Sepals lanceolate, acuminate, ±4 mm long. Corolla erect, in cult, up to 58 mm long(type in untreated dry state less than 30 mm long), with tube slightly longer than lobes; tube subglobosely inflated near base, 5-8 mm diam., subcylindric above and slightly expanded towards mouth, glabrous, verrucose-spotted and glabrous within; lobes linear, connate at apex forming cage-like structure, sometimes puberulous outside for short length near base, then, sometimes, for short space ciliate, with long, caducous, clavate-vibratile hairs, puberulous above on inner surface with margins somewhat infolded, appearing very narrow. Corona slightly united and cupular at base; outer lobes sub-erect, up to about 2 mm long, divided nearly to base into 2 slender lobules; inner lobes connivent-erect, about 2 mm long, linear-oblong to spathulate.
