description
Vegetative characteristics
Aloe lensayuensis grows trunk-forming and is sparsely branched from the base. The prostrate trunk reaches a length of 50 to 75 centimeters and is 2.5 to 3 centimeters thick. The ten or so lanceolate, pointed leaves form a loose rosette . The bluish gray, occasionally pink tinged leaf blade is 30 centimeters long and 5 centimeters wide. Sometimes it is covered with a few scattered elongated white spots. The leaf surface is slightly rough. The white or reddish leaf margins are cartilaginous. The soft, white teeth on the edge of the leaf are 1 millimeter long and 2 to 10 millimeters apart. The yellow leaf sap dries brownish.
Inflorescences and flowers
The inflorescence has eight to twelve widely spread branches and reaches a length of about 75 centimeters. The lower branches are occasionally branched again. The loose, cylindrical grapes are 10 to 15 centimeters long and consist of five to twelve flowers. On crooked grapes, the flowers are one-sided. The ovoid-pointed bracts are 1 to 4 millimeters long and 1.5 millimeters wide. The pinkish red, conspicuously frosted flowers are on approximately 8 millimeter long flower stalks . They are 20 to 24 millimeters long and narrowed briefly at their base. At the level of the ovary , the flowers are 5 to 6 millimeters in diameter. Above this they are very slightly narrowed and finally slightly expanded towards the mouth. Your outer tepals are not fused together over a length of 6 to 7 millimeters. The stamens and the pen stand 2 to 4 millimeters out from the flower.
