In a collection of succulents received from South-West Africa and
planted at the Division of Botany, Pretoria, fruits of this _Gazania_
were evidently mixed with the soil, as a plant grew in the succulent
bed. It is a somewhat remarkable species and differs considerably in
habit from the two species previously figured on Plates 51 and 64. The
whole plant is covered with cobwebby hairs. The leaves are somewhat
succulent, extremely brittle, and snap when bent; they are also easily
snapped from the branches.
The single specimen in the garden has made vigorous growth and promises
to do well under cultivation. It flowered in May of this year.
DESCRIPTION:--A branched herb up to 30 cm. high. _Branches_ cobwebby.
_Leaves_ 5·5 to 7·5 cm. long, 1 to 1·5 cm. broad above,
obovate-spathulate, narrowed into a petiole, pungent at the apex,
irregularly lobed, or toothed, with the lobes and teeth tipped with a
short pungent mucro, cobwebby above and beneath. _Flower-heads_ in the
axils of the leaves. _Peduncles_ slightly longer, as long as or shorter
than the leaves with tufts of cobwebby hairs. _Involucre_ 1·8 cm. long,
6 mm. in diameter below, the concrete portion oblong in outline,
inflexed at the base, sparsely cobwebby; outermost lobes 2·5 to 4 mm.
long, ovate, acute; inner lobes 1 cm. long, ovate, acuminate, acute,
with membranous margin. _Ray-florets_ neuter; tube 9 mm. long, somewhat
compressed; limb 1·6 cm. long, 7 mm. broad, obovate-elliptic, yellow,
with a black eye-spot. _Disc-florets_: tube 7 mm. long, cylindric; lobes
1·5 mm. long, oblong, shortly acuminate, subobtuse. _Anthers_ minutely
sagittate at the base. _Ovary_ very villous; style-branches linear,
obtuse. _Pappus_ of many delicate very narrow scales 5 mm. long.

On Plate 158 we figured a species _Lachenalia pendula_ belonging to the
same subgenus (_Eulachenalia_) as the species here described.
_Lachenalia rubida_ is a graceful little plant, though not so handsome
as some species of the genus. It was figured by Jacquin between the
years 1786-1793, from plants cultivated in Europe, so that it has been
known for over 130 years to botanists.
The species appears to be confined to the Clanwilliam, Calvinia and van
Rhynsdorp Districts of the Cape Province, and as far as our records go
does not appear to have been frequently collected.
We are indebted to Mrs. E. Rood of van Rhynsdorp for the specimens from
which our Plate was prepared.
