38 NORTH AMERICAN FLORA [VorumE 16 
Rhizome ascending or horizontal, closely covered with yellowish-brown hairs; fronds 
several, fasciculate, 25~70 cm. long, rigidly erect; stipes stoutish, obtusely angled, sulcate 
and brownish in the lower part, lighter and marginate above ; lamina abruptly expanded, 
broadly obdeltoid or suborbicular in outline, 10-20 cm. long, 15-30 cm. broad, 2-6 times 
dichotomously cleft or incised, the divisions variable, linear-oblong or linear to narrowly 
obdeltoid, pluricostate, the apices deeply and usually irregularly fimbriate-dentate or 
sharply lacerate by the production of the prominent costae; sporangiophores numerous, 
terminal upon many of the elongate costae, recurved, conduplicate or with age diffuse, 6-10 
mm. long; fertile segments 10-15 pairs, slender, the lower ones 2.5-5 mm. long, the upper 
ones gradually shorter, obtuse, conspicuously pilose upon the costa and margins; spores 
delicately and minutely verrucose. 
TYPE LOCALITY: Trinidad. 
DISTRIBUTION : Southern Mexico and Central America; Jamaica; Santo Domingo (rare); also 
in South America.

Schizaea fluminensis Miers; Sturm, in Mart. Fl. Bras. 12: 184. 1859. 
Rhizome slender, horizontal, densely rusty-pilose ; fronds 1-3, erect or ascending, 4— 
30 cm. long; stipe 3-24 cm. long, the lower portion to a distance of 3-15 cm. usually 
brownish and tortuous from being buried in humus, the upper portion flattish, slender, 
stramineous, at the summit greenish-marginate, passing gradually into the lamina, spar- 
ingly pilose; lamina narrowly obdeltoid in outline, narrowly cuneate, 2~7.5 cm. long, 1.5- 
4 cm. broad, 2 or 3 times dichotomous (rarely simple), the segments obliquely ascending, 
1-3 mm. broad, unicostate or, if bicostate, cleft at the summit, each costa produced and 
developing a sporangiophore; sporangiophores 6-15 mm. long, incurved, conduplicate ; 
fertile segments 7-14 pairs, slender, linear, pilose along the costae and margins, the lower 
and middle ones about equal, the upper ones shorter; spores delicately verrucose. 
TYPE LOCALITY: Near Panuré, by the Rio Uaupés, Brazil.

Rhizome relatively stout, short-creeping, densely clothed with lustrous castaneous 
hairs ; fronds fasciculate, erect, the fertile ones usually far surpassing the sterile. Sterile 
fronds erect, 15-30 cm. long; stipes pilose, dull-stramineous from a darkish base, concave- 
marginate along the anterior face, convex below; lamina orbicular (the divisions spread- 
ing), 10-12 cm. broad, in drying conduplicate and broadly obdeltoid, 5-8 times dichoto- 
mous, the ultimate divisions linear, 1-2 mm. broad, acutish, unicostate, the costa elevated 
above, scarcely so below, the margins thickened and conspicuously scabrous at the upper 
surface. Fertile fronds stouter, 30-50 cm. long, 3 or 4 times dichotomous, the ultimate 
divisions slender; sporangiophores strongly incurved (straight at first), 1.5-2 cm. long, 
conduplicate, the segments (15-25 pairs) slender, the middle ones distinctly the longest, 
the margins and costae pilose; spores delicately and very minutely verrucose. 
TYPE LOCALITY: Ventanilla de ‘Cassapillo, Peru. 
DISTRIBUTION: Eastern Cuba; also from Costa Rica to Peru and British Guiana.
