The corolla tubes of Dyschoriste thunbergiiflora flowers are narrow where they emerge from the small calyces that split halfway down their length into small, about linear lobes. The corollas widen for more than half their length before assuming a wide cylinder-shape up to the spreading of the petal lobes.
The flower tubes bend down slightly in their upper parts, the flowers being two-lipped, not radially symmetrical (Blundell, 1987; iNaturalist).
