Vegetative characteristics
Kalanchoe mandrarensis is a perennial plant that is completely covered with star-shaped, red-brown hair and reaches heights of 20 to 30 centimeters. Their prostrate, creeping, rooting shoots are woody at their base and have a diameter of up to 3 millimeters. The ascending branches are a bit fleshy. The fleshy, thick leaves are petiolate. The rotating petiole is 7 to 25 millimeters long. Their ovate to almost circular leaf blades are 1.5 to 2 inches long and just as wide. Its tip is rounded, the base broadly rounded to narrowed wedge-shaped. The leaf margin is sharply serrated with triangular, 2 to 3 millimeter long teeth.
Generative characteristics
The inflorescence consists of few-flowered cymes . The pendulous flowers are on flower stalks about 10 millimeters long . The calyx is wide, bell-shaped and the calyx tube about 5 millimeters long. The triangular, pointed calyx lobes have a length of about 3 millimeters and are 4 millimeters wide. The slightly fleshy, broadly bell-shaped corolla is cream-colored. The almost square corolla tube is 12 to 15 millimeters long. Their semicircular, upright corolla lobes are 4 to 5 millimeters long. The stamens are attached a little above the center of the corolla tube and do not protrude from the flower. The egg-shaped anthers are about 2 millimeters. The triangular, thick nectar flakes have a length of about 0.5 millimeters. The elongated carpel has a length of about 7 millimeters. The stylus is about 7 millimeters long.
Systematics and distribution
Kalanchoe mandrarensis is distributed in the south-east of Madagascar in the dry forest on rocks at heights of 600 to 900 meters.
