DESCRIPTION:--_Roots_ tuberous, sometimes up to 50 cm. in diameter.
_Stems_ striate. _Leaves_ 8 to 14 cm. long, digitately 3-to 5-lobed; the
middle lobe pinnatisect; the side lobes again lobed on one side only or
pinnatilobed, more rarely almost entire; the mid-rib prominent above and
beneath, and with two prominent glands on the upper side at base of the
lamina, and with glands beneath at the base of each leaf-segment,
glabrous; petiole 1·3 to 1·7 cm. long, 6 to 7 mm. broad, flat above,
convex beneath, glabrous. _Calyx-tube_ 1·5 cm. long, campanulate, 1 cm.
in diameter above, narrowing to 1·5 mm. in diameter at the base,
glabrous; lobes 7 cm. long, 5·5 mm. broad, ovate, obtuse, glabrous; two
lobes with entire, the other three with lacerated margins. _Petals_ 9
mm. long, 2·5 mm. broad at the widest part, obovate, acuminate, obtuse,
narrowed at the base, with shortly ciliated margins, 3-nerved.
_Filaments_ united at the base, 4 mm. long, linear, broadening at the
base; anthers 6·5 mm. long, 1·5 mm. broad, linear, falcate when seen in
side view. _Glands_ at base of filaments ·5 mm. long, more or less
quadrate. _Style_ 1 mm. long, bilobed at the apex. _Corona_ represented
by a fimbriated rim. _Fruit_ fleshy, 3·5 cm. long, 2·5 cm. in diameter.
_Female flower_ not seen. (National Herb. Pretoria, No. 2639.)

PLATE 114.
WACHENDORFIA PANICULATA.
_Cape Province._
HAEMODORACEAE. Tribe EUHAEMODOREAE.
WACHENDORFIA, _Linn._; _Benth. et Hook. f. Gen. Plant._ vol. iii. p. 673.
=Wachendorfia paniculata=, _Linn. Sp. Plant._ 59; _Fl. Cap._ vol. vi. p. 2.
This plant is popularly known as “rooi knol,” because of the deep red
colour of the tubers when cut, and it is also known as “Spinnekop blom,”
as the colour and marking of the perianth resemble that of some spiders.
The latter name is also applied to _Ferraria undulata_ (see Plate 66 for
an illustration of a species of the genus).
The species was known in England at least as early as 1767, as there is
a record of its introduction into Kew Gardens in that year. The dull
brown colour of the flowers, which is rare among South African plants,
does not make the plant a very ornamental object in gardens, but as the
plant is interesting botanically it should have a place in any
collection of the native flora.
The family _Haemodoraceae_ contains about 120 species, found principally
in Australia, but species are also known in North and South America and
in Asia. In South Africa the family is represented by less than 50
species, the largest genus being _Sansevieria_. The genus _Wachendorfia_
is known by only two species.
