Crassula pseudohemisphaerica is a tiny succulent that grows a few almost circular leaves. Slightly obtusely pointed at their tips, the leaves are pressed to the ground in a low-growing rosette. The leaf margins are ciliate, i.e. they are adorned with tiny creamy hairs. Maroon to purple spots are scattered upon the leaf surfaces.
Some basal branching creates a few clustered centres or rosettes in mature plants, such as this one. A common Afrikaans name of miskoekie (dung patty) for this plant was encountered.
From each of the rosettes an erect flower stem produces tiny flowers in thyrse-shaped inflorescence. A few small opposite leaves are spaced along the lower part of the flower stem.
The species distribution is inland from Namaqualand across the Karoo and Little Karoo to the Eastern Cape in the Kouga Mountains.
