Pattern 6--central depression on the adaxial face and sharply projected abaxially
in Gorceixia decurrens.
Lamina of larger leaves 16-26 cm long, 11-16 cm wide, broadly elliptical, broadly cuneate at base, rounded and apiculate or shallowly retuse at apex, adaxially glabrate at maturity except persistently loosely sericeous on midrib, abaxially
densely and persistently appressed-tomentose with the hairs sessile or short-stalked and the crosspiece ca.
Costae prominulous, adaxially sulcate, rather curved abaxially
, moderately scaly, densely pilose.
It differs from the last, a specimen half its size, in a wider middle lobe of the glabella, which is also slightly more arched (tr.), and the eyes situated farther abaxially
. As little is known of the growth variation of the species, it is difficult to assess exactly whether they are conspecific.
Leaves are up to 3 m long with aculeus on the petioles and abaxially
on the rachises and pinna-rachises.
Leaves widely obovate to widely depressed obovate, widely elliptic to oblate, widely ovate-circular, very widely ovate to widely depressed ovate, length/width ratios 1.2-0.8:1; apices commonly retuse, sometimes rounded; crenate-dentate; leaves when yet unfolded adaxially subglabrous, with minute glandular hairs throughout, pubescent and tomentose over teeth, and puberulent here and there on surface, pubescent from a few teeth apices, tufted on midvein and some secondary veins, when newly unfolded adaxially subglabrate except at apex and base; abaxially
pubescent (rays planar), golden-tomentellous, later glabrate, glabrescent, gray trichomes, with primary to fifth order veins raised; white striae (wax?) along veins.
Leaves 12 to 14 in number, suberect-recurved, forming a broadly crateriform rosette; sheaths broadly elliptic, 19-25 x 17-20 cm, subdensely pale-brown lepidote on both sides, greenish or sometimes reddish near the apex; blades linear, not narrowed toward the base, 30-44 x 11-14 cm, glabrescent abaxially
, inconspicuously and sparsely white lepidote adaxially, rose-red throughout, more so adaxially or green toward the base and reddish near the apex, bearing dark green, sparsely arranged irregular spots, apex broadly acute to rounded and apiculate, apiculous ca.
7 mm long; floral scales dorsally with two red transversal stripes (scale neck, callus); leaves abaxially
whitish from scabrid trichomes ca 0,5-0,75 mm long.
Dioecious trees; leaves 1.5-3.0 mm long, entire, glandular abaxially
; pollen cones terminal, single, 1-2 mm long, consisting of 2-4 opposite sporophylls; ovulate cones woody, 5-9 mm broad, 5-7 scales; seeds winged, 1-2 per fertile scale, 2-3 mm long.
glabrous or with resinous dots 2 1.
