Vegetative characteristics
Kalanchoe yemensis is a perennial , robust plant that is bald at the bottom and hairy glandular at the top, reaching heights of 50 to 100 centimeters. Its stem-round, bare shoots branch out from the base. The sitting leaves are bare. Their narrow, elongated to lanceolate or egg-shaped leaf blades are 4 to 18 inches long and 1.5 to 6 inches wide. Its tip is blunt to pointed, the base embracing the stem. The leaf margin is whole to cupped or rarely bluntly serrated.
Generative characteristics
The glandular-hairy inflorescence is equilateral and 5 to 8 inches long. The upright flowers are on 1 to 5 millimeter long peduncles . Their sparsely glandular, long-haired calyx tube is 0.5 to 2 millimeters long. The elongated egg-shaped to egg-shaped-triangular, pointed calyx lobes are 4 to 9 millimeters long and 1.5 to 4 millimeters wide. The sparsely glandular, long-haired corolla is bright yellow, pale yellow or orange-yellow. The cylindrical corolla tube is 8 to 13 millimeters long. Their spread out, egg-shaped corolla lobes have an attached tip and are 5 to 10 millimeters long and 2.5 to 8 millimeters wide. The stamens are attached to the throat of the corolla tube. The upper stamens protrude slightly from the flower. The anthers are about 0.5 millimeters long. The linear nectar flakes are 3.5 to 4.5 millimeters long. The carpel has a length of 8 to 10 millimeters. The stylus is 2 to 4 millimeters long.
