Stems (above ground) 30-70(-150) mm long, (3-)5-15 mm thick, decumbent to erect above soil often from horizontal rhizomes 50-300 mm long, grey-green to reddish towards tips, ± terete, obtuse; tubercles 1.5-3.0 mm long, spreading, deltoid, ± conical and joined right near base into 6-9 often spiralling rows along stem, tapering abruptly towards middle into slender lanceolate tooth 1-2 mm long. Inflorescence of 1-5 flowers developing in gradual succession, arising near base of stem from small peduncle up to 7 mm long with slender acuminate bracts 2-3 mm long without lateral teeth; pedicel 2-8 mm long, 1.5 mm thick, spreading with upturned apex so that flower facing slightly upwards; sepals 4-7 mm long, ovate-acuminate. Corolla 20-30(-35) mm diam., campanulate; outside smooth, pinkish to cream, with 3-5 longitudinal veins running down each lobe; inside cream densely spotted with red-brown becoming more finely spotted on whitish towards base of tube, covered on lobes and to halfway down tube with cylindrical ± obtuse papillae up to 1 mm long and usually horizontally banded with red-brown on cream, each with a small apical bristle; tube 8-9 mm long, 7-9 mm broad at mouth, cupular, cylindrical; lobes 5.5-10.5 mm long, 6-11 mm broad at base, spreading with apices recurved, deltate, acute. Corona 5.0-6.0 mm tall, 5.5-7.0 mm broad, without basal stipe; outer lobes 1.5-2.0 mm long, ± rectangular to deltoid and usually notched at apex, dark maroon; inner lobes 2.0-3.5 mm long, reddish becoming maroon towards apex, adpressed to backs of anthers near their base, dorsiventrally flattened below and somewhat dorsally swollen at base, above connivent then diverging above middle or remaining erect, becoming terete and tapering slightly to slightly swollen bristly-tuberculate apex.
