Lithops dinteri Schwant. (1927)


subsp. dinteri


var. dinteri



 

Origin:


Collected by Ernst J. Rusch in August 1926, and named for Professor Moritz Kurt Dinter, who contributed so much to botanical knowledge in the course of several sojourns in South West Africa (now Namibia) during the years 1897-1935.

Distribution:


Namibia, to the W, SW, S and SSE of Warmbad, and within 40 km of the Orange River. TL 'Wittsand', SSE of Warmbad (C206).
Stone: Coarse pegmatite. Colours white, grey-white, pink, light brown.

Description:


Generally distinguished by the bold blood-red dots in the usually open windows.
Profile truncate, flat to slightly convex; fissure fairly deep, 6-10 mm; lobes conjunct.
Face flush to slightly elevated, elliptic-reniform; lobes equal-unequal; mostly transluscent; smooth.
Margins usually distinct and fairly regular, sometimes irregularly dentate or sinuate, with a number of smudge-like peninsulas.
Windows usually completely open and transluscent, occasionally occluded.
Channels absent, or manifest only as transluscent areas around the islands.
Islands usually absent, otherwise manifest as small or large, indistinct and irregular opaque flecks or smudges, which appear to be made up of aggregations of small dots.
Rubrications in the windows rarely absent, usually 5 to 15 or more dots, occasionally also dashes and/or hooks, usually very distinct and prominent, but sometimes barely visible without a lens.
Dusky dots usually not visible without a lens, few to many, mainly in the marginal areas.
Colours: Margins and islands opaque pale buff to yellowish, greenish or pinkish grey, the margins sometimes indistinctly banded with a slightly deeper colour. Windows and channels various shades of transluscent grey or grey-green, often with a reddish tint. Rubrications blood-red. Dusky dots dull greenish grey. Shoulders usually a little lighter than the margins.

Lithops dinteri (1985)


subsp. dinteri


var. dinteri

Origin:


Specimens of this form appeared among seedlings grown by Ed Storms, USA, and apparently also by one or more collectors in Japan, from seed supplied by D.T. Cole from plants collected in colony C206.

Description:


Very distinctive in colour, but in all other respects the same as the type.
Colours: Margins and islands opaque pale creamy yellowish green. Windows and channels obscurely transluscent greenish grey or greyish green. Rubrications usually very obscure, dull orange-red.

Channels absent.
Islands absent.
Rubrications frequently absent, usually fewer than 8 small dots, dashes, hooks, or irregular stars, often only one or two in each window.
Dusky dots obscure, seldom visible without a lens, few to many, scatterd irregularly in the windows and sometimes also in the margins.
Colours: Margins various shades of opaque beige or buff tinged with creamy yellow or pink. Windows various shades of obscurely transluscent greenish grey or greyish green. Rubrications blood-red to dark red. Dusky dots dull dark greyish green. Shoulders as for margins.
Size: Small, facial diameters up to 21 X 15 mm, mostly about 18 X 12 mm. Number of heads up to 10 or more, mostly 2-6.

Flowers:


Yellow, small to medium, up to 32 mm Ø, mostly 20-27 mm Ø.
Seed capsules mostly 5-merous (94%), otherwise 4-merous (4%), or 6-merous (2%). Profile boat-shaped, top flat to slightly convex or peaked. Face broadly elliptic to round, with hinge-rim, up to 7,5 X 6,5 mm, mostly about 6,5 X 6 mm.
Seeds yellow-brown, tuberculate 2, flecked brown.

Lithops dinteri Schwant. (1927)


subsp. frederici (D.T. Cole) D.T. Cole (1973)



 

Origin:


Collected by Frederick T. Herselman on 18 August 1968, and named for him; subsequently collected by D.T. & N.A. Cole on 3 July 1970.

Distribution:


RSA: CP, in a very small area near Pella, NW of Pofadder. TL 'Near Pella... on the flat top of a low hill' (C180).

Description:


Distinguishable from the type by its mostly cordate profile, more opaque face and more numerous rubrications.
Profile cordate-truncate, top surface occasionally almost flat, usually distinctly convex; fissure deep, 4-10 mm; lobes conjunct, occasionally very slightly divergent at the top.
Face flush; elliptic-reniform; lobes equal-unequal; opaque + obscurely transluscent; smooth.

Islands relatively few, mostly fairly large, indistinct with irregular fuzzy edges, and mostly composed of aggregations of small dots.
Rubrications usually numerous dots, short dashes and commas in the channels, and mini-windows.
Dusky dots sometimes visible without a lens, sometimes not at all, few to many in the channels and mini-windows, sometimes also in the opaque marginal areas and islands.
Colours: Margins and islands various shades of opaque creamy buff or beige tinged with yellow or pink. Channels various shades of obscurely transluscent greenish grey. Rubrications sometimes bright blood-red, mostly dull dark red. Dusky dots dull dark greyish green. Shoulders as for the margins.

Windows often absent or not clearly distinguishable, sometimes manifest as very obscurely transluscent areas.
Channels slightly impressed, often rather indistinct and usually fairly narrow, forming an irregular broken network or sometimes reduced to small pits.
Islands absent, or present only in the form of indistinct and irregular opaque areas ± enclosed by channels, these opaque areas often made up of dotted flecks and/or smudges.
Rubrications in the channels, numerous bold red lines, dashes, hooks and dots, which sometimes form an irregular broken network; very often the rubrications ± completely fill the narrow channels and pits.
Dusky dots not visible.
Colours: Face opaque buff to pale brown, beige or pinkish grey, the margins often indistinctly banded in a slightly deeper hue. Channels transluscent dull grey-green, often with a reddish tint.
