covering. In this covering a number of small round openings, whereby the
transparent window becomes visible. In the irregular window a large number
of large, grey coloured islands of irregular shape. In these islands here and
there a small number of round openings. Outer margin denticulate or con
sisting of a large number of irregularly shaped laciniae connected to the is
lands. Inner margin irregular. Both margins coloured grey. Capsule 5 locular.
Flowers unknown. (Fig. 111–113.)
Griqualand West: Boetsap in limestone.
This species occupies an isolated position as far as the grey colour is
concerned, but it is definitely related to L. Lesliei. It differs from the lat
ter species in that the grey islands are raised above the level of the window
and thereby giving the whole a rough appearance. The dominant colour of
L. Lesliei is rust brown to a greenish, and the network of L. Lesliei is much
more delicate than that of L. Venteri. The characteristic common to both is
the minute circular openings in the islands or the covering of the window.
Presumably the colour of the flower is yellow.
