Cape Province: South- Western Region; Riversdale Div.,? exact locality 
uncertain, “probably Klein Karroo,” fl. Nov. 1926, Dr John Muir, 3969. 
Described from two living branches from Dr Muir’s garden with four 
flowers and one capsule, probably of the previous year, but in perfect con- 
dition. The very narrow cell-wings, scarcely more than a narrow mem- 
branous margin to the cell- walls, bring this species into very close relation- 
ship with the genus Delosjperma and it might be regarded as a connecting 
link between this genus and Mesembrianthemum. 
Dr Muir has had the plant in cultivation since the beginning of 1926.
