Vegetative characteristics
Kalanchoe velutina is a perennial plant that can reach heights of up to 100 centimeters. It is completely enveloped with dense, short-bristled, whitish or rust-colored hair up to 0.5 millimeters long and rarely bald. Their upright shoots are stem-round to almost square and dark brown below, at the top they are almost stem-round and reddish brown to rust-colored. The thick, fleshy, upright to spreading leaves are petiolate. The petiole is 1 to 3 inches long. The very variably shaped leaf blade is linear, lanceolate or oblong. Its tip is blunt to rounded, the base is narrowed. The leaf margin is whole or irregularly serrated.
Generative characteristics
The inflorescence consists of even cymes . It is 8.5 to 10 inches long and 6 to 15 inches wide. The upright, yellow, orange-yellow to reddish brown, densely coarse-bristled flowers are on 4.5 to 10 millimeter long peduncles . Your fleshy calyx tube is 1.7 to 3 millimeters long. The triangular, pointed thorn-pointed calyx lobes are 1 to 2.5 millimeters long and about 1.5 millimeters wide. The corolla, which is swollen and rounded at the base , is square and narrowed above. The corolla tube is 11 to 20 millimeters long. Their egg-shaped to obovate or rounded, blunt, thorn-pointed corolla lobes are 3 to 7.5 millimeters long and 1.8 to 5.5 millimeters wide. The stamens are attached to the upper part of the corolla tube. The top of them protrude from the flower. The ovate-elongated anthers are 0.5 to 0.7 millimeters long.
