Rich orange, becoming red ; yellow spotted with red at the throat ; truss good ; flowers large ; petal broad, smooth ; foliage very broad, glaucous green with distinct crimson edge. The habit distinctly that of the orchid-flowered varieties, but the smoothness and substance of the petals almost that of the gladiolus section.
