Lithops divergens L. Bol (1934)


var. divergens



   

Origin:


Collected by Mrs Aletta Helena Eksteen in December 1933 (NBG 2295/33). Latin divergens 'diverging', in reference to the lobes.

Distribution:


RSA: CP, in a relatively narrow strip between Vanrhynsdorp and Garies, mainly in the Knersvlakte. TL '30 miles N of Vanrhynsdorp' (C202).
Stone: White quartzite, with some brown, red and black.

Description:


Distinguished by its pale grey-green colour and 'frosted glass' appearance; very uniform and easily identifiable.
Profile bicuneate; top surface usually somewhat convex; fissure deep, 7-12 mm, usually wider and deeper on one side than the other, thus producing a lopsided effect; lobes usually distinctly divergent.
Face flush to slightly elevated; mostly elongated elliptic; lobes equal-unequal; opaque + transluscent; smooth.
Margins very slender lines, usually regular.
Windows occasionally almost completely opaque, usually extensively occluded by a fine mottling of very small fleck-like islands, producing the effect of cobweb or frosted glass.
Channels very narrow, irregular, indistinct.
Islands rather indistinct, small, numerous, finely mottled flecks investing the whole window.
Rubrications absent.
Dusky dots seldom visible, even with a lens.
Colours: Margins and islands various shades of opaque pale greenish, bluish, pinkish or milky grey. Channels various shades of transluscent pale greyish green. Shoulders greenish or pinkish grey. Faces of fissures as for the shoulders.
Size: Very small to small, facial diameters up to 25 X 14 mm, mostly about 20 X 12 mm. Number of heads up to 10 or more, mostly 2-4.

Flowers:


Yellow with white centre, very small to medium, up to 27 mm Ø, mostly 15-20 mm Ø.
Seed capsules mostly 5-merous (96%), otherwise 6-merous (3%). Profile boat-shaped, top flat. Face round to broadly elliptic, with hinge-rim, up to 5,5 X 5,5 mm, mostly about 4,5 X 4,5 mm.
Seeds light brown to brown, tuberculate 2, brown.

Lithops divergens L. Bol (1934)


var. amethystina H.W. de Boer (1961)



     

Origin:


Collector not named; probably Dr A.L. Geyer. Latin 'amethystina' coloured amethyst or violet.

Distribution:


RSA: CP, in a relatively narrow strip extending eastwards from Kliprand. TL not specified; by inference 'Nuwe Fontein', i.e. Kliprand (C270)
Stone: Shale with calcrete and quartzite. Colours yellow-brown, grey-white, grey, brown, black.

Description:


Similar to the type, but larger, generally with more open windows, and ofteen tinged with pink or amethyst.
Profile bicuneate; top surface convex, often ± humped and slightly lobsided; fissure deep, 10-20 mm, sometimes more widely open and deeper on one side than the other; lobes usually distinctly divergent.
Face somewhat elevated; mostly elongated elliptic; lobes equal-unequal; opaque + transluscent; smooth to slightly rugse.
Margins very slender lines, usually regular, occasionally slightly dentate; usually extended downwards at each end along the outer edges of the fissures and drawn to fine points.
Windows usually ± completely open, sometimes finely mottled.
Channels very narrow, irregular, indistinct.
Islands small, few to many, indistinct, in the form of faint fine mottling, sometimes resembling cobweb or slightly frosted glass.
Rubrications absent.
Dusky dots seldom visible, even with a lens.
Colours: Margins and islands various shades of opaque pale greenish, creamy or pinkish (amethyst) grey. Windows and channels various shades of transluscent pale greyish or bluish green or faintly pinkish grey, the more open windows often having a distinctly glassy appearance. Dusky dots dull greyish blue. Shoulders various shades of opaque pinkish (amethyst) or greenish grey, or greyish pink or green. Faces of fissures as for the shoulders.
Size: Small to medium, facial diameters up to 35 X 20 mm, mostly about 23 X 13 mm. Number of heads up to 7 or more, mostly 2-4.

Flowers:


Yellow with white centre, very small to medium, up to 35 mm Ø, mostly 20-30 mm Ø.
Seed capsules mostly 5-merous (98%), otherwise 4- or 6-merous (2%). Profile boat-shaped, top flat. Face broadly elliptic to round, with hinge-rim, up to 9 X 7,5 mm, mostly about 6,5 X 6 mm.
Seeds dark brown, tuberculate 2.
