description
Vegetative characteristics
Kalanchoe pubescens is a robust, perennial plant that reaches heights of 0.5 to 1.2 meters. It is completely and densely covered with white to reddish, long, simple, glandular hair . Their stalk-round, pure green, often red-purple striped shoots are erect, prostrate-upright or sometimes prostrate and strongly branched from the base. The fleshy, green leaves are petiolate to sessile. The flat, stem-encompassing petiole is 1 to 5 centimeters long. Your egg-shaped, elliptical to circular leaf blade is 3 to 15 inches long and 0.5 to 9 inches wide. Its tip is rounded to pointed, the base slightly truncated. The leaf margin is notched and serrated regularly.
Generative characteristics
The inflorescence carrying the brood buds consists of dense, multi-flowered panicles 15 centimeters wide. The pendulous flowers are on slender, 10 to 12 millimeter long flower stalks . The green calyx is spotted red-purple, the calyx tube is 3 to 6 millimeters long. The triangular to egg-shaped, pointed calyx lobes are 2.5 to 7 millimeters long and 3.8 to 4.8 millimeters wide. The bell-shaped, sometimes square corolla is pink, red-orange to yellow and often lined with reddish lines. The corolla tube is 14 to 30 millimeters long. Their ovate to triangular, blunt to marginalized corolla lobes are 4 to 13 millimeters long and 4 to 7 millimeters wide. The stamens are attached below the center of the corolla tube and protrude from the flower. The egg-shaped anthers are 1.2 to 2 millimeters long. The elongated to rectangular nectar flakes have a length of 1.2 to 2 millimeters. The carpel has a length of 13 to 18 millimeters. The stylus is 13 to 18 millimeters long.
The obovate seeds reach a length of about 0.7 millimeters.
