L. herrei
    acf 'Splendido'



Lithops herrei L. Bol (1932)



       

Origin:


Collected in October 1930 by Dr Adolar Gottlieb Julius (Hans) Herre, Curator of the Botanic Garden, University of Stellenbosch, and named for him.

Distribution:


RSA: CP, in a narrow strip about 70 km long and no more than 10 km wide, along the Orange River from Alexander Bay to Sendelingsdrif; and in Namibia, at localities W and SW of Sendelingsdrif. TL Swartwater, Richtersveld, CP (C235).
Stone: Quartzite and schist; amygdaloidal lava and calcrete. Colours grey-white, black, white, grey, brown.

Description:


As in Lithops optica, there are two forms of this species, the non-maculate, which occurs relatively near to the coast (within 30 - 40 km) and at low altitudes, and the maculate or more opaque form, which occurs further inland and at somewhat higher altitudes. In intermediate localities (including the type locality), both forms are represented, so it would be inappropriate to treat them as varieties. One of the localities in Namibia is the furthest inland, and the highest, and the plants occuring there are the most opaque.
Profile cordate-truncate, occasionally slightly bicuneate; top surface occasionally flat but usually convex and often slightly humped, one side of the face sometimes lower than the other, producing a somewhat lopsided effect; fissure deep, 7-15 mm; lobes conjunct or slightly divergent.
Face flush to slightly elevated; elliptic-reniform; lobes mostly somewhat unequal; opaque + transluscent; smooth to slightly rugose.
Margins sometimes well-defined and fairly regular or slightly indented, usually somewhat indistinct and very irregular with numerous peninsulas, occasionally not distinguishable at all.
Windows sometimes ± completely open, usually ± occluded, occasionally absent, the face then being almost completly opaque.
Channels broad to narrow, irregular, occasionally reduced to a number of slightly impressed irregular grooves and mini-windows, forming a very irregular fine lacework; sometimes further reduced to a number of unconnected narrow grooves or isolated mini-windows in an opaque face.
Islands few to many, small to large, mostly very irregular, often reduced to indistinct mottling or flecks, resembling cobwebs or lacework.
Rubrications absent.
Dusky dots seldom visible even with a lens, few to many.
Colours: Face (margins and islands) various shades of opaque pale milky grey or pale grey tinged with green, blue, cream, yellow, pink or buff, the margins sometimes faintly edged in a slightly paler tint. Windows and channels various shades of transluscent pale to mid-grey, bluish, greenish, yellowish or pinkish grey, or greyish, brownish or bluish green. Dusky dots dull bluish grey-green. Shoulders as for the margins, or greyer and duller.
Size: Small to medium, facial diameters up to 30 X 21 mm, mostly about 23 X 17 mm. Number of heads up to 20 or more, mostly 2-7.

Flowers:


Yellow, occasionally bronze-yellow, with white centre, very small to small, up to 23 mm Ø, mostly 15-20 mm Ø
Seed capsules mostly 5-merous (95%), otherwise 6-merous (4%), or 4-merous (1%). Profile boat-shaped, top ± flat, usually with a dark line up to 1 mm wide just below the edge. Face broadly elliptic to elliptic, with hinge-rim, up to 9 X 7 mm, mostly about 7 X 6 mm; cell-lid edges very distinct.
Seeds light brown to brown; tuberculate 1, flecked.
