"Haworthia cooperi is a slow-growing succulent that forms clumps of stemless or short-stemmed rosettes of light green leaves with darker longitudinal lines and transparent tips. The rosettes can reach up to 3.2 inches (8 cm) in diameter. The leaves have a flat or slightly convex upper surface, a convex lower surface keeled upwards, and margins and keel usually armed with pellucid teeth.

The specific epithet "cooperi (koo-PER-ee)" honors Thomas Cooper (1815-1913), an English botanist and explorer who collected plants in South Africa from 1859 to 1862.

The very small flowers (about 3mm or 1/8") are white to pinkish-white with green to brown veins and appear on stalks." World of Succulents
