Serruria acrocarpa is a rounded shrublet that grows to heights around 50 cm and resprouts after fire from its persistent rootstock.
The leaves are finely divided and nearly hairless, the leaf segments carried erectly. New growth is yellow-green and soft.
Hairy peduncles between 1 cm and 3 cm in long support the solitary, fragrant flowerheads. The specific name, acrocarpa, is derived from the Greek words akros meaning at the top and karpos meaning fruit, referring to the length of the peduncles, by saying fruit at the top.
Each flowerhead comprises 10 to 25 silvery to greenish yellow flowers. The unopened ones in picture can be seen curving inwards pronouncedly.
The peak blooming season is spring, although flowerheads may be seen for longer except autumn and early winter.
The Western Cape distribution ranges from the Cederberg to the southern Cape as far as Swellendam.
The habitat is fynbos flats and lower slopes where the plants grow in sandy and quartzitic soils. The species is not considered threatened in habitat early in the twenty first century (Manning, 2007; Bond and Goldblatt, 1984; iNaturalist; http://redlist.sanbi.org).
