Leslie's living stone

Lithops lesliei

Also calledBeeskloutjie ('cattle hoof', Afrikaans) · Klipblom ('stone flower', Afrikaans) · Living stone (English) · Pebble plant (English) · 生石花 shēngshíhuā (Chinese)

A plant disguised as a pebble. Each Lithops is just a pair of fat, fused leaves sunk in the ground, with only patterned 'windows' at the top showing. Light enters through these windows and lights up the inside of the leaf, letting it photosynthesise while staying mostly buried.

Lithops lesliei is a species of plant in the family Aizoaceae. The plant is collected for its medicinal properties, and has therefore become threatened. Wikipedia

§1

What it can do

  1. iCamouflages as stones, with colours that match the local rock
  2. iiLets light into the leaf through translucent 'windows' on top while the rest of the body stays below ground
  3. iiiEach year grows a new pair of leaves inside the old, which then shrivels and is absorbed
  4. ivIts seed capsules open only when wet, so raindrops splash seeds out

Fruit & seed

Fruit

Hygrochastic capsule

Ripens: After autumn flowering

Small capsules that open when wet and close as they dry.

Seed

~0.5 mm

Dust-like brown seeds

Dispersal
Raindrop splash
Germination
Surface-sow on gritty mix, keep humid at 15–25 °C; 1–3 weeks

USDA 10–11 (or sunny windowsill). Survives winters down to about -1 °C.

Light
Full sun to very bright light
Water
Very low; water in summer and autumn growth, none while old leaves are being absorbed
Soil
Mostly mineral grit (pumice, sand) with a little compost
Propagation
Seed, rarely division
To harvest
Flowers (yellow daisies) after 3–4 years
Climates
Arid, Semi-arid
  1. 1Surface-sow seed on fine grit and cover to hold humidity
  2. 2Gradually reduce humidity as seedlings grow
  3. 3Water during summer–autumn growth; stop while new leaves are emerging
  4. 4Overwatering is the main cause of death: the old leaves split and rot

Where it lives

Recorded sightings

—

geo-referenced records in GBIF, from museums, herbaria and field observers.

Native range

Grasslands and rocky outcrops of northern South Africa (Gauteng, North West, Free State, Limpopo, Northern Cape) and edges of Botswana

Drag the globe to turn it. Dots are where records exist, not a range map; darker means more records.

In the old herbals & bestiaries

No plate in the Source Library names this exact species, so these show its closest relatives as the old naturalists drew them: same genus, or the same kind of plant. Click a plate to read the page it came from, with translation.

§8

Marginalia

Named after Thomas Leslie, an amateur botanist who collected it near Pietersburg (now Polokwane) in 1912. Afrikaans farmers called Lithops 'beeskloutjies' because their split shape looks like a cow's hoof print.

Curiosity

Lithops are so well hidden that many species were found only when the plants were flowering.
