description
Vegetative characteristics
Gasteria excelsa grows without a trunk, is prostrate to upright and reaches a height of 30 to 60 centimeters with a diameter of 60 to 75 centimeters. It sprouts from the base and forms dense clumps. The triangular-lanceolate, upright or slightly bent leaves form a dense rosette . The dark green leaf blade is 10 to 40 inches long and 10 to 18 inches wide. It is covered with indistinct white spots that are arranged in diagonal, (rarely) almost invisible stripes. It is seldom striped. The epidermis is smooth. The leaf margin is often very sharp, cartilaginous and finely serrated. The tip of the leaf is pointed or bluntly rounded and has an attached tip. Young leaves are two-lined, densely spotted with white, spreading, ribbon-shaped and warty.
Inflorescences and flowers
The inflorescence is a very large spread panicle and reaches a length of 100 to 190 centimeters. Side branches are erect, rarely horizontal, and spread out. The light pink, rarely white flower envelope is 22 to 26 millimeters long. Your bulbous part is narrowly ellipsoidal, has a diameter of 6 to 7 millimeters and extends over a little more than half the length of the flower envelope. Above it is constricted to a tube with a diameter of up to 5 millimeters. The stylus does not protrude from the flower envelope.
The flowering time is in the middle of summer.
Fruits and seeds
The fruits are 17 to 20 millimeters long and 8 to 12 millimeters wide. They contain seeds 4 to 5 millimeters long and 2 to 3 millimeters wide .
Systematics and distribution
Gasteria excelsa is widespread in the South African province of Eastern Cape in subtropical thickets and rocky river valleys.
