  • Description

    Species Description - Closely and somewhat harshly tomentellate throughout. Rhizome elongate, apparently not scaly. Stems to a meter high, erect, slender, mostly simple, sparsely leafy, reddish, terete or slightly angled or sulcate in places. Leaves opposite or ternate, the lowest, if present, very small and rudimentary, but green; those of the middle portion of the stem sessile, to 8 cm. long and 3 cm. wide, obtuse at both ends, finely crenate, thick and somewhat fleshy, bright-green above, gray beneath, where the venation is very strong and more or less reddish, very strongly and crookedly anastomosing. Floral leaves reduced to ovate, thick, green, rigid bracts. Peduncles one-flowered, solitary in the axils of the bracts, erect, nearly 2 cm. long, slender. Calyx-tube hemispheric, 6 to 9 mm. broad, shorter than the triangular-acuminate, subequal rigid erect or slightly spreading calyx-lobes. Corolla scarlet, densely gray-pubescent, 3 cm. long, the greatest width, as pressed, 8 mm., the upper lip erect, about 8 mm. long, the lower lip very short, recurved-spreading. Basal gibbosity of corolla 3 mm. long, oval, erect and appressed. Corolla ventricoseto about the middle, or a little higher, slightly contracted above. Middle lobe of the lower lip 5 mm. broad, and not so long, the lateral lobes much broader. Upper lip about 1 cm. broad, deeply emarginate, somewhat narrowed at the base. Stamens moderately exserted, the anthers all coherent, but easily separable in pairs. Filaments attached at the base of the corolla. Two posterior glands of the disk large, slightly emarginate, subconnate, the lateral glands closely adjacent, ligulate, the anterior very small. Ovary conic, 5 mm. long, pubescent, like the style, which at length exceeds the stamens. Stigma shortly 2-lobed, recurved.
