Lithops karasmontana

Lithops karasmontana, is a species of flowering plant in the ice plant family Aizoaceae, native to Namibia and South Africa (the name refers to the Great Karas Mountains of Namibia).

Description

It is a clump-forming succulent growing to 4 cm (2 in) high and spreading. The almost stemless leaves appear in pairs, and resemble two grey stones with brown mottling on the flat surfaces. White, narrow-rayed flowers 3–4 cm (1–2 in) in diameter, appear in autumn. [2]

Lithops karasmontana resists attacks from herbivorous predators by mimicking the local stone formations, in this case quartzite. When not in flower it is extremely difficult to detect. [3]

L. karasmontana is generally treated as having two subspecies bella and eberlanzii, as well as ssp. karasmontana, [4] although one modern paper raises the two subspecies to species level on the basis of seed morphology. [5] Ssp. bella is distinguished by its relatively uniform appearance with beige colouring and darker windows. It often forms very large clumps with up to 60 heads. Ssp. eberlanzii is much more variable in appearance, with colours and markings similar to ssp. karasmontana, but it is generally smaller, softer, and more convex. [4]

Four varieties are also recognised: var. aiaisensis with creamy pinkish colouring, relative or complete lack of markings, and fairly smooth leaves; var. immaculata with almost unmarked beige leaves; [6] var. lericheana with wide channels and greenish colouring; and var. tischeri with convex leaf tops and reddish colouring. [4] Many older names are now sunk as synonyms in this highly variable species. [7]

Cultivation

In temperate regions it must be grown in heat under glass, in conditions similar to those for cactuses. Like all Lithops, it requires extremely well-drained soil.

Like all Lithops it also grows in annual cycles, as the leaf-pairs flower, and then each produces a new leaf-pair that replaces the old one (which shrivels away). The principal rule of watering is that Lithops should be kept dry from when they finish flowering, until the old leaf-pairs are fully replaced. It has gained the Royal Horticultural Society's Award of Garden Merit. [9] [10]

<i>Lithops</i> Genus of plants

Lithops is a genus of succulent plants in the ice plant family, Aizoaceae. Members of the genus are native to southern Africa. The name is derived from the Ancient Greek words λίθος 'stone' and ὄψ 'face', referring to the stone-like appearance of the plants. They avoid being eaten by blending in with surrounding rocks and are often known as pebble plants or living stones. Lithops is both the genus name and the common name. The formation of the name from the Ancient Greek -ops means that even a single plant is called a Lithops.

Lithops amicorum is a small succulent plant with white flowers, one of the smallest in the genus. It was named for the group of four friends who discovered it.

<span class="mw-page-title-main">Leaf window</span> Specialized leaf structure

Leaf window, also known as epidermal window, and fenestration, is a specialized leaf structure consisting of a translucent area through which light can enter the interior surfaces of the leaf where photosynthesis can occur. The translucent structure may include epidermal tissue, and in some succulent plants it consists of several cell layers of parenchyma, which may also function as water-storage tissue. It can appear as a large continuous patch, a variegated or reticulated region, or as numerous small spots. It is found in some succulent plants native to arid climates, allowing much of the plant to remain beneath the soil surface where it is protected from desiccation by winds and heat while optimizing light absorption. Many species featuring leaf windows are native to Southern Africa.

L. naureeniae was identified in 1980 by Desmond Cole, who became involved in Lithops research in 1947, from a specimen provided to him by Bruce Bayer, curator of the Karoo Botanic Garden, having been collected by Peter V. Bruyns in Namaqualand. It is named after Cole's wife, Naureen Cole. Cole wrote:

I therefore have pleasure in dedicating it to the person who, during the last fifteen years, directly and indirectly, has contributed more to research on and knowledge of the genus Lithops than any other—my wife, Naureen
