Lithops fulviceps (N.E. Brown) N.E. Brown (1914)


var. fulviceps



     

Origin:


Collected by Professor H.H.W. Pearson, University of Cape Town, in 1912. Latin fulvi- 'yellow-brown, tawny', -ceps 'head'.

Distribution:


Namibia, in a narrow strip extending northwards for about 100 km from the vicinity of Karasburg, the TL at Narudas (C220) being near the northern end of this area; and an isolated locality (as far as is known at present) near Lutzputs, Cape Province, over 180 km ESE from Karasburg. Westerly localities reported to the NE and SW of Klein Karas have not yet been confirmed.
Stone: Quartzite; gneiss; quartzite and schist; calcrete and quartzite. Colours light to dark brown or reddish brown with some white and grey-white, or grey-white with some dark brown.

Description:


Somewhat variable in colour and by no means always tawny, but otherwise very uniform.
Profile truncate; flat to slightly convex; fissure shallow, 5-8 mm, lobes conjunct.
Face flush; elliptic-reniform; lobes equal-unequal; mostly opaque; slightly rugose.
Margins generally absent.
Windows, Channels and Islands generally absent or not clearly distinguishable, but the face ± reticulated by slightly impressed grooves or furrows; in some specimens the window area is very obscurely transluscent, and indistinct margins, channels and islands are then discernable.
Rubrications occasionally absent, usually few to many slightly impressed dots, dashes or slender and irregularly branched lines which are often indistinct and best seen with a lens, but sometimes they form a conspicuous network.
Dusky dots up to 1 mm or more Ø, usually but not always slightly raised, like minature blisters, scattered irregularly over the whole face, sometimes extending onto the shoulders, and occasionally so numerous as to flow together and produce the semblance of a window.
Colours: Face generally opaque, various shades of fairly uniform rusty yellow-brown, orange-brown, red-brown, grey-brown, sometimes grey with greenish or pinkish or purplish tinges; margins, though usually indistinct, may occasionally manifest a slightly deeper hue; in specimens with obscurely transluscent windows, these areas are greenish or brownish grey, reddish green, greenish or reddish brown. Rubrications deep yellow to orange-brown to red. Dusky dots dark grey-green to blue-green. Shoulders often as for the face but duller, or yellowish, reddish or bluish grey.
Size: Medium to large, facial diameters up to 40 X 27 mm, mostly about 30 X 23 mm. Number of heads up to 10 or more, mostly 2-3.

Flowers:


Yellow, medium, up to 35 mm Ø, mostly 25-30 mm Ø.
Seed capsules mostly 5-merous (90%), otherwise 6-merous (8%), or 4-merous (2%). Profile boat-shaped, top flat to slightly convex. Face broadly elliptic to elliptic, up to 12 X 9 mm, mostly about 8,5 X 7 mm.
Seeds yellowish brown to brown; smooth to rugose 1, brown.

Lithops fulviceps (N.E. Brown) N.E. Brown (1914)


var. fulviceps acf 'Aurea' (1977)



Origin:


This form first appeared among seedlings grown in the USA and in Japan. Its source in habitat is not known Originally published as L. fulviceps f. aurea Y. Shimada. Latin aurea 'golden yellow'.

Description:


Flowers white (instead of yellow), and the plants also very distinctive in colour, but in all other respects the same as the type.
Colours: Face opaque creamy yellow-green or bluish green. Windows usually absent, occasionally very obscurely transluscent greyish green, the obscure margins paler yellowish green. Rubrications sometimes absent, otherwise very fine pale brownish-orange dots and mostly short lines, often barely perceptible. Dusky dots usually slightly raised, dark dull greyish or bluish green. Shoulders as for the face, or slightly darker or greyer.

Flowers:


White, otherwise as for the type.
Seed capsules mostly 5-merous (81%), otherwise 6-merous (19%).

Lithops fulviceps (N.E. Brown) N.E. Brown (1914)


var. lactinea D.T. Cole (1973)



   

Origin:


Collected by D.T. & N.A. Cole on 2 July 1971 (C222, PRE). Latin lactinea 'milky, bluish white'.

Distribution:


Namibia, about 105 km ESE of Keetmanshoop and therefore over 35 km to the NNE of the main area of the type variety. Only one colony is known at present, growing on a 'gentle limestone slope' (C222).
Stone: Grey-white calcrete.

Description:


Except in colour, essentially as for the type.
Profile truncate; flat to slightly convex; fissure shallow, 5-8 mm, lobes conjunct.
Face flush; elliptic-reniform; lobes equal-unequal; mostly opaque; slightly rugose.
Margins generally absent or not clearly distinguishable, but the face ± reticulated by slightly impressed grooves or furrows; in some specimens the window area is very obscurely transluscent and indistinct margins, channels and islands are then discernible.

Flowers:


Yellow, small to medium, up to 32 mm Ø, mostly 20-25 mm Ø.
Seed capsules as for the type or a little larger; mostly 5-merous (72%), otherwise 6-merous (25%), or 4-merous (2%). Profile boat-shaped, top flat to slightly convex. Face broadly elliptic to elliptic, up to 12 X 9 mm, mostly about 8,5 X 7 mm.

Lithops fulviceps (N.E. Brown) N.E. Brown (1914)


var. laevigata D.T. Cole (2006)



     

Origin:


Collected by D.T. & N.A. Cole on 7 May 2004 in the Norhern Cape, -28 19DC (C412, PRE, holo, iso.). Latin laevigata 'having a smooth surface, as if polished'. Named because of its relatively smooth surface with small subcutaneous dots, not the large raised dusky dots which characterize the type variety. The plants are also distinctly smaller in all dimensions, with rarely visible rubrications.

Distribution:


Northern Cape, in one colony, to the northeast of Pofadder. It is possible that other colonies may occur elsewhere in that area, especially to the north or northwest, in similar formations.
Stone: Quartzite gravel, mostly opaque white, with some pink or blue-grey.

Description:


A small and relatively uniform species, predominantly rusty brown in colour, with few distinguishable islands.
Profile mainly ± truncate; flat; fissure deep, up to 6 mm, lobes conjunct.
Face flush, mostly elliptic; lobes mostly ± unequal; semi-opaque to opaque; very slightly rugose.
Margins clearly distinguishable, rather irregular.
Windows mostly not clearly distinguishable.
Islands few and mostly not clearly distinguishable.
Rubrications rarely visible as very slender lines, dots, dashes and hooks, reddish in colour.
Dusky dots numerous, often in the margins and in obscurely visible windows.
Colours: Face (margins & islands) opaque to semi-opaque. Channels dark olive-green, obscurely transluscent. Shoulders as for the face.
Size: Small to medium, facial diameters up to 27 X 18 mm, mostly about 20 X 15 mm (exceptional specimens, growing in the shade, up to 29 X 24 mm). Number of heads up to 3 or more, mostly 1-2.

Flowers:


Yellow, medium, rarely up to 35 mm Ø, mostly 25-30 mm Ø.
Seed capsules mostly 5-merous (89%), otherwise 6-merous (11%). Profile boat-shaped, flat. Face broadly elliptic to elliptic, up to 6 X 5 mm.
Seeds light yellow-brown; smooth to rugose 1, occasionally flecked.
