Perianth segments broadly ovate, blunt, only very slightly mucronate, pale yellow, a little inflexed, separated at base, sometimes overlapping at shoulder; the inner segments half as wide; corona split to base, the six segments almost as long as the perianth segments, opposite and closely overlying them, of more or less the same width, with the inner corona and perianth segments joined at the margins from base to shoulder, deeply bi-lobed, loosely ribbed, of a much darker yellow than the perianth, frilled, with the inner segments inflexed at apex. Resembles a larger and better-formed ‘Buttonhole’.
