During winter a new leaf pair, or occasionally more than one, grows inside the existing fused leaf pair. In spring the old leaf pair parts to reveal the new leaves and the old leaves will then dry up. Lithops leaves may shrink and disappear below ground level during drought. Yellow or white flowers emerge from the fissure between the leaves ...
The plant's leaves grow in pairs sometimes clumped together, however the leaves separate in the center and are widely divergent from one another, forming a large fissure between the leaves. [3] This is unlike the majority of its genus, for the leaves tend to grow next to one another without too much separation of most species.

Hedera helix adult leaves and unripe berries in Ayrshire, Scotland. On level ground ivies remain creeping, not exceeding 5–20 cm height, but on surfaces suitable for climbing, including trees, natural rock outcrops or man-made structures such as quarry rock faces or built masonry and wooden structures, they can climb to at least 30 m above the ground.
