They avoid being eaten by herbivores with <a href="Camouflage_in_plants" class="mw-redirect" title="Camouflage in plants">their camouflage</a> as small stones, and are often known as <b>pebble plants</b> or <b>living stones</b>.
</p><p>"Lithops" is both the genus name and the common name, and is singular as well as plural. The name is derived from the <a href="Ancient_Greek" title="Ancient Greek">Ancient Greek</a> words <span lang="grc"><a href="https://en.wiktionary.org/wiki/%CE%BB%CE%AF%CE%B8%CE%BF%CF%82#Ancient_Greek" class="extiw external" title="wikt:λίθος">λίθος</a></span> (<span title="Ancient Greek (to 1453)-language romanization"><i lang="grc-Latn">líthos</i></span>) 'stone' and <span lang="grc"><a href="https://en.wiktionary.org/wiki/%E1%BD%84%CF%88#Ancient_Greek" class="extiw external" title="wikt:ὄψ">ὄψ</a></span> (<span title="Ancient Greek (to 1453)-language romanization"><i lang="grc-Latn">óps</i></span>) 'face', referring to the stone-like appearance of the plants.

<div class="mw-heading mw-heading2"><h2 id="Description">Description</h2></div>

<p>Individual <i>Lithops</i> consist of one or more pairs of bulbous, almost fused <a href="Leaf" title="Leaf">leaves</a> opposite each other and hardly any <a href="Plant_stem" title="Plant stem">stem</a>. The slit between the leaves contains the <a href="Meristem" title="Meristem">meristem</a> and produces <a href="Flower" title="Flower">flowers</a> and new leaves. The leaves of <i>Lithops</i> are mostly buried below the surface of the <a href="Soil" title="Soil">soil</a>, with a partially or completely translucent top surface known as a <a href="Leaf_window" title="Leaf window">leaf window</a> which allows light to enter the interior of the leaves for <a href="Photosynthesis" title="Photosynthesis">photosynthesis</a>.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">[</span>2<span class="cite-bracket">]</span></a></sup>
</p><p>During winter a new leaf pair, or occasionally more than one, grows inside the existing fused leaf pair. In <a href="Spring_(season)" title="Spring (season)">spring</a> the old leaf pair parts to reveal the new leaves and the old leaves will then dry up. <i>Lithops</i> leaves may shrink and disappear below ground level during <a href="Drought" title="Drought">drought</a>. Yellow or white flowers emerge from the fissure between the leaves after the new leaf pair fully matures, one per leaf pair. This is usually in autumn, but can be before the summer <a href="Solstice" title="Solstice">solstice</a> in <i><a href="Lithops_pseudotruncatella" title="Lithops pseudotruncatella">L. pseudotruncatella</a></i> and after the winter <a href="Solstice" title="Solstice">solstice</a> in <i><a href="Lithops_optica" title="Lithops optica">L. optica</a></i>. The flowers are often sweetly scented.
</p>

<p>The most startling <a href="Adaptation" title="Adaptation">adaptation</a> of <i>Lithops</i> is the colouring of the leaves. The leaves are <a href="Leaf_window" title="Leaf window">fenestrated</a>, and the <a href="Leaf_window" title="Leaf window">epidermal windows</a> are patterned in various shades of cream, grey, and brown, with darker windowed areas, dots, and red lines, according to species and local conditions. The markings function as remarkable <a href="Camouflage_in_plants" class="mw-redirect" title="Camouflage in plants">camouflage for the plant</a> in its typically stony environment. As is typical of a window plant, the green tissue lines the inside of the leaves and is covered with <a href="Transparency_and_translucency" title="Transparency and translucency">translucent</a> tissue beneath the epidermal windows.
</p><p><i>Lithops</i> are obligate <a href="Outcrossing" title="Outcrossing">outcrossers</a> and require <a href="Pollination" title="Pollination">pollination</a> from a separate plant. Like most <a href="Mesemb" class="mw-redirect" title="Mesemb">mesembs</a>, Lithops fruit is a dry <a href="Capsule_(fruit)" title="Capsule (fruit)">capsule</a> that opens when it becomes wet; some <a href="Seed" title="Seed">seeds</a> may be ejected by falling raindrops, and the capsule re-closes when it dries out. Capsules may also sometimes detach and be distributed intact, or may disintegrate after several years.
</p>
<div class="mw-heading mw-heading2"><h2 id="Distribution">Distribution</h2></div>

<p><i>Lithops</i> occur naturally across wide areas of <a href="Namibia" title="Namibia">Namibia</a> and <a href="South_Africa" title="South Africa">South Africa</a>, as well as small bordering areas in <a href="Botswana" title="Botswana">Botswana</a> and possibly <a href="Angola" title="Angola">Angola</a>, from sea level to high mountains. Nearly a thousand individual populations are documented, each covering just a small area of dry grassland, <a href="Veld" title="Veld">veld</a>, or bare rocky ground. Different <i>Lithops</i> species are preferentially found in particular environments, usually restricted to a particular type of rock. <i>Lithops</i> have not <a href="Naturalisation_(biology)" title="Naturalisation (biology)">naturalised</a> outside this region.
</p><p><a href="Rain" title="Rain">Rainfall</a> in <i>Lithops</i> habitats ranges from approximately 700&nbsp;mm/year to near zero. Rainfall patterns range from exclusively summer rain to exclusively winter rain, with a few species relying almost entirely on dew formation for moisture. Temperatures are usually hot in summer and cool to cold in winter, but one species is found right at the coast with very moderate temperatures year round.
</p>
<div class="mw-heading mw-heading2"><h2 id="Cultivation">Cultivation</h2></div>

<p><i>Lithops</i> are popular <a href="House_plant" class="mw-redirect" title="House plant">house plants</a> and many specialist <a href="Succulent" class="mw-redirect" title="Succulent">succulent</a> growers maintain collections. <a href="Seed" title="Seed">Seeds</a> and plants are widely available in shops and over the <a href="Internet" title="Internet">Internet</a>. They are relatively easy to grow and care for if given sufficient sun and kept in well-draining soil.
</p><p>Normal treatment in mild <a href="Temperateness" class="mw-redirect" title="Temperateness">temperate</a> <a href="Climate" title="Climate">climates</a> is to keep them completely dry during winter, watering only when the old leaves have dried up and are replaced by a new leaf pair. Watering continues through autumn, when the plants flower, and then stops for winter. The best results are obtained in an environment with additional heat such as a greenhouse. In hotter <a href="Climate" title="Climate">climates</a>, <i>Lithops</i> will have a summer dormancy when they should be kept mostly dry, and they may require some water in winter. In <a href="Tropical_climate" title="Tropical climate">tropical</a> climates, <i>Lithops</i> can be grown primarily in winter with a long summer dormancy. In all conditions, <i>Lithops</i> will be most active and need most water during autumn and most species will flower at approximately the same time.
</p>

<p><i>Lithops</i> thrive best in a coarse, well-drained substrate. Any soil that retains too much water will cause the plants to burst their skins as they over-expand. Plants grown in strong light will develop hard strongly coloured skins which are resistant to damage and rot, although persistent overwatering will still be fatal. Excessive heat will kill potted plants as they cannot cool themselves by <a href="Transpiration" title="Transpiration">transpiration</a> and rely on staying buried in cool soil below the surface. Commercial growers mix a mild fungicide or weak strength horticultural sulfur into the plant's water to prevent rotting. Lithops are sensitive to watering during hot weather, which can cause the plants to rot; in habitat the plants are often dormant when the temperatures are high, doing most of their growing during the cool months of the year. Low light levels will make the plants highly susceptible to rotting and fungal infection.<sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">[</span>3<span class="cite-bracket">]</span></a></sup>

<p>Mr Keith Green was appointed <a href="International_Cultivar_Registration_Authority" title="International Cultivar Registration Authority">International Cultivar Registration Authority</a> for <i>Lithops</i> in 2013, and recognises over 100 registered <a href="Cultivar" title="Cultivar">cultivars</a>.<sup id="cite_ref-scrapbook_10-0" class="reference"><a href="#cite_note-scrapbook-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup>
</p><p>Since <i>Lithops</i> are mostly propagated by seed, cultivars require to be stabilised as seed strains. Most cultivars are either abnormally green or abnormally red plants, lacking most of the normal leaf pigments. Some were initially found as isolated unusual plants in habitat, but increasingly have arisen from cultivation, sometimes by deliberately selecting mildly-coloured plants to achieve intense colours for a cultivar. The term "aberrant colour form" (acf.) has been used for these unusually-coloured <i>Lithops</i>.<sup id="cite_ref-cole2006_11-0" class="reference"><a href="#cite_note-cole2006-11"><span class="cite-bracket">[</span>11<span class="cite-bracket">]</span></a></sup>
</p><p>There are also so-called "pattern cultivars" of <i>Lithops</i>, seed strains which have been selectively-bred or stabilised from isolated unusual plants to have intensified or unusual leaf patterns, and sometimes unusual flowers. In some cases, these are <a href="Hybrid_(biology)" title="Hybrid (biology)">hybrids</a>.<sup id="cite_ref-scrapbook_10-1" class="reference"><a href="#cite_note-scrapbook-10"><span class="cite-bracket">[</span>10<span class="cite-bracket">]</span></a></sup>
</p>
<div class="mw-heading mw-heading3"><h3 id="Propagation">Propagation</h3></div>

<p>Propagation of <i>Lithops</i> is by <a href="Seed" title="Seed">seed</a> or <a href="Cutting_(plant)" title="Cutting (plant)">cuttings</a>. Cuttings can only be used to produce new plants after a plant has naturally divided to form multiple heads, so most propagation is by seed. <i>Lithops</i> can readily be pollinated by hand if two separate <a href="Cloning" title="Cloning">clones</a> of a species flower at the same time, and seed will be <a href="Ripening" title="Ripening">ripe</a> about 9 months later. Seed is easy to <a href="Germinate" class="mw-redirect" title="Germinate">germinate</a>, but the seedlings are small and vulnerable for the first year or two, and will not flower until at least two or three years old.

<div class="mw-heading mw-heading2"><h2 id="History">History</h2></div>

<p>The first scientific description of <i>Lithops</i> was made by <a href="Botanist" class="mw-redirect" title="Botanist">botanist</a> and artist <a href="William_John_Burchell" title="William John Burchell">William John Burchell</a>, explorer of <a href="South_Africa" title="South Africa">South Africa</a>, although he called it <i><a href="Mesembryanthemum" title="Mesembryanthemum">Mesembryanthemum</a> turbiniforme</i>. In 1811, Burchell discovered a specimen when picking up a "curiously shaped pebble" from the ground.<sup id="cite_ref-cole2006_11-1" class="reference"><a href="#cite_note-cole2006-11"><span class="cite-bracket">[</span>11<span class="cite-bracket">]</span></a></sup> Unfortunately the documented physical description was not detailed enough to be sure which <i>Lithops</i> he had discovered and the name <i>Lithops turbiniformis</i> is no longer used, although for many years it was applied to what is now known as <i><a href="Lithops_hookeri" title="Lithops hookeri">Lithops hookeri</a></i>.
</p><p>Several more <i>Lithops</i> were published as <i>Mesembryanthemum</i> <a href="Species" title="Species">species</a> until in 1922 <a href="Nicholas_Edward_Brown" class="mw-redirect" title="Nicholas Edward Brown">N E Brown</a> started to split up the overly large genus on the basis of the <a href="Capsule_(fruit)" title="Capsule (fruit)">capsules</a>. The <a href="Genus" title="Genus">genus</a> <i>Lithops</i> was created and dozens more species were published in the following decades. Brown, <a href="Martin_Heinrich_Gustav_Schwantes" title="Martin Heinrich Gustav Schwantes">Gustav Schwantes</a>, <a href="Kurt_Dinter" title="Kurt Dinter">Kurt Dinter</a>, <a href="Gert_Nel" class="mw-redirect" title="Gert Nel">Gert Nel</a>, and Louisa Bolus continued to document <i>Lithops</i> from across southern Africa, but there was little consensus on the relationships between them, or even which populations should be grouped as species. As recently as the 1950s, the genus remained rather unknown in cultivation and was not well understood <a href="Taxonomically" class="mw-redirect" title="Taxonomically">taxonomically</a>.
</p><p>In the 1950s, Desmond and Naureen Cole began to study <i>Lithops</i>. Together, the couple visited nearly all natural habitats of the different lithops populations and collected samples from approximately 400. They document and identify them, assigning a number, which is now known as the Cole number still used today all around the world. They studied and revised the genus, in 1988 publishing a definitive book <i>(Lithops: Flowering Stones</i>) describing the <a href="Species" title="Species">species</a>, <a href="Subspecies" title="Subspecies">subspecies</a>, and <a href="Variety_(botany)" title="Variety (botany)">varieties</a> which have been accepted ever since.
</p><p>Because their camouflage is so effective, new species continue to be discovered. Recent discoveries include <i><a href="Lithops_coleorum" title="Lithops coleorum">L. coleorum</a></i> in 1994, <i><a href="Lithops_hermetica" title="Lithops hermetica">L. hermetica</a></i> in 2000, and <i><a href="Lithops_amicorum" title="Lithops amicorum">L. amicorum</a></i> in 2006.<sup id="cite_ref-13" class="reference"><a href="#cite_note-13"><span class="cite-bracket">[</span>13<span class="cite-bracket">]</span></a></sup>
