Glottiphyllum carnosum is a rare species of succulent plant, of the family Aizoaceae.

It is indigenous to arid areas between the towns of Calitzdorp and Oudtshoorn in the Western Cape, South Africa.

[1] This species has a pale, waxy layer on its leaves, which gives it a greyish colour.

Its seed capsules have a woody base, and a rounded domed top.

In contrast, G. carnosum has much thicker leaves, with a hunched tip, and it tends of offset and branch far more.
