Typical locality: The typical locality (TL) is an island (near) Keimoes, in the Orange River.
Habitat: Grows in stonily soils comprising Feldspathic quartzite; sheared pegmatite. Colours of the stony background greyish brown, pink, brown.

Description: Lithops bromfieldii var. insularis is one of the local form of the variable Lithops bromfieldiiSN|12915]]SN|12915]] , which grows in the immediate neighbourhood. It is a small sized plant characterised by bodies (significantly) smaller, darker, and more smooth, devoid of bumps, unless they are very thirsty. The colour of faces tends toward a deep earthy green, dark brown or black, with virtually no orange shine like in var. bromfieldii. The lines and the punctuation are dark and brilliant. The plants cluster profusely and form small cushions. However L. insularis is not a variant form of L. Bromfieldii and it stands at the one end of the breadth of variation of L. Bromfieldii and that L. Bromfieldii, as described by L. Bolus, is at the other end. This can only be settled by an examination of these two species in their natural habitat and cultivated plants can be reliably distinguished from Lithops bromfieldiiSN|12915]]SN|12915]] only when seeds or details of wild source are available.
Habit: Lithops bromfieldiiSN|12915]]SN|12915]] var. insularis forms clumps or cushions of 10 or more heads, up to to 1,5 cm high and conforms to the typical Lithops morphology: two thick, fleshy windowed leaves separated by a crack from which a yellow flower appears. The windowed part allows light into the inner portion of the leaf where the process of photosynthesis is carried out. As with many other species, several varieties or local forms have been described based on the variation of the colour of the tops of the leaves.
Bodies (paired leaves): Mostly less than 20 mm wide, obconical, truncate darker, and more smooth than the type, devoid of bumps, unless they are very thirsty. The colour of faces tends toward a deep earthy green, dark brown or black, with virtually no orange shine like in var. bromfieldii. The lines and the punctuation are dark and brilliant. The margins with small irregular peninsula are quite indistinct. Rubrications dull blood-red.
Flowers: Yellow, thinly petaled, 25-35 mm in diameter.
Fruits: Mostly 5-chambered, profile boat-shaped, top flat.
Seeds: Yellow-brown, rugose.
