Flower buds up to 8 cm across, cupule 2.5-3 cm high, 4-6 cm wide, bud scales up to 5.5-7 cm long. Flowers 15-20 cm wide and 7-9 cm high when expanded. Perigone lobes light reddish brown, 4-6 cm long and 5-7 cm wide, white warts a mixture of larger circular with oval ones, about 10-12 along a transverse line halfway the lobes, mixed with numerous white dots. Diaphragm c. 1-1.4 cm broad, c. 7 cm in diameter, strongly curved inwards along the opening, which is about 5/6th as wide as the apex of the perigone tube; upper face rather densely randomly covered with oblongish white warts. Disk of column c. 2 cm above the base of the perianth tube, 3.2-4.5 cm in diameter including the rim, exposed while the flower is opened; rim of disk with a 3-5 mm high raised part. Processes about 14-20(-30), sometimes almost missing in the centre of the disk, 3.5-5.5 mm long, apex cylindric, with bushy cilia. Neck of column 1.3-1.8 cm diameter, narrower in male flowers. One prominent annulus, 3 mm broad, 30-38 mm diameter around the base of the column. Perigone tube c. 2.5 cm deep, 5 cm wide; ramenta at the inner side in about 12 rows, little stalked outgrowths, 0.5-1 mm high, multilobed at apex, virtually absent near the base of the perianth tube, close to the annulus; in a 1 cm wide zone below the diaphragm with short, warty lobed, whitish, 2-3 mm wide warts. Male flowers with 10-15 anthers, relatively large for such small flowers, not hidden in a sulcus as in the larger-flowered species, but attached rather close to the lower margin of the disk; corresponding with each anther in the central column a deep groove which runs down below the anther to the column base. Female flowers with ovary 2.5 cm wide at apex, 1.0 cm high, above the annulus without grooves or with very faint ones, less room under the corona (overhang) of the disk than in male flowers, on its lower side a papillose stigmatic zone.
