Lithops karasmontana (Dint. & Schwant.) N.E. Br. (1920)


subsp. karasmontana


var. karasmontana



     
       

Origin:


Collected by Professor Kurt Dinter and his wife, Mrs Jutta Dinter, who discovered it in the Karas Mountains in October 1913.

Distribution:


Namibia, to the W and SW of the Great Karasberg, mainly in the areas around and betweem Klein Karas, Grünau and northwards, and Ai-Ais. TL Karas Mountains, without further detail, but apparently near Klein Karas.
Stone: Pegmatite; quartzite; gneiss; quartzite and calcrete; pegmatite, quartzite and sandstone. Colours grey-white, white, grey, pink, yellow-brown, brown, reddish brown, greenish white.

Description:


Extremely variable, some specimens being opaque and uniformly coloured, others with an extensive network of narrow channels and markings, and yet others with obscurely transluscent open windows; there is also a great deal of variation in the colours. In some colonies the plants tend to represent predominantly one colour or pattern form or another, but all colonies are 'mixed' in some degree, and in some all possible forms and intermediates occur.
Profile truncate; flat to slightly convex, occasionally slightly concave; fissure fairly deep, 4-10 mm; lobes conjunct.
Face flush, elliptic-reniform; lobes equal-unequal; mostly opaque; mostly somewhat rugose, occasionally smooth.
Margins usually obscure, occasionally fairly well-defined but irregular with numerous indentations.
Windows usually absent, the face then usually divided up by shallow valleys into a number of humps, but sometimes ± smooth and uniformly opaque; occasinally very obscurely transluscent, with or without shallow valleys.
Channels usually fairly narrow and irregular, occasionally a bold network, more often a number of dots, dashes or small triangular shapes set in shallow valleys, trenches or pits; sometimes reduced to narrow grooves, or to very slightly impressed obscure lines.
Islands sometimes absent; usually surrounded by narrow channels or grooves and then fairly clearly defined but irregular in shape; often obscure and manifest only as indistinct humps surrounded by equally obscure shallow valleys.
Rubrications sometimes absent, usually a number of short lines, hooks, triangles and dots which may be linked into a network; very often the channel areas are completely taken up by the rubrications, and they can be distinguished only under a lens.
Dusky dots seldom visible even with a lens.
Colours: Face, when entirely opaque, various shades of brick-red, beige, yellow, brown, pink, salmon, milky blue, grey-white. Margins and islands opaque light grey tinged with various shades of blue, green, yellow, brown, pink or red, or beige, sometimes with an obscure band of lighter colour around the margins. Windows (if apparent) and channels very obscurely transluscent grey, greyish, bluish or brownish green, greenish grey, greyish pink, brown or red-brown. Rubrications dark brown, red or purplish red. Dusky dots dull dark greyish green. Shoulders sometimes as for the margins, but lighter, otherwise bluish grey.
Size: Medium to large, facial diameters up to 35 X 28 mm, mostly about 25 X 20 mm. Number of heads up to 12 or more, mostly 2-6.

Flowers:


White, medium to large, up to 45 mm Ø, mostly 25-35 mm Ø.
Seed capsules mostly 5-merous (87%), otherwise 6-merous (11%), or 4-merous (2%). Profile boat-shaped, top ± flat. Face elliptic, up to 11 X 8 mm, mostly about 8 X 6,5 mm.
Seeds yellow-brown; smooth to rugose 1 to tuberculate 1, flecked.

Namibia, in a small area to the east of Ai-Ais, SW of Klein Karas. TL near Ai-Ais (C224).
Stone: Gneiss. Colours greyish white, grey, light brown.

Description:


Generally much less rugose and more uniform in colour than the type. This was originally published as a variety of *L. erniana, despite the contrary views of Dr A.L. Geyer. We agree with him that it is more closely related to and therefore more appropriately placed as a variety of subsp. karasmontana.
Profile truncate; flat to very slightly convex; fissure fairly deep, 6-10 mm; lobes conjunct.
Face flush, elliptic-reniform; lobes equal-unequal; mostly opaque; slightly rugose.
Margins often very indistinct and irregular.
Windows usually absent, occasionally faintly perceptible as very obscurely transluscent.
Channels usually rather obscure, mostly narrow and irregular, very slightly impressed, forming an indistinct broken network with faint lines tapering off into the margins.
Islands usually very indistinct and manifest as opaque areas or flecks between the shallow channels.
Rubrications often absent, otherwise a number of very obscure dots, hooks and/or short branched lines in the channels, often not distinguishable without a lens.
Dusky dots rarely visible even with a lens, sparse, mainly along the inner margins.
Colours: Face (margins and islands) opaque grey-white tinged with various shades of green, brown, buff, pink, mauve or cream, the margins sometimes banded obscurely in a slightly deeper or paler hue or suffused with a pale yellowish brown. Channels very obscurely transluscent grey, bluish or brownish grey, or grey-green. Rubrications dull brownish or purplish red. Dusky dots dull bluish grey-green. Shoulders as for the margins, or lighter, or pale bluish grey.
Size: Medium, facial diameters up to 32 X 23 mm, mostly about 27 X 20 mm. Number of heads up to 5 or more, mostly 2-3.

Flowers:


White, medium to large, up to 38 mm Ø, mostly 20-30 mm Ø.
Seed capsules mostly 5-merous (93%), otherwise 6-merous (5%), or 4-merous (2%). Profile boat-shaped, top ± flat. Face elliptic, up to 9,5 X 7 mm, mostly about 7,5 X 6 mm.

Distribution:


Namibia, at only one known locality, about 65 km NW of Karasburg (C182).
Stone: Brown, white and red-stained quartzite.

subsp. bella (N.E. Br) D.T. Cole (1922)



     

Origin:


Collected by Quartermaster Sergeant E.C. Phillips in 1920 or earlier; an attractive species appropriately named bella 'pretty, handsome' in Latin.

Distribution:


Namibia, in a narrow crescent area extending SSE from Aus to Witputs, and NNE towards Helmeringhausen. TL 'near Aus... on the top of small kopies (sic) in sandy gravelly soil' (C108). The report of this taxon occuring in the CP, 'at Jakhalswater, about 40 miles S. of Viool's Drift' (Bolus, Notes Mesem. 3:234 (Aug. 25, 1950)) is obviously based upon an incorrect identification; the plant collected there was no doubt a form of L. marmorata, which is common in that area.
Stone: Weathered granite; feldspathic granitic gneiss; pegmatite. Colours yellow-brown, brown, pink, grey-white, grey.

Description:


Distinguished from subsp. karasmontana by its colour and very distinct transluscent windows; uniform and easily identifiable.

Dusky dots rarely visible.
Colours: Margins and islands opaque, creamy buff, beige, yellow-grey or greenish grey, sometimes pinkish. Windows and channels dark pellucid green or grey-green, sometimes with a brown or greyish red tint. Rubrications dull red. Dusky dots dull greenish grey.

Lithops karasmontana (Dint. & Schwant.) N.E. Br. (1920)


subsp. eberlanzii (Dint. & Schwant.) D.T. Cole (1925)



     
 

Origin:


Collected by Friedrich G. Eberlanz in 1923 (?), and named for him. In 1922 plants of this subspecies were found to the south of Aus (Kuckaus-Pockenbank plains) by Professor Kurt Dinter, but he assumed them to be L. bella N.E. Br. Subsequently the plants from this area were published as *L. erniana Tisch. ex Jacobs.

Distribution:


Namibia, in a large quadrangular area based approximately on Lüderitz, Aus, Witputs and a point about 40 km SW of Witputs. TL 'in the Kovisberg', E of Lüderitz (C369). Our concept of subsp. eberlanzii includes *L. erniana Tisch. ex Jacobs.
Stone: Gneiss; biotitic gneiss and calcrete; pegmatite and calcrete: quartzite and calcrete; gneiss and calcrete; pegmatite; feldspar flecked with mica. Colours grey-white, white, light brown, brown, grey, pink, reddish brown; reddish pink flecked with black.

Description:


Extremely variable, occasional specimens being entirely opaque and almost uniform in colour, others with narrow to broad semi-transluscent channels, and yet others with a strong network of fine groove-like channels; there is also a great deal of variation in the colours.
Profile cordate-truncate; occasionally ± flat, usually distinctly convex; fissure fairly deep, 7-15 mm; lobes conjunct, sometimes slightly divergent at the top.
Face flush to slightly elevated; elliptic-reniform; lobes equal-unequal; mainly opaque; smooth to slightly rugose.
Margins usually not clearly distinguishable, with irregular indentations; occasionally fairly well-defined and regularly sinuate with bold peninsulas; often irregularly incised by few to many forked or branched lines extending and tapering out from the channels and forming small or large peninsulas.
Windows usually ± occluded, sometimes completely opaque with only very faint impressions of channels, rarely ± completely open.
Channels broad to narrow, occasionally fairly well-defined, usually rather indistinct and irregularly branched, the ends of the branches tapering off into the margins; often the channels are reduced to narrow slightly impressed grooves; the pattern of the branched channels was likened by Dr H.W. de Boer to the footprints of birds.
Islands sometimes bold and well-defined, often indistinct and fleck-like; sometimes no more than opaque slightly humped areas enclosed by channels; occasionally barely discernible against the background of opaque channels.
Rubrications sometimes absent; usually a network of slender branched lines set in the channels or grooves, very often reduced to a number of dots, hooks and/or short lines, which may be quite obscure and not visible without a lens.
Dusky dots not visible without a lens, very sparse and usually near the inner margins.
Colours: Face (margins and islands) various shades of opaque pale or dark grey-white, which may be tinted with blue, mauve, pink, brown, buff, beige, yellow or green; the margins occasionally obscurely banded in a slightly deeper shade. Windows and channels various shades of obscurely transluscent or opaque pale grey tinted with blue, green, pink, brown, mauve, buff, beige or dark grey-green. Rubrications red, brown, orange-brown, pink or purplish, sometimes bright and bold, often dull and rather indistinct. Dusky dots dull grey-green. Shoulders usually as for the face, but may be somewhat lighter or darker.
Size: Small to medium, facial diameters up to 38 X 25 mm, mostly about 25 X 20 mm. Number of heads up to 15 or more, mostly 2-4.

Flowers:


White, medium to large, up to 40 mm Ø, mostly 25-30 mm Ø.
Seed capsules mostly 5-merous (97%), otherwise mainly 6-merous (3%). Profile boat-shaped, top ± flat. Face round to broadly elliptic, up to 9 X 7 mm, mostly about 7 X 6 mm.
