Lygodium venustum Sw. Jour. Bot. Schrad. 1801' : 503. 1803
Primary rachis subterete, usually yellowishstramineous, very narrowly marginate, up to 2.5 mm. in diameter, pubescent; primary branches up to 1 cm. long, densely pubescent, the terminal bud usually dormant; sterile secondary (geminate) pinnae petiolate (1.5-3 cm.), oblong or broadly oblong, 15-25 cm. long, 8-20 cm. broad, once-pinnate, acute or acuminate, the rachis nearly straight, densely pubescent, slightly alate toward the apex ; tertiary segments 5-8 pairs, approximate or mostly apart, slightly smaller toward the apex, all but the uppermost stalked, deltoid-ovate from a cordate base, 4—10 cm. long, 1.5-4 cm. broad at the base, the costa nodose-articulate at the base and emitting a dichotomous branch upon either side, the segment thus subpalmately 5-lobed, the middle lobe greatly elongate, usually at least twice as long as the lateral, lanceolate to oblong-lanceolate, 1-1.8 cm. broad, acute or obtuse, the margin deeply crenate-serrate or sometimes pinnately lobed, the lobes or crenations close, denticulate-serrate ; costae elevated, stout, nearly straight, excurrent to the apex, pilose or pubescent; veins commonly opposite, or subopposite, very oblique, elevated, subpinnately branched, the branches close, pilose or pubescent, the hairs of the lower surface usually much shorter ; leaf-tissue herbaceous, usually subopaque, glabrous or short-pubescent. Fertile secondary (geminate) pinnae similar to the sterile or often bipinnate, the lower tertiary' segments with shorter basal lobes or 1-3 pairs of short mostly opposite quaternary segments, the lowest of these inequilateral and often subpalmately lobed ; sporangiophores solitary upon the mostly shallow lobes, serrate, up to 8 mm. long; spores minutely verrucose.
Type locality : Brazil .

Rachis subterete, stramineous to yellowishbrown , very narrowly marginate, up to 2.5 mm. in diameter; primary branches 5-10 mm. long, sparingly pubescent ; sterile secondary (geminate) pinnae petiolate (0.5-3 cm.), broadly ovate to deltoid-ovate, 15-28 cm. long, 10-18 cm. broad, once-pinnate, acuminate, the rachis subflexuous, slightly or densely pubescent, foliaceo-marginate toward the apex ; tertiary segments 5-8 pairs, approximate or apart, the upper ones gradually smaller, all but the uppermost petiolate, elongate deltoidovate or deltoid-lanceolate from a cordate base, the larger ones 3-9 cm. long, the costa not nodose-articulate at the base, emitting alternately upon each side a dichotomous branch, the segment thus subpalmately 5-lobed or by the further division of the branches rarely 7-9-lobed, the middle lobe invariably the longest, lanceolate to linear-oblong, 5-15 mm. broad, acutish or obtuse, crenate or closely and obtusely lobed, the margins bluntly or sharply denticulate ; costae elevated, stoutish, usually flexuous, excurrent to the apex, pilose or often sparsely so below ; costulae and veins alternate, the latter very oblique, repeatedly dichotomous or subpinnately branched, the branches close, sparingly pilose or often conspicuously so with numerous short hairs intermixed ; leaf-tissue membrano-herbaceous, lustrous at least above, glabrate or minutely pilose. Fertile secondary (geminate) pinnae mostly equaling the sterile, bipinnate at the base or often so nearly throughout, the lower and middle tertiary segments oblong to narrowly deltoid, with 1-6 pairs of mainly alternate quaternary segments, the lowest of these inequilateral, often subpalmately lobed ; sporangiophores solitary, serrate, up to 8 mm. long ; spores minutely verrucose.
