10. LITHOPS DOROTHEAE
Lithops Dorotheae. (Plate 9.) Growths forming clumps of 5–7; top of leaves
convex or plane; window large, open, transparent; in the window a number
of small irregularly shaped islands, buff coloured; in the windows a number
of blood red, short lines and small dots, some of the lines in the immedi
ate neighbourhood of the outer margin bifurcated and the bifurcations end
in the sinuses of the outer margin; outer margin irregularly serrated; inner
margin straight and sometimes there are a number of blood red dots, lines
more or less parallel and near to the margin. In the older stage the margin
of the window is buff coloured, otherwise the colour is of a lighter tint. In
the window there are in the older stage a number of light green to deep dark
black miniature windows. Flowers yellow. bifurcatins > bifurcations
Namaqualand: Pella. (Fig. 32).
This plant is related to L. Dinteri, which grows just across the Orange
River on its northern side. There are 10–15 prominent red spots on each lobe
of L. Dinteri, whereas one finds blood red dots and lines, the latter very often
bifur cated in L. Dorotheae. L. Dorotheae is also related to L. Bromfieldii, but the
latter has a far greater number of blood red dots and lines and its window is
dark green, whereas that of L. Dorotheae is transparent and light green.
