1 mm diam.; petiole 5-18 mm long, slightly smaller or equal to rachis; 1 extrafloral nectary, vinaceous to purple, stipitate, pyramidal, located on the rachis between the proximal pair of leaflets, 1.5-2.5 mm long; rachis 4-8 mm long; leaflets discolorous, 2 pairs, chartaceous, adaxial surface puberulous, abaxial surface villose, ovate to elliptic, 13-32 X 6-15 mm, apex rounded to acute, base oblique, venation penninervous.
Wings are chartaceous. Venation consists of a strong median longitudinal vein plus a system of fine, closely spaced subparallel veins curved upward.
Leaves 7.5-24.5 cm long; petiole 17-32 mm long; pulvinus 1-2.3 mm diam; rachis 4.5-21.5 cm long; interfoliolar segments 0.7-1.5 cm long; extrafloral nectaries absent; leaflets 12-18 pairs, chartaceous, pilosulose, 13-41 x 7-13 mm, elliptic, oblong-elliptic, obovate or suborbicular, venation brochidodromous, nervures 10-16 pairs, apex mucronate, base obtuse, margin revolute, ciliated.
0.2 mm, linear-lanceolate to subulate, dark-brown, dispersed, marginally entire; blades 9-22 x 3.0-5.8 cm, chartaceous, lanceolate to oblong-elliptic, basically obtuse to truncate, apically acuminate to cuspidate; blade scales 0.7-1.2 x 0.1-0.3 mm, linear to subulate, dark-brown, dispersed, marginally entire, only on blade margin; veins evident, 1-2-forked, 1-1.5 mm apart, diverging at 65-75[grados] from costa; hydathodes absent; fertile fronds 17-28 cm long; stipes 3/5-3/4 the frond length; fertile blades 4.5-10.5 x 1.3-2.8 cm, lanceolate, basically obtuse to truncate, apically acute; intersporangial scales absent.
0.4 cm, both pubescent; leaflets 4.5-6 x 2.5-2 cm, concolorous, chartaceous, lanceolate to elliptic, apex acuminate to rounded, margins entire, base rounded, venation penninerved, both surfaces pubescent with tector trichomes; tendrils simple.
0.5 mm, linear-lanceolate, brown to atropurpureous, marginally ciliate-dentate, the cilia 0.3-0.5 mm long; phyllopodia 7-10 mm long; fronds 34-53 cm long; stipes 1/4-1/3 of the frond length; stipe scales 0.5-1 mm long (to 2.5 mm on the first 1 (-3) cm of the stipe base with scales lanceolate or linear-lanceolate), ovate to rounded, black, marginally ciliate, with long-ciliate margin and small central body; blades 15-37 x 1.2-2.8 cm, linear-elliptic, chartaceous to subcoriaceous, basicaly cuneate to attenuate, apically acuminate; abaxial blade scales ca.
Inflorescence erect, simple, ellipsoid to cylindric, 6u8 x 4u5 cm, 30 to 45-flowered; floral bracts broadly ovate, acute, 18u28 x 10u20 mm, tightly imbricate except for the spreading apex, thin coriaceous to chartaceous, very brittle when dried, slightly nerved, sparsely appressed-lepidote, bright golden yellow; flowers erect, subsessile, mostly concealed by the floral bracts, spreading at ca 30[degrees] from the axis at anthesis; sepals elliptic, acute, 17u18 mm long, thin coriaceous, nearly even, the adaxial pair carinate and connate for 4u5 mm, yellow green; corolla erect, exserted beyond the floral bract at anthesis; petals cucculate, lingulate, obtuse, 24-25 mm long, yellow tipped white or pale yellow-green.
Capsule oblong-obovoid, 2.5-3.2 mm long, 1.4-2.0 mm wide, apex apiculate, tomentose, few sessile glandular hairs below, only apex outwardly chartaceous and inwardly with thin corneous endocarp extending ca.
