Kalanchoe arborescens is a species of the genus Kalanchoe in the family of thick-leaf plants (Crassulaceae). Together with Kalanchoe dinklagei, it is the tallest species of the genus. The specific epithet arborescens comes from Latin and means 'tree-like growing'.
description
Kalanchoe arborescens forms small trees that can reach heights of up to 8 meters. The trunk is simple at the bottom with a diameter of up to 10 centimeters. At the top it is branched, with the fleshy and bare branches usually in threes and between 5 and 10 centimeters in length. The thick, fleshy and bare leaves are in threes or more or less alternate. The 1.5 to 3 centimeter long petiole is round. The almost circular, obovate to spatulate leaf blade is 1.5 to 4 inches long and 1 to 3 inches wide. It is rounded at the top and narrowed at the base. The leaf margin is entire.
The inflorescence is equilateral to pyramidal and 2 to 6 centimeters wide. The bald inflorescence stalk is 5 to 10 inches long. The upright to pendulous, bare flowers sit on 1 to 2 centimeters long flower stalks . The green calyx tube is about 4 millimeters long and ends in triangular, pointed lobes that are 4 to 5 millimeters long and about 6 millimeters wide. The thick, fleshy, pale green corolla sometimes has pale purple spots inside. The four-edged, about 9 millimeters long and 8 millimeters wide corolla tube has elongated triangular, pointed tips that are about 8 millimeters in size. The stamens are attached about in the middle of the corolla tube and all protrude slightly from the corolla tube. The elongated anthers are about 2 millimeters in size. The rectangular to linear nectar flakes are about 2 millimeters long and 0.5 millimeters wide. The elongated carpel is as long as the approximately 5 mm stylus .
