Lithops julii (Dint. & Schwant.) N.E. Br (1925)


subsp. julii



       

Origin:


Collected by Professor Kurt Dinter in February 1924, and named for his friend, Dr Julius Derenberg of Hamburg, Germany.

Distribution:


Namibia, in a triangular area including Karasburg in the north, and in the south, points on the Orange River some 70 km SW and SE of Warmbad, roughly halfway between Vahldorn and Warmbad.
Stone: Fine- or coarse-grained pegmatite; pegmatite gravel. Colours white, grey-white, pink, brown, grey, red.

Description:


Enormously variable, some specimens being opaque and almost uniform in colour, others opaque but strongly reticulated with fine impressed markings, yet others with largely open obscurely transluscent windows. At least three main forms have been recognized and were even given varietal status or proposed for it (pallid, reticulated and fuscous) but although most colonies tend to have a majority of one or other of these types, all have at least two and many have all three of them. A distinctive feature of this subspecies is the 'lip-smear' along the inner margins, though this is not always present.
Profile truncate; top surface flat to slightly convex, occasionally slightly concave; fissure deep, 5-10 mm; lobes conjunct, sometimes slightly divergent.
Face flush, mostly slightly reniform; lobes equal-unequal; mostly opaque; smooth to slightly rugose.
Margins usually rather obscure, sometimes ± distinct but irregularly dentate or sinuate, with a number of peninsulas; along the inner margins, usually a fuscous lip-smear, sometimes entire and prominent, sometimes fragmented and obscure, occasionally absent; the fuscous suffusion of the lip-smear occurs occasionally as a narrow edging or lining all along the outer margins.
Windows usually ± occluded, infrequently ± completely open.
Channels irregular, sometimes broad and distinct, often rather obscure; frequently reduced to a coarse or fine network of narrow, slightly impressed grooves.
Islands usually large, sometimes small, mostly well-defined and distinct but sometimes obscure and indistinct against the background of opaque channels.
Rubrications sometimes absent, usually a network of lines in the channels, sometimes very bold and prominent, but often reduced to a number of isolated and obscure short lines, hooks and/or dots; such a line, or row of dots, may also occur in the lip-smear or may replace it sometimes when the latter is absent.
Dusky dots not visible.
Colours: Margins and islands various shades of opaque whitish grey, sometimes tinged with blue, mauve, pink or buff; lip-smear and marginal lining dark greenish or brownish grey, greenish brown or beige. Windows and channels sometimes opaque grey-white with various tints of blue, mauve, pink, beige or brown; sometimes obscurely transluscent greenish grey, greenish or yellowish brown, or pinkish grey. Rubrications bright to dark red, sometimes very obscure and visible only under a lens. Shoulders as for the margins and islands, or a little paler.
Size: Small to medium, facial diameters up to 38 X 25 mm, mostly about 25 X 20 mm. Number of heads up to 8 or more, mostly 2-4.

Flowers:


White, medium to large, up to 43 mm Ø, mostly 25-35 mm Ø.
Seed capsules mostly 5-merous (90%), otherwise mainly 6-merous (7%), 4-merous (2%) or 7-merous (1%). Profile boat-shaped, top ± flat. Face elliptic to narrow elliptic, up to 11 X 7,5 mm, mostly about 8,5 X 6 mm.
Seeds yellow-brown to light yellow-brown, smooth to rugose 1, flecked.

var. fulleri



       

Origin:


Collected by Ernest Russel Fuller, Postmaster at Kenhardt, in 1926 or earlier, and named for him.

Distribution:


RSA: CP, in a large quadrangular area including Kenhardt in the SE, Gamoep and Beenbreek (SE and NE of Springbok) in the W, and Grondneus (NW of Upington) in the N. TL 'near Kenhart'.
Stone: Fine- or coarse-grained pegmatite; granite; fine-grained pegmatitic granite; calcrete in granitic soil. Colours white, grey-white, pink, brown, grey.

Description:


Extremely variable in colour, pattern and rubrication.

Face flush, mostly reniform; lobes mostly somewhat unequal; opaque, occassionally obscurely transluscent; mostly somewhat rugose.
Margins distinct, narrow to broad, usually irregularly dentate, sometimes sinuate with quite large peninsulas; both inner and outer margins usually edged with a fuscous lining.
Windows distinct, slightly impressed, usually ± occluded, sometimes completely open, occasionally reduced to a network of narrow grooves.
Channels broad to narrow, slightly impressed, somewhat irregular and sometimes tapering off into the margins.
Islands usually fairly regular in shape, few to many, mostly fairly small, sometimes large; usually distinct, sometimes reduced to rather obscure flecks.
Rubrications may be completely absent, or constitute a fairly bold broken network, but usually appear mostly in the marginal indentations, as a series of dots, dashes or X, Y or V marks, giving the impression of irregular stitching, with only a few scattered occurrences, if any, in the window area.
Dusky dots not visible.
Colours: Margins and islands various shades of opaque light grey, faintly tinged with pink, yellow, blue or green, or beige or buff. Windows and channels various shades of opaque (or occasionally, obscurely transluscent) milky blue, pale pinkish, greenish or yellowish grey, or mauve, pink or rust-brown; usually with a brown or dark greenish-brown smear thinly lining both inner and outer margins; sometimes this suffusion is more extensive and also surrounds the islands; and even washes onto them. Rubrications bright to dark blood-red, red-brown or purplish red. Shoulders as for the margins or slightly lighter.
Size: Small to medium, facial diameters up to 32 X 23 mm, mostly about 25 X 18 mm. Number of heads up to 15 or more, mostly 2-5.

Flowers:


White, medium to large, up to 45 mm Ø, mostly 25-35 mm Ø.
Seed capsules mostly 5-merous (78%), otherwise mainly 6-merous (18%), 7-merous (3%). Profile boat-shaped, top flat to slightly convex. Face narrowly to broadly elliptic, up to 9 X 7 mm, mostly about 7,5 X 5,5 mm.
Seeds light yellow-brown to yellow-brown, rugose 1.

subsp. fulleri


var. rouxii (H.W. de Boer) D.T. Cole (1964)



       

Origin:


Collected by A.A. Roux in May 1963, and named for him.

Distribution:


Namibia, to the W and SW of Warmbad; TL '30 miles SW of Warmbad'. This area is separated by a distance of some 70 km from the range of var. fulleri, to which var. rouxii is closely related.
Stone: Pegmatite; fine-grained gneiss with some pegmatite. Colours white, grey-white, brown, pink, green.

Description:


Very close to var. fulleri, but even more distinctively marked with stitchlike marginal rubrications.
Profile truncate; flat to slightly convex; fissure fairly deep, 6-12 mm; lobes conjunct to slightly divergent.
Face flush, mostly reniform; lobes mostly ± unequal; opaque; slightly rugose.
Margins well-defined but with irregular indentations, and within them a distinctive series of dark rubrications which resemble stitches.
Windows slightly impressed below the level of the margins and islands; often completely open but opaque, otherwise ± occluded.
Channels irregular, narrow to broad; usually opaque, very occasionally obscurely transluscent.
Islands very slightly raised but usually rather indistinct against the opaque background of the channels; mostly relatively large and fairly regular in shape.
Rubrications mostly confined to the indentations in the outer margins, where they occur as a series of dots or short dark lines similar to the symbols I,V,W,X,Y, thus resembling stitches; but sometimes along the inner margins and within the windows a few isolated short dashes and dots, or, very rarely, even an irregular broken network of lines..
Dusky dots not visible.
Colours: Margins usually very distinctly banded with a suffusion of opaque beige or buff, sometimes tinged with pink, yellow or brown. Windows and channels usually various shades of opaque bluish or mauvish grey, or beige or buff; in the marginal indentations, often small ± triangular areas of obscurely transluscent greenish grey or brownish green, in which the rubrications are set.

Shoulders mostly grey-white, sometimes tinged with pink, blue or green.
Size: Medium to large, facial diameters up to 40 X 25 mm, mostly about 30 X 20 mm. Number of heads up to 6 or more, mostly 2-3.

Flowers:


White, small to large, up to 42 mm Ø, mostly 20-35 mm Ø.
