Comments

Perianth segments broadly ovate, blunt, only very slightly mucronate, a little inflexed, somewhat creased, overlapping half; the inner segments more narrowly ovate, more strongly inflexed, more thickly creased, a little twisted; corona shallow, widely expanded, heavily ribbed, opening faint sulfur yellow, becoming white, closely frilled.

From a catalog: “Large flat soft sulfur cup soon fades to creamy white.”
