46 NORTH AMERICAN ‘FLORA [VoruME 16 
petiolate, obliquely pinnatifid close to the costa into about 5-7 pairs of acute serrate or pin- 
nately incised segments; succeeding pinnules sessile to narrowly or broadly adnate, finally 
‘ confluent, lanceolate, acute, all sharply and obliquely pinnatisect; upper pinnae gradually 
simpler, sessile, only the uppermost adnate, the divisions all oblique; leaf-tissue herbace- 
ous, bright lustrous green above, paler below, pilose and glandular upon both surfaces, 
conspicuously so below; margins thickened, usually revolute or recurved; veins evident 
upon both surfaces; fertile pinnae stout, rigidly erect, 8-20 cm. long, surpassing the sterile 
lamina, often greatly so, short-stalked, the branches elongate; spores striate, smooth or 
minutely echinulate, the angles not produced. Sterile fronds 10-30 cm. long; lamina usu- 
ally as long as the stipe, ovate or ovate-deltoid, or subpentagonal by the basiscopic devel- 
opment of the basal pinnae; pinnules mostly anadromous, only those of the upper pinnae 
catadromous. 
TYPE LOCALITY: Brazil. 
DISTRIBUTION : Widely distributed in Mexico; also in Brazil, Paraguay, and Peru.

15. Anemia guatemalensis Maxon, sp. nov. 
Rhizome wanting; stipes of the fertile fronds mostly longer than the detached sterile 
fronds. Fertile fronds 30-45 cm. long; stipe stout, 23-30 cm. long, erect, yellowish, very 
densely clothed with swbpersistent spreading dark-rusty hairs ; sterile lamina deltoid, 12-16 
cm. long, 10-12 cm. broad, acute, tripinnate below, deeply tripinnatifid nearly throughout, 
the rachis conspicuously ferruginous-pilose ; pinnae about 10 pairs, spreading or ascending, 
contiguous or imbricate, short-petiolate, mostly ovate-lanceolate or the lowermost narrowly 
deltoid-ovate, these the largest, 6.5-7.5 cm. long, 2.5-3 cm. broad near the base, with 8 or 
9 pairs of oblong-lanceolate pinnules below the short subacute crenately lobed apex, the 
larger of these pinnate at the base, above deeply pinnatifid with about 4 pairs of segments, 
the basal ones crenately lobed ; upper pinnae gradually simpler, the pinnules short-stalked 
or sessile, only those of the uppermost pinnae finally adnate ; leaf-tissue rigidly chartaceo- 
membranous, thickish but translucent, dull-green above, lighter or yellowish-green below, 
obscurely glandular above, conspicuously so below, the upper surface glabrate, the lower 
conspicuously rusty-pilose along the secondary rachis, costae and veins; veins concealed or 
somewhat impressed above, scarcely evident below; margins slightly thickened; fertile 
pinnae stout, erect, 13-15 cm. long, nearly or quite as long as the sterile lamina, the stalk 
very short (2-2.5 em. long), the panicle with numerous strict erect branches, the lowermost 
of these up to 4.5cm. long with short pinnate divisions, the upper branches gradually 
shorter and closer, the uppermost densely crowded; spores striate, the angles not produced. 
Sterile fronds 16-33 cm. long ; stipe 8-9 cm. long; lamina 10-18 cm. long, 9-15 cm. broad, 
ovate-deltoid or subpentagonal, the basal pinnae strongly basiscopic, spreading, unequally 
deltoid, the inferior basal pinnules oblong-ovate, in the largest specimen 3.8 cm. long and 
1.9 cm. broad, with about 5 pairs of ovate-oblong pinnatifid or lobed segments below the 
trilobate apex, the lowermost sessile; pinnules mostly anadromous, only those of the upper 
third of the lamina catadromous.

16. Anemia Rosei Maxon, sp. nov. 
Rhizomes decumbent, stoutish, closely clustered ; fronds fasciculate, the stipes of the 
fertile fronds usually equaling or surpassing the sterile fronds. Fertile fronds 36-42 cm. 
long, weakly ascending; stipes rather slender, 19-26 cm. long, light-stramineous, arcuate 
or subflexuous, sparingly clothed with delicate very slender spreading fulvous hairs, these 
readily deciduous; sterile lamina deltoid-ovate, 14-16 cm. long, 9-12 cm. broad, acuminate, 
bipinnate or, as to the basal pinnae, nearly tripinnate, the rachis similar to the stipe, long- 
pilose; pinnae about 10-13 pairs, contiguous or the lower ones apart, these and the middle 
ones petiolate from a cordate base, broadly oblong-lanceolate, obtusish, slightly oblique, 
with 6-8 pairs of sessile or semiadnate deltoid-ovate, ovate or ovate-oblong oblique obtuse
