Vegetative characteristics
Kalanchoe delagoensis is a robust, completely bare, biennial or more or less perennial , succulent plant that reaches heights of between 0.2 and 2 meters. The upright stalks are simple and round. The three-seated, seemingly opposite or alternate leaves are usually upright to straight when spread out. They are slightly cylindrical, a little rutted on the top and with a diameter of 2 to 6 millimeters reach a length of 1 to 13 centimeters. The leaf blade , narrowed at the base, is reddish-green to gray-green with reddish-brown spots. At the tip of the leaf margin there are two to nine small teeth with numerous brood buds .
Inflorescences and flowers
The compact, multi-flowered inflorescences form thyrses 10 to 25 centimeters long . The slender flower stalk is between 6 and 20 millimeters long. The hermaphrodite flowers are hanging. The reddish to green and red-striped petals are fused together like a bell. The 2.5 to 6 millimeter long corolla tube ends in sharply pointed, triangular-lanceolate corolla lobes 5 to 10 millimeters long and 3.7 to 5.7 millimeters wide. The stamens are attached below the center of the corolla tube and do not protrude beyond the tube. The 2 to 2.5 millimeters large anthers are egg-shaped. The nectar flakes are 0.7 to 2 centimeters long and are half-round to square with a rounded tip. The oval-elongated carpel is 5.5 to 6.5 millimeters long. The stylus has a length of about 2 millimeters.
Fruits and seeds
