24. LITHOPS KARASMONTANA<br />

<strong>Lithops</strong> karasmontana. (Plates 20, 20a. 20b.) Growths solitary or forming<br />

clumps of 2 or more. top more or less flat or convex; sides coloured mauve grey;<br />

rugu lose or slightly bullate at times, windows usually opaque; top uniform col<br />

our, light grey pale brown yellow, the depressions being of a darker tint or in<br />

the depressions brown ochre lines or at times only a brown ochre dot; here<br />

and there is a deeper depression; at times the depressions are of a dark green<br />

colouration forming a window and these depressions become confluent forming<br />

a fairly large semi transparent window. Flowers yellow.<br />

South West Africa: Karas Mts.: Kl. Karas Mts. among quartz pebbles;<br />

foot of Kl. Karas Mt. near Klein Karas. Fl. Oct. Nov.<br />

L. karasmontana is one of the most variable species of this genus. The varia<br />

tion is of a twofold nature: (1) The colour of the elevations or ridges varies<br />

front a light fawn grey, brown, dark brown, reddish brown to a distinct red<br />

dish tint. All these variations were observed in one of two clumps brought<br />

fresh from the field in South West Africa. An attempt has been made—by, I<br />

think, Schwantes—to nature a species L. Jocobseniana, mainly because of the<br />

reddish tint of the ripper surface. To tiny mind this is not a good species,<br />

and though it was not described it does appear in the literature. I reckon<br />

it should not be retained. (2) The colour of the depressions is also liable<br />

to vary. The variation from fawn, fawn grey, dark brown, ochre brown to a<br />

distinct brown with a tinge of red. In spite of these variations the species<br />

is easily recognised by (i) the peculiar rugose surface and (ii) the somewhat<br />

darker colour of the depressions. Fig. 58 shows clearly the range of the varia<br />

tion as all these plants conic front uric habitat. Fig. 59 shows quite distinctly<br />

the nature of the rugosity and the deeper colour of the depressions.<br />
