This member of the Aizoaceae family was described by Nicholas Edward Brown in 1926. It's found in southern South Africa, where it grows in grit or other well drained soil with little to some water and quite some sun. The stem can grow to eight centimetres in diameter and the plant up to 25 centimetres height. The flowers are yellow, and beside from seeds, it can also be reproduced by cuttings.
The genera name from Latin Phyllo; 'leaf' and bolus; 'a large pill'. The species is named after Prof. Henry Harold W. Pearson, 1870-1916, an English botanist, working in South Africa.
