Hesperantha bachmannii is a slender, cormous perennial of the west coast, the Little Karoo and the Eastern Cape. The leaves are narrow and soft-textured.
The flowers have inspired common names like ballerina and in Afrikaans aandblommetjie (little evening flower) or witrokkie (little white dress). The sweetly scented, nodding white flowers open in the afternoon. They are 2 cm in diameter, spirally arranged in a short spike. The corolla tube is curved while the tepals recurve abruptly at the corolla mouth. The long, thin, brownish yellow anthers and the three thread-like, white stigma branches can be seen, positioned well away from the corolla mouth.
Flowering happens from midwinter to early spring. This plant was photographed in August north of the Clanwilliam Dam (Manning, 2009; Vlok and Schutte-Vlok, 2010).
