description
Sansevieria gracilis grows as a perennial , succulent plant with runners above the ground that are 15 to 90 centimeters long and 8 millimeters thick. They are covered with scales 12 to 25 millimeters long, some of which merge into leaves. The trunk is 2 to 8 centimeters high. The eight to twelve leaves standing on one shoot are tightly spiraling, rising or spread out. The simple leaf blade is 25 to 80 centimeters long and 6 to 9 millimeters thick. It is 5 to 12.5 centimeters long from the base and has a hollow groove and is cylindrical at the top. It is dark green, sometimes provided with indistinct, narrow, darker transverse bands and slightly darker longitudinal lines. It gradually ends in a brown or whitish spider tip 2 to 6 millimeters long. The spreading edge is white membrane-like. The leaf surface is smoothly furrowed with age.
The single- eared inflorescences are up to 30 centimeters high. They have a light green stem. The panicles are loosely covered with up to two flowers per tuft. The bract is lanceolate or linear-lanceolate, somewhat pointed and 2 to 3 millimeters long. The flower stalk is 1 to 2 millimeters long. The bracts are white. The flower tube is 2 to 2.5 inches long. The tips are 1 centimeter long and a little above.
