Pedicels 14–18 mm long, c. 2 mm thick; corolla (30–)60–120 mm wide, with a short tube, c. 6 mm wide, a broad, flat limb and broadly triangular, reflexed lobes; limb and lower part of lobes basically yellowish with an intricate pattern of more or less concentrically arranged dark purple dots, which are usually dense but sometimes almost absent and become larger and more widely spaced in an arc in the middle of each lobe; margin of corolla and the apical portion of the lobes usually uniformly purple or greenish-brown, with a fringe of long club-shaped purple hairs that also border them on the inner side and extend in five radial lines from the sinuses between the lobes to the outer rim of the tube. Outer corona-lobes acutely bifid and hairy on the inner side; inner lobes strap-shaped in their middle portion, joined above the staminal column, minutely tuberculate.
