Lithops gesineae H.W. de Boer (1955)


var. gesineae



     

Origin:


Collected by Franz S. Erni in 1938, and again in 1952 by his son, Herbert F.J. Erni, under namtipgbergensis, named for Mrs Gesine de Boer-Weyer, wife of Dr H.W. de Boer.

Distribution:


Namibia, at only two known localities in the Namitibberg, 70 km north of Aus, and 80 km south-southwest of Maltahöhe. TL C207.
Stone: Reddish-brown weathered gneis; white and stained quartzite with some gneiss.

Description:


Relatively uniform and fairly easy to identify.
Profile cordate-truncate; usually distinctly convex; fissure fairly deep, 6-12 mm, lobes conjunct, often slightly divergent at the top.
Face flush to slightly elevated; elliptic to slightly reniform; lobes mostly ± equal; opaque + transluscent; smooth.
Margins distinctly outlined but very irregularly dentate or sinuate, with numerous fairly bold peninsulas.
Windows usually ± occluded, rarely ± completely open.
Channels transluscent, narrow to broad, very irregular, often reduced to mini-windows in the islands and margins; often the mini-windows occur also on the shoulders and are then sometimes connected to the main channels by slender lines.
Islands usually distinct, small to large, mostly irregular in shape with a filigree pattern produced by the mini-windows within them.
Rubrications absent.
Dusky dots few to many, in the channels and mini-windows, mostly visible only with a lens.
Colours: Margins and islands opaque beige tinted with pink or yellow, or pink or greyish pink. Windows and channels transluscent greyish green or brown, greenish grey or brownish green, sometimes slightly redder along the inner margins and in the marginal indentations. Dusky dots dull dark grey-green. Shoulders pale greenish or pinkish or yellowish grey.
Size: Small to medium, facial diameters up to 36 X 27 mm, mostly about 28 X 18 mm. Number of heads up to 10 or more, mostly 1-2.

Flowers:


Yellow, medium to large, up to 45 mm Ø, mostly 25-35 mm Ø.
Seed capsules mostly 6-merous (76%), otherwise mainly 5-merous (15%), or 7-merous (8%). Profile boat-shaped, top flat to slightly convex. Face broadly elliptic to elliptic, up to 10 X 8,5 mm, mostly about 7,5 X 7 mm.
Seeds yellow-brown; rugose 1, flecked.

Lithops gesineae H.W. de Boer (1955)


var. annae H.W. de Boer (1956)



       

Origin:


Collected by Herbert F.J. Erni in 1952, and again by Dr and Mrs A.L. Geyer in May 1956; named for Mrs Anna E. Geyer-Joubert.

Distribution:


Namibia, at only two known localities, SW and SE of Helmeringhausen. TL SW of Helmeringhausen (C078).
Stone: Reddish-brown weathered gneiss.

Description:


Similar to the type variety, but generally larger and more reddish brown in colour.
Profile truncate-cordate; flat to slightly convex; fissure fairly deep, 6-12 mm, lobes conjunct, often slightly divergent at the top.
Face flush; mostly ± elliptic to slightly reniform; lobes mostly ± equal; opaque + transluscent; slightly rugose.
Margins usually distinctly outlined but irregular with numerous small indentations.
Windows usually ± occluded, rarely ± completely open.
Channels slightly impressed, irregular, broad to narrow, occasionally reduced to a network of shallow grooves, usually with few to many mini-windows in the margins and islands; the channels often taper off digitately into the outer margins and occasionally even over onto the shoulders.
Islands usually distinct, small to large, mostly irregular in shape.
Rubrications absent.
Dusky dots best seen with a lens, usually numerous, in the channels and mini-windows, and often at the ends of the digitate lines in the margins.
Colours: Margins and islands various shades of opaque beige tinted with pink or yellow, or grey, the margins occasionally obscurely banded in a slightly deeper hue. Windows and channels various shades of transluscent orange-brown, red-brown, brownish or reddish green or greenish brown; often lined with a deeper reddish colour along the inner margins and in the digitate marginal indentations, sometimes also around the islands. Dusky dots dark grey-green. Shoulders as for the margins, or a little lighter.
Size: Medium to large, facial diameters up to 40 X 30 mm, mostly about 30 X 20 mm. Number of heads seldom more than 1, occasionally 2.

Flowers:


Yellow, medium to very large, up to 48 mm Ø, mostly 30-35 mm Ø.
Seed capsules mostly 6-merous (75%), otherwise mainly 5-merous (11%), 7-merous (8%), 8-merous 4% or 4-merous (2%). Profile boat-shaped, top flat to slightly convex. Face broadly elliptic to elliptic, up to 12 X 10 mm, mostly about 10 X 8,5 mm.
Seeds yellow-brown; rugose 1, flecked.
