth stoutish, appressed or commonly ham- 
ate; fertile pinnae up to 15 cm. long, usually much shorter, never equaling the sterile 
lamina, borne 1.5-3 cm. below, ascending, the panicle about twice as long as the slender 
stalk, flattish, lanceolate in outline, the divisions mostly close, oblique, the lower and mid- 
die ones distinctly stalked; spores widely and sharply striate. Sterile fronds considerably 
smaller, otherwise similar. 
TYPE LOCALITY: Western Mexico. 
' DISTRIBUTION: Southern and western Mexico to the Departments of Petén and Alta Verapaz, 
Guatemala; Cuba (rare). 
ILLUSTRATION: Hook. doc. cit. (small specimens). 
24. Anemia cuneata Kunze; Spreng. Syst. Veg. 4: 32. 1827; 
Linnaea 9: 21. 1834. 
Rhizome rather freely creeping, densely clothed with turgid acicular dark-brown hairs ; 
fronds several, dorsal, manifestly distichous, spaced, the stipes of the fertile fronds not 
equaling the sterile fronds. Sterile fronds 8-31 cm. long, rigidly ascending; stipes slender, 
up to 12 cm. long, shorter than the lamina, stramineous from a castaneous base, glabrous ; 
lamina up to 19 cm. long, usually much smaller, narrowly ovate-lanceolate in outline, 
attenuate, bipinnate or, as to the lower pinnae, tripinnate; pinnae 4-8 pairs, alternate, 
distant, strongly ascending, decreasing gradually from the base of the lamina toward the 
apex ; lower and middle pinnae petiolate, lanceolate in outline, acute or attenuate, with 
3-5 pairs of very oblique alternate narrow pinnules, of these the upper basal one largest, 
pinnate at the base and comprising 3-5 alternate slender long-cuneate narrowly oblanceo- 
late or nearly linear segments, these strongly fimbriate or inciso-dentate at the apex; 
upper pinnae gradually simpler, at least bipinnate, only the uppermost simple, finally con- 
fluent at the slender serrate apex; pinnules and segments anadromous; veins evident 
above, scarcely so below ;. leaf-tissue rigidly herbaceous, slightly lustrous, paler and glandu- 
lar below, and with a very few scattering stiff hairs between the veins upon both surfaces. 
Fertile fronds more rigidly erect, up to 30 cm. long; stipe as long as the lamina or com- 
monly twice as long; sterile lamina similar to that of the sterile frond; fertile (basal) 
pinnae remote, long-petiolate, elongate but not equaling the sterile lamina, the divisions 
short and remote, the lower ones stalked, with several pairs of close simple or forked seg- 
ments; spores flexuose-striate, the ridges slightly undulate.
