Lithops verruculosa G.C. Nel (1943)


var. verruculosa



       

Origin:


Collected Dr ?? van der Westhuizen in September 1939. Latin verruculosa 'having verruculae or warts'.

Distribution:


RSA: CP, in a very large roughly quadrangular area based on Kenhardt, a point S of Prieska, Brandvlei, and a point E of Gamoep. TL 'North West Cape', without further detail.
Stone: Amygdaloidal lavas and banded ironstone with some calcrete; calcrete with fine-grained quartzitic sandstones; calcrete with cherts and jaspers; calcrete with cherts and fine-grained sandstone; calcrete with shaly sandstones; calcrete in granitic soil. Colours grey-white, grey, brown, reddish brown, greyish green, some pink, red, black, blue.

Description:


Distinguished by the conspicuous small red verruculae or pimples on the face, and its wide range of flower colours, neither of which features occurs in any other species.
Profile truncate; top surface flat to slightly convex, occasionally slightly concave; fissure shallow, 4-8 mm; lobes conjunct.
Face flush, usually distinctly reniform; lobes equal-unequal; opaque to transluscent; almost smooth to somewhat rugose.
Margins fairly well-defined in open-windowed specimens, but irregularly dentate with small peninsulas and numerous lines, simple and forked, extending out from the windows; otherwise not clearly distinguishable.
Windows usually ± occluded, occasionally ± completely open, often reduced to very narrow channels; in all cases, usually with fine lines tapering off into the margins.
Channels broad to narrow, slightly impressed, irregular; often reduced to an irregular network of slightly impressed fine grooves.
Islands distinct or manifest as areas ± enclosed by the grooves; few to many, small to large, mostly somewhat irregular, usually well-defined but sometimes reduced to indistinct flecks.
Rubrications usually conspicuous and numerous, small to very small warts or pimples, up to 1 mm Ø, usually round and ± isolated from one another; sometimes closely contiguous and forming short dashes, commas or tadpole shapes; usually situated in the channels, almost always slightly raised, occasionally ± flush with the bottom of the channel and then less conspicuous.
Dusky dots not visible.
Colours: Face (margins and islands) various shades of opaque grey or beige tinged with pink, yellow, light brown, lilac, green or blue. Windows & channels various shades of transluscent greyish, brownish or reddish green, or greenish brown or bluish or greenish grey. Rubrications dark blood-red or purplish red, usually clear and slightly shiny, sometimes deeper set, covered with a bluish film, and then obscurely bluish red. Shoulders various shades of opaque bluish grey or greyish blue, sometimes contrasting quite strikingly with the margins.
Size: Medium to large, facial diameters up to 34 X 26 mm, mostly about 25 X 18 mm. Number of heads up to 8 or more, mostly 2-4.

Flowers:


Extremely variable in colour, mostly shades of straw yellow, but also ranging from golden yellow through dark yellow, light orange, bronze, carrot and lime yellow, shell-pink and rose, salmon, cream and near-white; often with a contrasting tint or inner ring of orange, rose-pink, mauve or magenta, which may extend up onto the stamens; small to medium, up to 35 mm Ø, mostly 20-25 mm Ø.
Seed capsules mostly 5-merous (90%), otherwise mainly 6-merous (6%), 4-merous (2%) or 7-merous (1%). Profile boat-shaped, top flat. Face elliptic to almost round, up to 8 X 7 mm, mostly about 6,5 X 5 mm.
Seeds yellow-brown, smooth to rugose 1 to tuberculate 2, flecked.

Lithops verruculosa G.C. Nel (1943)


var. glabra H.W. de Boer (1966)



   

Origin:


Collected by Dr Geoffrey R. McLachlan in 1962, and by Victor L. Pringle and A.A. Roux in May 1963. Latin glabra 'smooth', i.e. (mostly) without raised islands or small warts.

Distribution:


RSA: CP, in a small area to the S, SE and E of Kenhardt. TL 'to the south of Kenhardt' (C160).
Stone: Pegmatite; pegmatite and calcrete. Colours grey-white, pink, grey, brown.

Description:


Similar to var. verruculosa but generally more grey in colour, the verruculae occasionally absent or otherwise fewer, smaller and less conspicuous.
Profile truncate; top surface flat to slightly convex, occasionally slightly concave; fissure shallow, 5-8 mm; lobes conjunct.
Face flush; usually distinctly reniform; lobes equal-unequal; mostly opaque, occasionally obscurely transluscent; smooth to minutely rugose.
Margins usually distinct, slightly dentate or sinuate, with some peninsulas.
Windows often ± occluded, sometimes ± completely open, often with numerous fine lines tapering off into the margins.
Channels broad to narrow, irregular, occasionally reduced to a network of slightly impressed slender grooves.
Islands few to many, small to large, mostly fairly regular, usually distinct but sometimes reduced to obscure flecks.
Rubrications occasionally absent, usually relatively fewer and smaller than in var. verruculosa, and often covered with a bluish film which makes them relatively inconspicuous.
Dusky dots not visible without a lens, obscure, few to many, scattered in the channels.
Colours: Face (margins and islands) various shades of opaque pale milky grey or cream, sometimes tinged with pink or blue. Windows & channels opaque to obscurely transluscent light grey, pale pinkish, bluish or greenish grey, or greyish green or lilac. Rubrications dark red, or dull red underlying a bluish film. Shoulders various shades of pale grey, often tinged with blue..
Size: Small to medium, facial diameters up to 30 X 20 mm, mostly about 23 X 17 mm. Number of heads up to 8 or more, mostly 2-4.

Flowers:


Extremely variable in colour, as for var. verruculosa, small to medium, up to 32 mm Ø, mostly 20-25 mm Ø.
Seed capsules mostly 5-merous (91%), otherwise mainly 6-merous (7%), 7-merous (1%) or 4-merous (1%). Profile boat-shaped, top ± flat. Face broadly elliptic, up to 7,5 X 6,5 mm, mostly about 7 X 5,5 mm.
Seeds yellow-brown, tuberculate 1, flecked brown.
