Description:


Characterized mainly by its greenish-grey or greyish-green range of colours and its distinct margins and mostly open windows.
Profile truncate-cordate; top surface flat to somewhat convex; fissure fairly deep, 7-13 mm; lobes conjunct or very slightly divergent.
Face flush, elliptic-reniform; lobes equal-unequal; opaque + obscurely transluscent; smooth to slightly rugose.
Margins distinct, occasionally fairly regular, usually irregularly dentate or sinuate with some peninsulas.
Windows occasionally partly occluded, mostly ± completely open.
Channels usually fairly broad, irregular.
Islands usually few and fairly small, mostly distinct, occasionally reduced to hazy flecks.
Rubrications absent.
Dusky dots rarely visible even with a lens, very obscure.
Colours: Margins & islands various shades of opaque greenish, pinkish, brownish or creamy grey, or greyish green. Windows & channels various shades of opaque or obscurely transluscent greenish grey or greyish, bluish, pinkish or brownish green. Dusky dots very obscure dull dark grey-green. Shoulders as for the margins but duller and greyer, or various shades of opaque bluish grey.
Size: Small to medium, facial diameters up to 32 X 25 mm, mostly about 23 X 18 mm. Number of heads up to 8 or more, mostly 2-4.

Flowers:


White, small to medium, up to 30 mm Ø, mostly 20-25 mm Ø.
Seed capsules mostly 6-merous (84%), otherwise 5-merous (8%) and 4-merous (8%). Profile boat-shaped, top ± flat. Face broadly elliptic, up to 9 X 7 mm, mostly about 8 X 6,5 mm; the cell-lids often slightly ribbed or wrinkled transversely.
Seeds yellow-brown to light brown, smooth to rugose 1, flecked.

Lithops villetii L. Bol. (1950)


subsp. deboeri (Schwant.) D.T. Cole (1952)



     

Origin:


Collector of original specimens unknown, probably Professor G.C. Nel in 1947 or thereabouts. Collected by D.T. & N.A. Cole on 6 September 1971. Named for Dr Hindrik Wijbrand de Boer of Haren, Holland, who made unrivalled contributions to the study of Lithops during the years 1945-70..

Distribution:


RSA: CP, in a small area extending NW and E from Kalkstasie (E of Gamoep), and some 40 km N of the range of subsp. villetii, and W of the range of subsp. kennedyi. TL unknown; it was probably E of Kalkstasie, somewhere near C230. The TL 'Stafvlei' (sic) cited by B. Fearn has no factual basis.
Stone: Calcrete with some quartzite; calcrete with some sandstone and quartzite; shale and sandstone. Colours pinkish grey-white with some brown, grey; pinkish brown with some red, black, grey.

Description:


Distinguished from the type by its generally more bluish or reddish-grey colours, more irregular margins, more occluded windows and more numerous islands; rather distinctive, uniform, and usually fairly easy to identify.
Profile truncate-cordate; top surface ± flat to somewhat convex; fissure shallow, 5-10 mm; lobes conjunct, occasionally slightly divergent.
Face flush, elliptic-reniform; lobes equal-unequal; mostly opaque; slightly rugose.
Margins usually distinct but very irregularly dentate or sinuate with numerous peninsulas.
Windows usually ± occluded.
Channels usually fairly narrow, irregular, often tapering off into the margins as fine forked lines; occasionally reduced to narrow grooves.
Islands usually numerous, mostly fairly small, usually distinct but irregular, occasionally reduced to hazy flecks.
Rubrications absent.
Dusky dots very rarely visible even with a lens, very obscure.
Colours: Margins & islands various shades of opaque bluish, greenish, pinkish or reddish grey, the colour of the islands often more intense or browner. Windows & channels various shades of opaque or obscurely transluscent bluish, greenish, pinkish, reddish or purplish grey. Dusky dots dull dark greenish grey. Shoulders various shades of opaque grey or bluish, greenish or pinkish grey, the colour sometimes extending also over onto the peninsulas and outer islands.
Size: Small to medium, facial diameters up to 34 X 24 mm, mostly about 23 X 17 mm. Number of heads up to 7 or more, mostly 2-3.

Flowers:


White, small to medium, up to 30 mm Ø, mostly 20-25 mm Ø.
Seed capsules mostly 6-merous (97%), otherwise 5-merous (2%) or 7-merous (1%). Profile boat-shaped, top ± flat. Face broadly elliptic to almost round, up to 8 X 6 mm, mostly about 7,5 X 6 mm; the cell-lids often slightly ribbed or wrinkled transversely.
Seeds yellow-brown, rugose 1, flecked.

Lithops villetii L. Bol. (1950)


subsp. kennedyi (H.W. de Boer) D.T. Cole (1967)



       

Origin:


Collected by Hermias Cornelis (Mias) Kennedy in 1966 and named for him.

Distribution:


RSA: CP, in a relatively small area between Pofadder and Loeriesfontein and E of Gamoep, E of the range of subsp. deboeri, and some 40 km N of the range of subsp. villetii. TL 'Bushmanland, 30 miles N of Buchufontein' (C123). The plants at the TL grow in pinkish grey-white calcrete and are generally smaller and greyer in colour than the mainly reddish-brown forms occuring in all other localities; they are therefore the least characteristic of the subspecies.
Stone: Fine-grained sandstone; silty sandstone; sandstone with some pegmatite; sandstone with some calcrete; calcrete with some sandstone. Colours brown, reddish brown, greyish brown, with some grey, pink, black, white; pinkish grey-white with some grey, dark brown, black.

Description:


Distinguished by its truncate profile, narrow and much indented margins and generally reddish-brown colour; uniform and usually easily identifiable.
Profile truncate; top surface mostly ± flat; fissure shallow, 6-10 mm; lobes conjunct, occasionally very slightly divergent.
Face flush, elliptic-reniform; lobes equal-unequal; opaque; slightly rugose.
Margins distinct, irregularly and extensively dentate, infrequently with small peninsulas.
Windows usually ± occluded, infrequently ± completely open.
Channels mostly fairly narrow, irregular.
Islands few to many, usually numerous, mostly small, usually distinct but often reduced to obscure flecks.
Rubrications absent; the reddish lining sometimes seen in the margins superficially appears to be, but is not a series of rubrications.
Dusky dots not visible.
Colours: Margins and islands various shades of opaque grey, bluish or pinkish grey, or greyish pink, brown, orange-brown or red; the margins, especially in the indentations, often thinly lined with a more intense brownish or reddish suffusion, which also occurs sometimes around the islands. Windows & channels various shades of opaque greenish or brownish grey or greyish green, brown, orange-brown or purplish brown. Shoulders sometimes as for the margins, but often more grey or bluish grey; sometimes this colour extends also onto the peninsulas and outer islands.
Size: Medium to large, facial diameters up to 36 X 25 mm, mostly about 28 X 20 mm. Number of heads up to 4 or more, mostly 2.

Flowers:


White, small to medium, up to 30 mm Ø, mostly 20-25 mm Ø.
Seed capsules mostly 6-merous (88%), otherwise mainly 7-merous (9%) or 5-merous (2%). Profile boat-shaped, top ± flat. Face broadly elliptic to elliptic, up to 9 X 7 mm, mostly about 8 X 6 mm; the cell-lids often slightly ribbed or wrinkled transversely.
Seeds yellow-brown, smooth to rugose 1, flecked.
