Origin and Habitat: South of Warmbad, Namibia.
Habitat: Lithops dinteriSN|13190]]SN|13190]] grows in barren minerals terrains clinging to life in this harsh landscape. They live a precarious existence almost completely buried in the ground hidden beneath outcrops of coarse pegmatite, white, grey-white, pink, light brown and are very difficult to find in the field, especially when slightly covered with a fine somewhat brownish sand. The colour of the sand approximates that of the upper surface of the lobes, and these are practically level with the soil. This way it resist attacks from herbivorous predators, and is almost impossible to distinguish from their surroundings until they erupt into vivid daisy-like yellow flowers.Description: Lithops dinteri is a small succulent species characterised by pale green-grey-pink-brown faces scattered with bright blood-red dots embedded in surface of transparent window such as have not been observed, so far, in any other Lithops and the dots embedded in the tissue are level with it. It is however quite variable in colouration and the numbers of red dots on the tops of the leaves; varieties have been described but these, again, are of doubtful status: var. dinteri (with 10-15 red-dots) var. frederici (smaller with less marked dots), var. brevis (with only 3-5 red-dots) and var. multiptinctata (more coloured with dots often forming lines)
Habit: Growths solitary or few (2-3) in a clump to 3 cm high, but occasionally with more than 7 heads.
Bodies (paired leaves): Medium sized, 18-30 mm long, 13-20 mm broad, compact, turbinate-truncate. Sides coloured purplish green. Fissure 5-7 mm deep. Lobes elliptic-rectangular from above view, flat or slightly convex in profile, more or less equal, top of lobes, smooth, with a large transparent window and a few islands, seldom large, in which an abundance of tiny pale dots often agglomerated in nebulae can be observed; window completely open and translucent brown-green; in the window (5-)10–15(-more) very prominently coloured blood-red dots and/or short dashes and/or hooks (rubrications) distributed unevenly over the surface. (The cell walls in the red dots are coloured red); window bordered by a coloured band, outer part of which is light to dark yellow tinged with brown, this coloured margin more prominent and broader than the inner part of the border; in the margin at both ends where the fissure ends several dark-green to dark blue-green dots in the surface; inner margin practically straight and scarcely lobed or laciniated; outer margin with distinct with fairly regular shaped laciniae, some projecting into the window and forming islands, but islands usually absent or indistinct, opaque pale buff to yellowish, greenish or pinkish grey. Channels usually absent, various shades of translucent grey or grey-green, of-ten with a reddish tint.
Flowers: Daisy-like, diurnal, yellow, small to medium, up to 32 mm across, mostly 20-25 mm across.
Fruits: Capsules 4 or 5-chambered. Profile boat-shaped, top broadly elliptic, with hinge-rim flat, occasionaly slightly peaked.
Seeds: Very fine, brown, tuberculate.Lithops dinteri has leaves growing in pairs, and those pairs forming clumps of leaves. The leaves are thick, and hardly possess any stem. They have a small gap between them, out of which a yellow flower can blossom. The color of the sand or soil they grow in can determine the color of their lobes. Colors can range from red, to brown, to grey, and to cream. The leaves can also present red dots of the top, varying in number and size from plant to plant. The sides of the leaves are usually a purplish-green.
