Vegetative characteristics
Kalanchoe streptantha is a sturdy, perennial , completely bald plant that reaches heights of up to 1.2 meters. Its strong, prostrate, upright shoots are 2 to 3 centimeters in diameter and branch out from the base. The thick, fleshy, light green to green bluish, red to bluish edged, whitish tinged and glaucous leaves are short stalked or almost sessile. The leaf stalk , slightly encompassing the stem, is 5 to 10 centimeters long. Your elongated lanceolate, obovate to obovate-lanceolate, purple-spotted leaf blade is 4 to 15 centimeters long and 1 to 7.5 centimeters wide. Its tip is pointed and wedge-shaped, pointed, the base gradually narrowed from the center. The leaf margin is whole or slightly cupped.
Generative characteristics
The inflorescence consists of little-flowered, evenly- shaped panicles and reaches a length of 10 to 15 centimeters. The inflorescence stalk is up to 30 centimeters long. The pendulous flowers are on 6 to 25 millimeter long flower stalks . The tubular calyx is green or yellow, red-edged and sometimes hairy-glandular. The calyx tube is 10 to 15 millimeters long. The ovoid-triangular, pointed calyx lobes are 4 to 9 millimeters long and 6 to 8 millimeters wide. The corolla is yellow, the corolla tube 30 to 36 millimeters long. Their ovate to elongated, very blunt and thorn-pointed, spread out corolla lobes are 9 to 12 millimeters long and 5 to 6 millimeters wide. The stamens are attached below the center of the corolla tube and protrude from the flower. The egg-shaped anthers are 1.5 to 2.5 millimeters long. The more or less square nectar flakes have a length of 1 to 2 millimeters. The carpel has a length of 8 to 13 millimeters. The stylus is 25 to 28 millimeters long.
