Lithops aucampiae L. Bol. (1932)


subsp. aucampiae
var. aucampiae L. Bol. (1932)



       

Origin:


Collected by Miss Juanita Aucamp on her father's farm in May 1929, and named for her. A later collection (NBG 616/31) was made by D. McCormick in 1931.

Distribution:


RSA: CP, in a large roughly triangular area with points near Severn, west of Vryburg, and north of Niekerkshoop. TL 'Griqualand West: Postmasburg' (C255).
Stone: Banded ironstone with sandstone or chert; dark ferruginous quartzite; quartzite with some very fine-grained sandstone Colours mainly brown, yellow-brown, black with some red, grey, white.

Description:


Rather variable, but fairly easily recognizable. Occasional specimens have the channels reduced to very slender grooves and mini-windows as in var. koelemanii.
Profile truncate top surface sometimes ± flat, mostly slightly convex; fissure shallow, 3-7 mm; lobes conjunct.
Face flush, elliptic-reniform; lobes equal-unequal; opaque + obscurely transluscent; smooth to slightly rugose.
Margins usually distinct, narrow to broad, sometimes fairly regular to dentate but usually very irregularly incised with numerous peninsulas.
Windows usually ± occluded, occasionally ± completely open, sometimes reduced to very narrow channels and mini-windows, usually with a number of fine irregularly forked lines tapering off into the margins and sometimes over the shoulders.
Channels narrow to broad, irregular.
Islands sometimes somewhat obscure, usually distinct, few to many, small to large, very irregular, sometimes slightly raised.
Rubrications absent.
Dusky dots usually not visible without a lens, occasionally quite obvious, few to many in the channels and mini-windows.
Colours: Margins and islands various shades of opaque yellowish to reddish brown, always different from the windows or channels, the colours of the margins often more intense than those of the islands. Windows and channels various shades of obscurely transluscent yellowish to reddish chocolate brown, sometimes very dark. Dusky dots slightly glossy graphitic dark greenish grey. Shoulders various shades of milky violaceous, pinkish or reddish grey or brown.
Size: Medium to very large, facial diameters up to 53 X 37 mm, mostly about 35 X 25 mm. Number of heads up to 12 or more, mostly 2-5.

Flowers:


Yellow, medium to very large, up to 52 mm Ø, mostly 30-40 mm Ø.
Seed capsules mostly 6-merous (89%), otherwise 7-merous (7%), or 5- and 8- merous (4%). Profile boat-shaped, top mostly ± flat. Face broadly elliptic, up to 13 X 10 mm, mostly about 10 X 8 mm.

Lithops aucampiae L. Bol. (1932)


subsp. aucampiae
var. aucampiae
acf 'Betty's Beryl' (1988)



Origin:


This form appeared in cultivation in the USA in 1976 or thereabouts; it was first observed in Johnson's Cactus Gardens, California. Its provenance is not known. We are indebted to Steven Hammer and Elizabeth Athy for information and for a specimen of this form.

Description:


Flowers white (instead of yellow), the plants are also very distinctive in colour, but in all other respects the same as the type.
Colours: Margins and islands opaque light yellow-green. Windows & channels transluscent greyish green. Dusky dots very obscurely visible with a lens, slightly darker than the channels. Shoulders opaque greyish green.

subsp. aucampiae
var. aucampiae
acf 'Jackson's Jade' (1992)



Origin:


This form appeared in cultivation in the collection of Tim Jackson, California, USA.

Description:


The plants very distinctively green or yellow-green in colour, but in all other respects the same as the type.
Colours: Margins and islands opaque light yellow-green. Windows & channels transluscent greyish green. Dusky dots very obscurely visible with a lens, slightly darker than the channels. Shoulders opaque greyish green.

Lithops aucampiae L. Bol. (1932)


subsp. aucampiae
var. aucampiae
acf 'Storm's Snowcap' (1985)



Origin:


This white-flowering form appeared among seedlings grown by Ed Storms, USA, but the provenance of the seeds is unfortunately unknown.. However, there have been various reports, from time to time, of white-flowering specimens of var. aucampiae, and it is quite possible that other specimens are in cultivation and that this mutant occurs in more than one colony.

Description:


Flowers white (instead of yellow), but the plants are otherwise indistinguishable from the type, and are therefore identifiable only when in flower.

Margins generally not clearly distinguishable, but inner margins sometimes well defined.
Windows usually absent, rarely manifest as channels between islands, or as an obscurely translucent 'shadow'.
Channels mostly reduced to very narrow slightly impressed grooves and mini-windows, forming and extensive broken network, which may extend into and taper off in the margins; rarely somewhat broader, as in the type.
Islands absent except in the rare specimens with broader channels.
Rubrications absent.
Dusky dots usually not visible without a lens, few to many, in the grooves and mini-windows.

Size: Medium to very large, facial diameters up to 47 X 36 mm, mostly about 35 X 25 mm. Number of heads up to 24 or more, mostly 2-5.

Flowers:


Yellow, medium to very large, up to 55 mm Ø, mostly 30-45 mm Ø.
Seed capsules mostly 6-merous (95%), otherwise 5- and 7- merous (5%). Profile boat-shaped, top mostly ± flat. Face broadly elliptic, up to 13 X 11 mm, mostly about 11,5 X 9,5 mm.
Seeds light brown, rugose 2, flecked brown.
