Fl. 107mm wide; perianth and other petaloid segments in two or more whorls; the outer whorl broadly ovate, blunt, slightly mucronate, spreading, plane or with margins a little incurved, smooth and of heavy substance, overlapping half; the inner segments narrower, concave, successively shorter and more strongly inflexed towards center; corona segments opening yellow, becoming white, half the width and length of the petaloid segments, interspersed among them and clustered toward center, the innermost crumpled and folded. The ruffled shorter coronal segments open lemon yellow and take some time to fully whiten to true 4W-W. This whitening is accelerated in sunny warm seasons.
