description
Vegetative characteristics
Aloe bulbicaulis grows easily and without trunk. Their base is enlarged towards the end of the growing season and forms an onion 8 to 10 centimeters in diameter. The approximately 16 ovate-lanceolate leaves form rosettes and usually die in the dry season. The bright green, longitudinally striped leaf blade is about 50 centimeters long and 15 centimeters wide. The leaf surface is smooth. The teeth on the whitish, cartilaginous, 1 to 2 millimeter wide leaf margin are 1 millimeter long and are closely packed together.
Inflorescences and flowers
The inflorescence consists of three to four (rarely up to seven) branches and reaches a length of about 60 centimeters. The rather dense, narrow cylindrical grapes are 10 to 20 centimeters long and 7 centimeters wide. The ovoid, pointed bracts have a length of about 12 millimeters and are 8 millimeters wide. The pale yellow to pinkish red or brownish yellow flowers are on approximately 20 millimeter long peduncles . The flowers are up to 40 millimeters long and rounded at their base. At the level of the ovary , the flowers have a diameter of 9 to 11 millimeters. Above it, they are narrowed to 6 to 8 millimeters, then expanded to 9 to 11 millimeters and finally narrowed again towards the mouth. Your outer tepals are not fused together over a length of 12 to 13 millimeters. The stamens and the style protrude up to 1 millimeter from the flower.
Systematics and distribution
Aloe bulbicaulis is common in Angola , Malawi , Tanzania , Zaire and Zambia on grasslands in open woodlands at altitudes of 1200 to 1620 meters.
