Terrestrial, herbaceous, or slightly woody at base; stems weak, reclining or scandent, glabrous, granular-scabrous above or pubescent in the inflorescence only, up to 2.5 m. high; leaves relatively few, large, the upper ones usually not reduced in size, the blades thin, papery when dr>-, green, or purple beneath, glabrous above, minutely scaberulent beneath, especially on the veins, (3) 5.5-13 cm. wide by 12-32 cm. long, usually about thrice as long as wide, on distinct stout petioles 1-2.5 era. long, varying from ovate, broadly elliptic or oblong to suborbicular, the ape. acute, often short-acuminate, the base rounded, varying to cuneate or subcordate, the margins subcntire, sinuate-crenate, the yellownsh callosities slightly projecting beyond the margins as teeth, or slightly depressed, 1-4 per cm.; inflorescence 15 cm. long or less, often subcapitate, densely few-25(100-) flowered, the mature naked axis covered closely by the prominent roundish scars of the fallen flowers, appearing pedunculate, the stem naked below the lowest bract for a distance of 3-18 cm., the inflorescence often abruptly recurved and pendent; pedicels ascending-spreading, weak, 10-40 mm. long in fruit, short-bristly-pubescent, each normally with two short filiform bracleoles at or near the base; flower-bracts foliaceous but differing markedly in size from the foliage-leaves, oblong to ovate, 2-10 mm. mde, 10-24 mm. long, minutely toothed; flower 5.5-7 cm. long, including hj-panlhium and stamens; corolla "cardinal red," "orange red," "bright red," or "scarlet," the lobes usually yellow ("cadmium-orange") ^within?), glabrous within, thickly covered (rarely sparsely covered) without with short conic-inflated sharp hairs the same color as the corolla itself, the tube 28-39 mm. long, abruptly cured in bud, strongly curved to nearly straight in anthesis, narrowest in the pro.ximal third and gradually enlarged to a point somewhat aliove the middle, where abruptly enlarged to its ma.ximum width (%vhen pressed, 8-15 mm), the lobes deltoidacuminate, falcate, the distal part of the corolla strongly curved so that the united tips of the loljcs form, in the bud, a distinct curved beak, the two upper lobes 4-5 mm. wide at base, 81 2 mm. long, the lateral and lower lobes similar, shorter, 4-8 mm. long; filament-tube 40-55 mm. long, much e.xserted, hirsute near tip, glabrous below, the filaments distinct at base and united to the coroUa-tube; anther-tube 7-10 mm. long, cream-yellow (according to Austin Smith), incurved, the anthers densely white-tufted at tips, the hairs of the terminal tufts of the two_ shorter anthers concresccnt into a deltoid scale 2.5-3 mm. long, the backs of the anthers sparsely to densely hirsute in lines with white or pinkish hairs which may be 4 mm. long; h>n>anthium in anthesis hemispheric, rough-bristly or nearly smooth; fruit a depres.sed-globose, scarcely fleshy "Ijerry," broader than high, up to about 12 mm. in diameter; calyx-lobes linear, bristlypubescent, acute at tip, entire or minutely callosc-denticulate, 1-2.5 mm. wide, (4) 6-16 mm. long; seeds lenticular, about 0.7 mm. in diameter, foveale-reticulale, nearly circular in outline.
