Perianth segments very broadly ovate in outline, blunt to rounded at apex, mucronate, white, spreading, plane, overlapping half; the inner segments more narrowly ovate, square-shouldered at base, somewhat truncate, scarcely mucronate, with margins wavy; corona bowl-shaped, smooth, white, with yellow at base and in a narrow band at rim, mouth tightly and irregularly frilled with rim entire.

Named because it is the last to bloom in Reed’s fields.
