The yellow flowers Pleiospilos compactus subsp. canus grow solitary on very short or no stalks from between the paired leaves.
The narrowly paddle-shaped petals are long and sometimes white near the base as in the photo. They grow in about two whorls around the flower centre, soft and arching out from angled-up at the base. Flower diameter is about 3 cm, the number of petals said to be more than eighty.
Ring-shaped nectar glands, dark green in colour, surround the base of each of at least nine styles per flower (iNaturalist; http://www.llifle.com).
