description
Vegetative characteristics
Kalanchoe beharensis are 2 to 3 meter high shrubs . The basal, simple shoots have a resinous bark . Above it they branch out, are erect, strong and downy-haired, with a diameter of 2 to 12 centimeters. The shoots have conspicuous leaf scars with sharp extensions on both sides . The few leaves stand on 4 to 10 centimeters long, fleshy, rotating petioles and are densely packed at the shoot tips. The leaf blade is 7 to 40 inches long and 8 to 30 inches wide, glabrous, bluish to more or less dense white to brownish and downy with star-shaped hairs . It is pointed at the top and edged at the base.
Inflorescences and flowers
The many-flowered, axillary inflorescences form panicles 20 to 30 centimeters high . The inflorescence stalk becomes 40 to 50 centimeters. The flowers sit on 4 to 13 millimeter long peduncles , protrude in all directions and are very downy hairy. The tubular calyx is yellow-green with reddish lines and has triangular, pointed tips. The urn-shaped corolla is pink-green to green-yellow and forms a 6 to 10 millimeter long tube. The lobes are egg-shaped, pointed and are 5 to 13 millimeters long and 3 to 6 millimeters wide. The stamens are attached near the tip of the corolla tube and protrude from the tube. The carpel is 5 to 12 millimeters long. The stylus has a length of 5 to 10 millimeters.
Fruits and seeds
The fruits are upright follicles that contain numerous, obovate, 0.7 millimeter large seeds .
