DESCRIPTION:--Plant dwarf, succulent, spineless, branching from the
base. _Branches_ ascending or somewhat spreading, 2·5 to 15 cm. long, 1
to 1·4 cm. thick, cylindric or slightly tapering upwards, tessellately
tuberculate with hexagonal flattish tubercles 6 to 10 mm. in diam.,
having a slightly prominent whitish leaf-scar, glabrous, dull green.
_Leaves_ sessile, soon deciduous, 4 to 6 mm. long, 3 to 4 mm. broad,
elliptic or elliptic-oblong, acute, dark green, with a reddish minutely
toothed margin. _Peduncles_ 3 to 4 at the ends of the branches, about 4
mm. long, bearing a pair of ovate or elliptic bracts and 1 involucre,
glabrous. _Involucre_ about 1·3 to 1·8 cm. in diam., cup-shaped,
glabrous, with 5 glands and 5 transversely oblong, toothed and ciliate,
inflexed, purplish lobes. _Glands_ subcontiguous, about 5 mm. in diam.
across the tips, very concave at the basal part, divided into 3 to 4
spreading finger-like corrugated white processes 2 to 3 mm. long.
_Ovary_ pedicellate, scarcely exserted, with styles 7 mm. long, united
for two-thirds of their length, with entire spreading tips. (National
Herb., Pretoria, No. 2989.)

This Plate, and that on Plate 117, should be compared with _Arctotis
Fosteri_ which we figured on Plate 3, when the difference between the
genera _Venidium_ and _Arctotis_ will be seen. In the former genus the
fruits are without a pappus or with a very rudimentary one, while in the
latter genus a well-developed pappus is always present.
The plant is commonly known as the “Namaqua Daisy,” and in its native
home the flower-heads attain a very large size when the season is
favourable, but may be quite small when no rain has fallen. _Venidium
Wyleyi_ does quite well under cultivation, and is easily grown and forms
a very effective border.
We are indebted to Mr. L. R. Vogt of Waterkloof near Pretoria for the
specimens, which were grown in his garden.
