description

Drimia rotunda grows with bulbs on the ground surface or above ground that are wider than they are tall. They are succulent, greenish, or covered with thin, papery onion scales. Often groups arise through division. The numerous dark green, narrowly lanceolate leaves are semi-upright to spread out and appear after the flowers. Your slightly succulent leaf blade is up to 20 inches long and 0.7 inches wide. It has a thickened midrib.

The inflorescence reaches a length of up to 40 centimeters. The flower stem is up to 20 centimeters long. The flowers are loosely arranged. The narrow, lanceolate-linear bracts are 5 to 8 millimeters long and have three nerves at their base. Their variously shaped, thin spurs are 1.5 to 2 millimeters long. The flowers are on thin, 20 to 25 millimeter long peduncles . The spherical, greenish white to greenish brown flower envelope reaches a diameter of 7 to 8 millimeters. The stamens are subulate, the anthers ovate.
