segments usually remote; spores broadly striate, not echinulate. Sterile fronds with stout- 
ish stipes, spreading; lamina oblong, 3.5-7 cm. long, 1.5-3 cm. broad; pinnae 5-13 pairs, 
spreading, similar to those of the sterile lamina of the fertile frond. 
TYPE LOCALITY: Panama. 
DISTRIBUTION: Panama; also in Colombia and Brazil.

5. Anemia obovata (Underw.) Maxon, sp. nov. 
Ornithopteris obovata Underwood, MS. 
Rhizome decumbent, relatively stout; fronds cespitose, the stipes of the fertile fronds 
scarcely or considerably surpassing the sterile fronds. Fértile fronds (including the fertile 
pinnae) 8-21 cm. long; stipe 5-13 cm. long, very slender, deeply sulcate, rusty-pilose, 
stramineous throughout or darker at the base ; lamina ovate or oblong-ovate, 3-6 cm. long, 
2.5-4.2 cm. broad, obtuse, once-pinnate, the rachis slight, rusty-pilose or glabrate ; pinnae 
2-4 pairs, opposite, approximate, spreading, the lowermost sessile, elliptic-oblong, unequally 
cuneate, those above narrower, subsessile, symmetrical, the uppermost narrowly obovate 
and semiadnate, the terminal segment much longer, obovate, cuneate, simple or deeply 
bilobed ; margins thickened, unequally denticulate-crenulate, not lobed; leaf-tissue mem- 
branous, opaque, dull-greenish above, glabrate or very sparingly pilose above, below gla- 
brous and minutely glandular; veins elevated above, scarcely so below; fertile pinnae 
3.5-8.5 cm. long, easily surpassing the sterile lamina, the closely branched panicle shorter 
that the slender stalk ; spores broadly striate, echinulate. Sterile fronds 5-10 cm. long, 
the lamina as long as the stipe, similar to that of the fertile frond. 
Type collected in Cuba, 1865, Wright 3933 in part (herb. N. Y. Bot. Gard.), the other portion 
of the number being A. pastinacaria Moritz. 
DISTRIBUTION : Known only from the type number.

Pens hirtum Presl, Abh. BOhm. Ges. Wiss. V. 4: 352, in part. 1845. 
Rhizome ascending, stoutish; fronds 3-6, fasciculate, mostly fertile, the stipe of the 
fertile fronds scarcely exceeding the sterile fronds. Fertile fronds 20-35 cm. long; stipe 
13-21 cm. long, stoutish, dull-stramineous, canaliculate, densely rusty-villous; lamina del- 
toid to broadly ovate-deltoid, 8-15 cm. long, 6-11 cm. broad, once-pinnate, acute, the 
rachis subflexuous, clothed like the stipe; pinnae 6-13 pairs, approximate or contiguous, 
spreading, the lowermost the largest, sometimes deflexed, short-petiolate, strongly inequi- 
lateral at the base, widely exciso-cuneate below, truncate and rounded above, obliquely 
lanceolate, broadest above the middle (up to 2 cm.), acute, the margin minutely and irregu- 
larly crenulate, slightly thickened; succeeding pinnae gradually smaller, short-petiolate, 
only the uppermost narrowly adnate, oblong-spatulate, finally confluent at the acuminate 
or subcaudate apex; leaf-tissue membrano-papyraceous, dull-greenish, paler below; veins 
prominent above, subimmersed below, pilose upon both surfaces but especially above; fer- 
tile pinnae 8-17 cm. long, slightly surpassing the sterile lamina, the stalks about one-half 
longer than the close panicle, pilose; spores striate-cristate, echinulate. Sterile fronds 
few, similar to the fertile, the lamina slightly larger. 
TYPE LOCALITY: Near Leogane, Haiti. 
DISTRIBUTION: Haiti, Porto Rico, St. Kitts, Guadeloupe, and Martinique; also in South 
America? 
ILLUSTRATION: Plumier, Traité Foug. p/. 157. 
Note.—The Porto Rican specimens average about one-half smaller than the measurements 
given in the description.
