Cape Province: South-Western Region; Montagu Div., near Montagu 
Baths, fl. Aug. 1924, Mary M. Page (Bolus Herbarium, No. 17693); 
H. H. W. Pearson (National Botanic Gardens, No. JqMp). 
This species flowered freely on the rockery at the South African Pavilion 
at Wembley in August and September, 1925. The plants there, however, 
were more luxuriantly grown than the wild specimens I have selected as

genus Delosperma, N.E.Br., and should probably be included in it rather 
than in Mesembrianthemum.
