Didelta carnosa var. carnosa is a sprawling to rounded shrublet with fleshy branches. It has narrowly elliptic leaves that taper towards the base. These leaves are fleshy, smooth and hairless. The leaf margins are rolled under and have rounded tips. The specimen in picture shows green to yellow-green leaf colour on older leaves while the young growth has whitish grey foliage.
The flowerheads appear solitary with two rows of noticeable bracts. The outer five bracts are broad, opening widely in a saucer-like base for the flowerhead. The inner row is narrowly lanceolate and toothed, tapering to acute tips. There are also a few buds to be seen in various stages of opening with the outer bracts enveloping the corolla.
Flowering occurs from midwinter to early summer. The distribution is coastal dunes and flats in sandy soil on the west coast (Manning, 2009; Manning and Goldblatt, 1996).
