Vegetative characteristics

Their strong, upright shoots are woody and up to 2 centimeters in diameter. The sitting, bare, very thick, fleshy, stable leaves that are crowded at the tips of the shoots are frosted and waxy gray. Your obovate-spatulate or semicylindrical leaf blade is 3 to 11 inches long and 0.8 to 2.5 inches wide. Their tip is blunt to wedge-shaped, the base gradually narrowed. The leaf margin is entire.
Generative characteristics
The inflorescence consists of small, very dense panicles and is 2 to 5 centimeters long. The stiffly upright inflorescence stalk reaches a length of 8 to 25 centimeters. The upright flowers are on fleshy, red glandular-hairy, 2.5 to 6 millimeter long pedicels . The green calyx is soft, glandular and hairy, the calyx tube 0.2 to 1.4 millimeters long. The egg-shaped triangular calyx lobes are 1.2 to 3.5 millimeters long and about 2 millimeters wide. The urn-shaped corolla is bald to glandular hairy, white, yellowish, pink to dull reddish. The corolla tube is 2.5 to 5 millimeters long. Their oblong obovate corolla lobes have a length of 3.5 to 6 millimeters and are just as wide. The stamens are attached above the center of the corolla tube and do not protrude from the flower. The kidney-shaped anthers are 0.8 to 1 millimeter long. The linear-triangular nectar flakes have a length of 1.7 to 2.5 millimeters and are 0.8 to 1.2 millimeters wide. The carpel has a length of 1.2 to 1.9 millimeters.
