The long, yellow-green wiry and curving petals of the Brachystelma macropetalum flower can be observed in this photo. Macropetalum means large petals in Latin. The leafy plant may grow to 60 cm from a perennial rootstock.
The hairy leaves are ovate, growing on short petioles and point upwards. Cream-coloured veins prominent on the lower leaf surfaces are covered in fine whitish hairs as can be seen in the picture. The leaf tip is acute while the leaf base is rounded or tapering abruptly.
Flowers of B. macropetalum appear solitary in leaf axils or at the nodes, each on a long, hairy peduncle with a leaf-like bract. The five green and hairy sepals with acute tips may either ascend or spread as they do in this specimen. They are narrow, almost linear and less than half as long as the petals. At the base of the petals where they spread slightly, they are covered in tiny spots. At the petal tips tiny narrow sections occur that curve away from the petal’s general direction. In the flower centre the dark purplish staminal column comprising the erectly lobed outer and inner coronas is visible. The inner corona is longer than the outer one.
The seed follicles that appear later are paired and cylindrical, slightly diverging from the base (JSTOR).
