description
Vegetative characteristics
Kalanchoe lanceolata is an annual or perennial , bald or glandular-downy-haired, sometimes sticky plant that reaches heights of 0.2 to 2 meters. Their usually simple, upright shoots are usually square or slightly narrow winged at their base. The green or yellowish green, glabrous or glandular-downy-haired leaves are sessile. Their obovate to narrowly elongated, lanceolate, elliptical to ovate spatulate leaf blades are 3 to 30 centimeters long and 1 to 10 centimeters wide. Its tip is pointed or blunt, the base wedge-shaped, descending and half-encompassing the stem. The papery to membranous leaf margin is whole or wavy, serrated or notched.
Generative characteristics
The inflorescence consists of glandular-downy, paniculate cymes and reaches a length of 35 to 50 centimeters. The usually upright, but sometimes pendulous flowers are on glandular-hairy, 1 to 10 millimeter long pedicels . The glandular-hairy calyx is yellow, the calyx tube 1 to 11 millimeters long. The egg-shaped, egg-shaped-lanceolate or elongated elliptical, pointed calyx lobes have a length of 2.5 to 13 millimeters and are 1.5 and 4.5 millimeters wide. The glandular-hairy, salmon-pink, orange-yellow or yellow corolla is greenish in the lower part. The cylindrical, in the lower half inflated and square corolla tube is 8 to 15 millimeters long. Their obovate or lanceolate corolla lobes have an attached tip. They have a length of 2 to 6.5 millimeters and are 1 to 4 millimeters wide. The stamens are attached above or in the middle of the corolla tube and do not protrude from the flower. The elongated anthers are 0.5 to 1 millimeter. The linear, pointed nectar flakes are 2.5 to 4.6 millimeters long and 0.2 to 0.3 millimeters wide. The spindle-shaped carpel has a length of 5 to 9 millimeters. The stylus is 0.5 to 1.5 millimeters long.
The club-shaped seeds reach a length of 0.5 to 0.7 millimeters.
