摘要：

An obligatory cremnophyte, Delosperma expersum var. decumbens is transferred to the genus Drosanthemum and raised to species level. Drosanthemum decumbens grows on upper quartzitic sandstone cliff faces of the Table Mountain Group (Cape Supergroup) in the Ceres and Worcester region of the Western Cape, South Africa. It differs from Drosanthemum expersum by its re-sprouting lignotuber, procumbent to pendent stems, shorter pedicels 10-15 (-35) mm long, and fruiting capsules turning reddish before drying.
