pilose; bulb rather large, oval, blackish; leaflets roundish, firm, hollow-dotted, veiny, hairy beneath, ciliated, the medial petiolate, cuneate, subemarginate, the lateral smaller, rounded, oblique at base; petiole subcylindrical, hairy; scape equalling the leaf or shorter, bibracteolate; sepals ovate, erect, with reflexed points, 6 times shorter than the wide corolla; claws of the petals equalling the limb; stamens toothless. Petioles 1–2-uncial. Leaflets 6–12 lines long, 5–9 wide, sometimes spotted with red underneath. Sepals glabrous or pilose, sometimes with terminal calli. Petals with a yellow tube, and rosy or white limb.—Allied to the preceding, and especially to the smaller forms of O. variabilis, but at once known by its firmer and thicker, conspicuously hollow-dotted leaflets, pale when dry, and by the white-hairy petiole.
