Lithops terricolor N.E. Br. (1922)



       
       

Origin:


Collected by Frank Frith, presumably in 1921. Latin terricolor 'earth colour'.

Distribution:


RSA: CP, in a large roughly quadrangular area based on Laingsburg, Merweville, Graaff Reinet and a point NW of Port Elizabeth. We have not yet been able to confirm reports of this species occuring to the N of Grahamstown and near Adelaide, CP. TL 'Laingsburg Division: near Grootfontein ... on black shale and on gravelly ground' (C132).
Stone: Shale; weathered fine-grained feldspathic sandstone; quartzite; quartzite with fine-grained sandstone; siltstone; banded cherts and jasper. Colours dark grey, grey-brown, grey-white, yellow-brown, brown, some red, pink, white, black.

Description:


Distinguished by its very dense pattern of dusky dots (or mini-windows) and easily recognizable. It has been stated repeatedly that in this species windows are nearly always absent, but this is not true. Open-windowed plants occur quite often in most colonies, and in some localities they are very much in the majority.
Profile mostly cordate, sometimes somewhat truncate; top surface sometimes ± flat, usually distinctly convex; fissure fairly deep, 5-12 mm; lobes conjunct, occasionally slightly divergent.
Face flush; mostly ± elliptic, occasionally slightly reniform; lobes equal-unequal; opaque to transluscent; smooth.
Margins very often not clearly distinguishable, but in open-windowed plants fairly well-defined
Windows sometimes ± completely open or partly occluded, but usually absent, the face then very densely dotted with dusky dots which often extend into the marginal area and over onto the shoulders.
Channels usually not distinguishable, otherwise obscure, narrow to broad, very irregular.
Islands usually fairly small, few to many, very irregular, often rather obscure flecks, and incorporating numerous mini-windows.
Rubrications absent.
Dusky dots usually very numerous, superficial and clearly visible, often extending into the marginal area and onto the shoulders; in channels and open windows the dusky dots are obscured and best seen with a lens.
Colours: Face (margins & islands) various shades of opaque pale pinkish, yellowish, greenish or bluish grey, or pinkish, yellowish or reddish brown, or greyish blue, green or lilac; the margins occasionally lightly suffused with yellowish or pinkish beige, to form an obscure band. Windows & channels various shades of obscurely transluscent dark greenish grey or greyish green. Dusky dots dull dark greyish green. Shoulders milky grey or bluish, pinkish, greenish or yellowish grey, usually matching the colour of the face, but lighter, contrasting with the marginal zone.
Size: Small to medium, facial diameters up to 30 X 24 mm, mostly about 20 x 15 mm. Number of heads up to 20 or more, mostly 2-5.

Flowers:


Yellow, sometimes with white centres; small to medium, up to 35 mm Ø, mostly 15-25 mm Ø.
Seed capsules mostly 5-merous (96%), otherwise mainly 6-merous (4%). Profile boat-shaped, top ±flat to slightly convex or peaked. Face broadly elliptic to almost round, up to 8 X 7 mm, mostly about 6,5 X 5,5 mm.
Seeds yellow-brown; smooth to rugose 1, flecked.

Lithops terricolor N.E. Br. (1922)


acf 'Silver Spurs'

(1985)

Origin:


Collected by Johann van Schalkwyk in 1978.

Distribution:


Known only from one colony E of Laingsburg, CP (C132), where only one specimen of this form was found.

Description:


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

Lithops terricolor N.E. Br. (1922)


acf 'Speckled Gold'

(1985)

Origin:


Collected by Johann van Schalkwyk in 1978.

Distribution:


Apparently restricted to a single colony NW of Prince Albert Road, CP (C345), where only one specimen of this form was found.

Description:


Very distinctive in colour, but in all other respects the same as for the type.
Colours: Face (margins & islands) opaque golden yellow. Channels (very obscure) dull greenish grey. Dusky dots dark greyish green, contrasting strongly with the golden-yellow face. Shoulders pale creamy green.

acf 'Violetta'

(1999)

Description:


Derived from seed from plants collected at Laingsburg. Differs from the type in having a reddish-violet colour.
