description
Vegetative characteristics
Gasteria acinacifolia grows stemless, is prostrate to upright and reaches a height of 25 to 75 centimeters with a diameter of 65 centimeters. It is single or sprouts and forms small groups. The upright, spreading and sometimes sickle-shaped leaves form rosettes . The dark green, keeled leaf blade is 22 to 60 inches long and 4.5 to 10 inches wide. It is covered with dense white spots arranged in diagonal stripes. The epidermis is smooth and rarely warty. The finely serrated and only sometimes entire leaf margin is cartilaginous. The pointed tip of the leaf is rarely rounded. Young leaves are arranged in two rows. They are band-shaped, spreading to erect, warty and rarely smooth.
Inflorescences and flowers
The differently trained inflorescence reaches a length of up to 100 centimeters. Usually it is a panicle with a flat top. The branches of the inflorescence are spread horizontally to upright. The inflorescence is 35 to 45 millimeters (rarely up to 50 millimeters) long and has a diameter of 5 to 9 millimeters. Your bulbous part is narrow ellipsoid and extends over half the length of the flower envelope. Often it is not constricted or indistinctly bulbous. The 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 trimmed or bluntly rounded fruits are 35 to 43 millimeters long. They contain seeds 6 to 8 millimeters long and 5 to 6 millimeters wide .
Systematics and distribution
Gasteria acinacifolia is distributed in the South African province of Eastern Cape in coastal dune thickets.
The first description by Joseph Franz von Jacquin under the name Aloe acinacifolia was published in 1811. Adrian Hardy Haworth placed the species in the genus Gasteria in 1819 .
