6. Danaea alata Smith, Mém. Acad. Turin 5: 420. 1793. 
A medium-sized plant; leaves dull, 35-70 cm. long, the stipes 10-25 cm. long, olive- 
brown or purplish with a coating of small scales, with 1-3 nodes, the upper of these some- 
times retaining small vestigial pinnae; sterile lamina elliptic, 27-45 cm. long, 13-22 cm. 
broad, the rachis olive or olive-brown, usually densely scaly, narrowly and discontinuously 
winged; pinnae 11-27, somewhat oblique, mostly straight, the middle ones oblong, 9-13 
em. long, 1.7-2.5 cm. broad, unequally and broadly cuneate to truncate or even cordate 
below, acuminate above, the margins entire, or sometimes more or less serrulate (the lower 
pinnae much reduced, broadly ovate to orbicular, 1-3 cm. long, the terminal pinna elliptic, 
longer); midveins densely scaly throughout, the veinlets scaly, mostly simple, 6-10 per 
em.; sporophyls narrower, with linear acute pinnae.

7. Danaea Fendleri Underw. Bull. Torrey Club 29: 673. 1902. 
Plant rather small; rhizome slender ; leaves 50-60 cm. long, the stipes 20-25 cm. long 
with 1-3 nodes, olive-brown, finely mottled, sparsely scaly, the scales small, blackish, 
appressed ; sterile lamina oblong, 30-35 cm. long, 12-16 cm. broad, the rachis olive, 
moderately scaly below, especially at the nodes, very narrowly winged ; pinnae mostly less 
than their own breadth apart, more distant below, 13-25, somewhat oblique, and upwardly 
falcate, oblong, rather broad, 7-11 cm. long, 1.7-2.4 cm. broad (the lower pinnae reduced, 
the terminal pinna lanceolate), unequally diminishing at the base, the posterior portion 
narrower and usually longer, mostly gradually curved to the midvein, the anterior portion 
more abruptly diminished, varying from straight or slightly curved on the lower pinnae to 
excavate on the wpper ones, abruptly narrowed at the apex, acute or acuminate, the 
margins thickened, finely undulate, serrulate toward the apex; midveins scaly below, the 
veinlets simple, nearly naked, 8-12 per cm.; sporophyls somewhat narrower, with very 
narrow pinnae.

DISTRIBUTION: Lesser Antilles and Trinidad. 
8. Danaea cuspidata Liebm. Vidensk. Selsk. Skr. V. 1: 307. 1849. 
A tall, rather slender plant; rhizome rather stout, the leaf-nodes close; leaves up to

blackish appressed scales; sterile lamina oblong or somewhat elliptic, 40-60 cm. long, up 
to 32 cm. broad, the rachis olive, sparsely scaly below, very narrowly winged in the upper 
half of the lamina; pinnae mostly separated by at least their own width, distant below, 
33-39, mostly at right angles to the rachis, slightly falcate, linear-oblong, up to 16 cm. 
long, and 1.7 cm. broad (the lower pinnae somewhat reduced and broader, the terminal 
pinna lanceolate), unequally diminishing at the base, the posterior portion longer and nar- 
rower, gradually curved to the midvein, the anterior portion more abruptly diminishing, 
varying from rounded on the lower pinnae to excavate on the upper ones, the apex 
acuminate, the margins revolute at the base, more or less revolute and repand along the 
sides, serrulate toward the apex ; midveins sparsely scaly, blackish, the veinlets forking or 
at least paired in origin, dark-colored, 18-20 per cm.
