Part 1, 1909] SCHIZAEACEAE 41 
shorter, more narrowly cuneate, essentially equilateral, lanceolate, the uppermost 2 or 3 
usually confluent, forming a deeply lobed or parted acuminate terminal segment; leaf-tissue 
papyraceo-membranous, livid-green and lustrous above, a little paler below, pellucid, 
minutely glandular below, rusty pilose-scabrous upon both surfaces, mainly along the veins 
and nearly median midvein; veins elevated above, apparent below, close, very oblique, 
repeatedly dichotomous, mostly free, casually connivent; margins unevenly crenulate- 
undulate, slightly thickened; fertile pinnae 14-18 cm. long, equaling or slightly exceeding 
the sterile lamina, the panicle nearly as long as the slender rusty-pilose stalk, the divisions 
short, the basal ones distant; spores striate, echinulate. Sterile fronds shorter than the 
fertile, otherwise similar, the lamina and the stipe about equal in length. 
Type collected near Castleton, Jamaica, altitude about 150 meters, April, 1903, Underwood 1971 
(herb. N. Y. Bot. Gard.). 
DISTRIBUTION: Jamaica, Cuba, and Haiti, common, from near sea level up to 900 meters or 
more.

Rhizome ascending or decumbent, stout; fronds closely fasciculate, the stipes of the 
fertile fronds usually much shorter than the sterile fronds. Fertile fronds (including the 
greatly elongate fertile pinnae) 10-30 cm. long; stipe 1-7 cm. long, stramineous, strongly 
arcuate at the base, sparsely villous above, finally glabrate; sterile lamina obovate-oblong 
to obovate or rarely oblong, 1-7 cm. long, 1-3 cm. broad, obtuse, once-pinnate, the rachis 
similar to the stipe; pinnae 2-9 pairs, spreading or the lower ones slightly deflexed and 
the upper a little ascending, the terminal usually larger than those next below, broadly 
rotund or deltoid from a cuneate base; middle pinnae contiguous or subimbricate, trape- 
zoid-oblong, inequilateral, cuneate at the base below, rounded-truncate at the base above 
and close to the rachis; basal pinnae shorter, rounded-ovate from a cordate base; leaf- 
tissue rigidly membrano-coriaceous, usually lustrous above, opaque and paler below, con- 
spicuously pilose and sparsely glandular upon both surfaces, often scabrous above from the 
tuberculate bases of the stiffish antrorse yellowish-white hairs; margins thickish, crenu- 
late; fertile pinnae greatly elongate, 9-23 cm. long, far surpassing the sterile lamina, the 
stalk slender, 3-5 times as long as the panicle, stramineous, sparsely villous or glabrate, the 
panicle usually dense, the inferior segments often remote; spores narrowly striate, echinu- 
late toward the angles. Sterile fronds rosulate, very short-stipitate; lamina 2-9 cm. long, 
1-3.5 cm. broad, narrowly obovate or obovate-oblong; pinnae 2-9 pairs, close, the lower 
ones much reduced and broadly cuneate. 
TYPE LOCALITY: Island of Taboga, Panama. 
DISTRIBUTION : Mexico and Central America to Colombia, Venezuela, and Brazil.

Osmunda oblongifolia Cav. Ic. 6: 69. 1801. 
Rhizome oblique; fronds fasciculate, the stipes of the fertile fronds mostly surpassing 
the sterile fronds. Fertile fronds (including the elongate fertile pinnae) 9-30 cm. long ; 
stipe 5-13 cm. long, stoutish, sulcate, dark-stramineous, sparsely villous, glabrate; sterile 
lamina oblong, obtuse, 4-7 cm. long, 1.5-2.8 cm. broad, once-piunate, the rachis similar to 
the stipe; pinnae 6-12 pairs, contiguous or apart, spreading, sessile, the middle ones trape- 
zoid-oblong, obtuse, narrowly rounded-cuneate below, rounded-truncate above and con- 
tiguous to the rachis, the lower ones similar but a little shorter, inequilateral, exciso-cune- 
ate below, the terminal pinna as large as those next below (or larger), cuneate, the outer 
portion rotund or sharply truncate ; leaf-tissue coriaceous, lustrous above, opaque and paler 
below, more or less pilose, sparsely glandular below; margins thickened, repand, sub- 
entire or undulate ; fertile pinnae elongate, 12-20 cm. long, far exceeding the sterile lamina, 
the stalks slender or stoutish, 3-4 times as long as the panicle, the panicle dense, the lower
