49. LITHOPS VERRUCULOSA
Lithops verruculosa. (Plate 42.) Growths up to 6 in a body; lobes sub
equal; upper surface opaque, irregularly divided by a number of confluent
depres sions, giving the whole a wrinkled or tuberculate appearance, like that
of L. turbiniformis, bluish grey; in the depressions a very large number of
minute dark grey warts; outer and inner margins with lines. Flower not
seen. (Fig. 114.)
North West Cape.
This is undoubtedly a distinct species related to L. turbiniformis. It
differs from the latter: (i) this species is of a bluish grey colour, whereas L.
turbiniformis is rust brown or at least of a reddish tint colouration; (ii) in
between the tubercles or wrinkles are depressions and here are found minute
dark grey warts, a feature not observed so far in any other Lithops species,
and characteristic of this species. These minute warts are distinctly visible
under a 10 lens or very slightly with the naked eye. Fig. 115 gives an idea
of the wrinkles and the colour of the plant.
Fig. 116 is a photograph of one of the lobes of this species, and was
taken with a Leitz Panphot, using an objective Millar 100 mm. This shows
the convolutions quite clearly, and in these depressions the small warts are
visible at some points.
