Flowers of Lithops lesliei subsp. lesliei, clearly no longer in their prime, can be seen in this photo. The fleshy oblong sepals with their pinkish, translucent tips are prominent. Some of the L. lesliei subsp. lesliei variations have white flowers. In full bloom, the petal whorls will open widely in the afternoon on sunny days. This show lasts until closing time at sunset in the flowering season, which is late autumn to early winter.
The plant in picture has only two leaf pairs, but the branched clumps may in time grow to ten of them; or just be one unbranched pair, producing its single flower per annum. The size of the leaf pair varies from 2 cm to 4 cm in diameter. The flower emerging from the central fissure between the fused leaves will just about cover the perimeter of the leaves when fully open (Smith, et al, 1998).
