Lithops amicorum D.T. Cole (2006)



Collected by Desmond T. and Naureen A. Cole on 3 May 2004. Named amicorum for the group of four friends who discovered it.


Namibia to the southeast of Aus, in three colonies, two of them on neighbouring quartzite ridges in close proximity to one another, the third about a kilometre away. It is possible that other colonies may occur on neighbouring farms.
Stone: Quartzite gravel, mostly opaque white, some pink, yellow; also some black or near black dolerite, and micaceous schist.


A very small and relatively uniform species. Predominantly greyish to blueish white in colour, usually with numerous small grey-white islands. This is the smallest species yet recorded, being rivalled only by L. dinteri subsp. frederici.
Profile mainly ±truncate to slightly convex, fissure deep, up to 5 mm; lobes conjunct.
Face flush, mostly elliptic; lobes mostly ± unequal in size, opaque, very slightly rugose.
Margins irregular, incised-sinuate; inner margins slightly more regular.
Windows very slightly impressed, sometimes open, usually with few to several islands.
Islands usually numerous, irregularly-shaped opaque areas enclosed by channels.
Rubrications faintly visible as slender lines, dots, dashes and hooks, reddish in colour.
Dusky dots not visible.
Colours: Face (margins and islands) opaque pale greyish white. Channels opaque pale bluish white. Shoulders as for the face.
Size: Very small to small, facial diameters up to 19 X 13 mm, mostly about 15-10 mm. Number of heads up to 4 or more, mostly 1 or 2.


White, very small to medium, rarely up to 30 mm Ø, mostly 20-25 mm Ø
Seed capsules mostly 5-merous (90%), rarely 6-merous (6%), otherwise 4- and 7- merous (4%). Profile boat-shaped, slightly convex. Face broadly elliptic, mostly 5 X 4 mm.
Seeds light yellow-brown; rugose 1. occasionally flecked.
