description
Vegetative characteristics
Gasteria batesiana grows without a trunk, is prostrate to upright and reaches a height of 3 to 10 centimeters with a diameter of 8 to 30 centimeters. It is rarely solitary, sprouts from the base and forms small to large groups. The upright, later bent back, triangular-lanceolate to linear leaves are initially arranged in two lines and later form a rosette . The dark green leaf blade is 5 to 18 inches long and 1.5 to 4 inches wide. It is covered with white spots arranged in diagonal stripes. The epidermis is tightly wrinkled. The finely serrated and only sometimes serrated leaf margin is cartilaginous. The pointed tip of the leaf is rarely bluntly rounded and has an attached tip. Young leaves are ribbon-shaped, densely warty and bluntly rounded at the tip.
Inflorescences and flowers
The paniculate inflorescence reaches a length of 30 to 45 centimeters. The bracts have a length of 6 to 12 millimeters and are 2 to 5 millimeters wide. The flowers are on 9 millimeter long peduncles . The inflorescence is 30 to 40 millimeters long. Your bulbous part is narrowly elliptical, has a diameter of 6 to 9 millimeters and extends over half the length of the flower envelope. The light pink flower shell is striped white and green on the upper half. The stylus does not protrude or protrudes up to 5 millimeters from the flower envelope.
The flowering period extends from spring to mid-summer.
Fruits and seeds
The fruits are 16 to 20 millimeters long. They contain seeds 4 to 6 millimeters long and 2 to 3 millimeters wide .
Systematics and distribution
Gasteria batesiana is widespread in the South African provinces of Mpumalanga and KwaZulu-Natal on exposed, south-facing rocks in the bushveld .
The first description by Gordon Douglas Rowley was published in 1955. A distinction is made between the following varieties :
- Gasteria batesiana var. Batesiana
- Gasteria batesiana var. Dolomitica van Jaarsv. & AEvan Wyk
Gasteria batesiana var. Dolomitica
The differences to Gasteria batesiana var. Batesiana are: The linear leaves are 10 centimeters long and 1 to 2 centimeters wide. With turgescence they are convex on both sides. The tip of the leaf is blunt.
Gasteria batesiana var. Dolomitica is widespread on steep dolomite cliffs in the South African province of Mpumalanga. The first description by Ernst Jacobus van Jaarsveld and Abraham Erasmus Van Wyk was published in 1999.
