furfuraceo-pubescent, sparingly fibrillose with long tortuous linear dark-brown scales, the 
rachis similarly fibrillose throughout ; lamina lanceolate, fully bipinnate, about 90 cm. long, 
30-38 cm. broad in the middle, tapering in both directions, the apex acute, the base somewhat 
reduced ; pinnae about 40 pairs, nearly horizontal, sessile, the middle ones alternate, about 
2cm. apart on each side, ligulate, 17-19 cm. long, 2-2.5 cm. broad, the short-acuminate 
apex deeply serrate; lowermost pinnae subopposite, 4-6 cm. apart, 6-8 cm. long, 1-1.3 cm. 
broad ; secondary rachises with a few linear dark-brown light-margined scales toward the 
base, elsewhere with dark-brownish stellate light-centered scales mingled with yellowish 
hairs; pinnules of the middle pinnae 40-45 pairs, slightly oblique, mostly short-stalked, 
the upper ones constricted above the rounded base and unequally hastulate, the lower ones 
fully hastulate and cut to the costa, the basal divisions rounded and free ; margins subentire, 
only the apex of the pinnule regularly crenate-serrate; costae elevated, bearing stellate 
scales and hairs like those of the secondary rachis; veins 10-12 pairs, once forked near the 
base; sori 4 or 5 pairs, close to the costa; indusia dark reddish-brown, subhemispheric, 
open, firm, persistent; receptacle large, capitate. 
TYPE LOCALITY: Forested slopes of Finca Las Gracias, Yateras, province of Oriente, Cuba, 
altitude about 500 meters.

below, closer above, oval_to ovate, 1.5-2.5cm. long, 1-1.3 cm. broad, obscured at the apex 
by the short erect adnate fibrous stipe-bases of previous seasons; fronds 3 or 4, erect- 
spreading, broadly oblanceolate, bipinnate, 1-2 meters long, 20-40 cm. broad above the 
middle, the apex short-acuminate, the base gradually attenuate, the lower pinnae spaced, 
the lowermost vestigial and close to the caudex; primary rachis brownish or yellowish- 
brown, sulcate above, pubescent, unarmed except for the blunt protuberant bases of the 
minute basal pinnae; pinnae 30-45 pairs, close, horizontal, narrowly oblong-lanceolate, 
the largest 15-20 cm. long, 2.5-3.5 cm. broad, chartaceous, sessile, pinnatifid to the costa 
into about 30-35 pairs of segments below the deeply crenate attenuate apex, the costa densely 
covered with long yellowish-white hairs with whitish bullate scales intermixed ; segments 
oblique, oblong, slightly falcate, mostly adnate, rounded at the base, entire (or the lower- 
most sometimes sessile and unequally crenate), obtuse, glabrous above, below sparingly, 
hirsute and with numerous small whitish bullate scales; veins evident, 10-12 pairs, once- 
forked near the base or again half way to the margin, slightly hirtous ; sori 4-7 pairs, close 
to the costule ; indusia dark reddish-brown, deeply cyathiform, more or less pubescent, the 
margin even and somewhat constricted ; receptacle small, enclosed. 
TYPE LOCALITY: Monte Verde, Cuba. . : . . 
DISTRIBUTION: Known only from the province of Oriente, Cuba, occurring on partially 
wooded slopes in the region known as the Yateras. 
4. Cyathea pubescens Mett.; Kuhn, Linnaea 36: 164. 1869. 
Caudex stout, erect, up to 12 meters high, 15-20 cm. in diameter, prickly, densely tes- 
sellate with definite scars; fronds erect or erect-spreading, lanceolate, 2-2.5 meters long, 
40-70 cm. broad in the middle, tapering in both directions, the apex short-acute, reduced 
rather abruptly at the base, the pinnae extending nearly or quite to the caudex ; primary 
rachi$ brownish or castaneous, at the base chaffy with long narrow glossy brown scales and 
densely armed with stout curved spines, particularly upon the upper surface, the upper rachis 
rusty-puberulous and sometimes slightly muricate beneath, very densely yellowish-hirsute 
above with long filamentous yellowish-white scales intermixed; pinnae very numerous, 
approximate or somewhat imbricate, horizontal, ligulate, 20-35 cm. long, 2.5-3.5 cm. broad, 
sessile, rigid, comprising 60 or more pairs of segments below the serrate attenuate apex, 
the secondary rachis rusty-furfuraceous toward the base, rusty-pilose in the apical portion ; 
segments coriaceous, dull-green, paler below, contiguous, elongate-oblong, falcate, subacute 
or acute, adnate, the margins sharply crenate-serrate or biserrate and subrevolute, or the 
lowermost segments free and deeply crenate; costae rusty-furfuraceous at the base, pilose
