Lithops - Au Cactus Francophone

odies. As far as the leaves go, L. Helmuti would he placed among tile smaller
species of Lithops; but with cultivation one would expect a considerable in
crease in the size of these organs. The flower is about the average size found
in the genus, being, when well flattened by hand, nearly an inch and a half
in diameter. There are five sepals, the outer ones obtuse, and the inner ones
more or less acute. The golden yellow petals are in about two series as regards
their length, obtuse or notched at the apex and narrow at the base, where
the yellow fades to white.
The stamens slightly overtop the five pale green stigmas, the filaments
being white and the anthers and pollen rather a dull pale yellow. The top of
the ovary is concave and is not even raised in the middle, and the five lobes
are scarcely visible. The leaves are dove grey in the lower part and a duller
grey above, the window being greenish grey with fawn grey markings. The
branching pattern on the window is rather vague and inconspicuous and not at
all raised at the surface. The pattern extending from the margin inwards (and
it may he noted that this occurs from the inner margin, that is, where the
leaves face each other, as well as the outer) is perhaps a little more definite;
the window itself is among the most convex I have seen; measured from the
one side of the leaf it is up to 8 nun, in height.
