The dark green leaf blade is 24 to 36 inches long and 2.4 to 4 inches wide. It is indistinctly keeled asymmetrically and covered with dense white spots arranged in diagonal stripes. The epidermis is smooth. The leaf margin is cartilaginous and finely serrated. The tip of the leaf is pointed or pointed and has an attached tip. Young leaves are two-lined, spread out upright, ribbon-shaped, spread out, distinctly warty, with an attached tip.

The reddish pink flower envelope is 18 to 25 millimeters long. Your bulbous part is spherical-ellipsoidal, has a diameter of 6 to 7 millimeters and extends over a little more than half the length of the flower envelope. Above it is constricted into a tube with a diameter of 4 to 4.5 millimeters. The stylus does not protrude from the flower envelope.
The flowering time is spring.
