This handsome _Ornithogalum_ was collected by Mr. E. Rood at Van
Rhynsdorp, and forwarded to the Division of Botany, Pretoria. The
perianth segments are a deep reddish-brown, edged with white, and the
flowers are extremely fragrant. Specimens were sent to Kew, and the
Director reports that the plant had not been matched, the nearest
affinity being _O. suaveolens_, Jacq., and that it was evidently a new
species. This species exhibits a device for cross-pollination by the
movement of the style. As soon as the flower opens the style bends
downwards, and is thus in a position to receive pollen from the abdomen
of a visiting insect. As the flowers wither the perianth segments close
up, and the style becomes erect and would then be self-pollinated if
cross-pollination has not taken place.
DESCRIPTION:--_Bulb_ 2·2 cm. long, 2·8 cm. in diameter, globose, white.
_Leaves_ 3, up to 26 cm. long, 2·5 cm. broad at the base, lanceolate
(when opened flat), becoming deeply channelled above, acuminate,
clasping at the base, glabrous. _Peduncle_ up to 25 cm. long,
greenish-brown, glabrous. _Infloresence_ about 14-flowered, more or less
corymbose, 4 mm. long, about 6 cm. in diameter. _Bracts_ 1·4-2·5 cm.
long, ovate-lanceolate, acuminate into a long fine point, membranous,
as long as the pedicels. _Pedicels_ 1·1-2·5 cm. long, terete.
_Perianth-segments_ free to the base, spreading, 1·2 cm. long, 4 mm.
broad, oblong-lanceolate, dark purple with white margins, 5-nerved; the
outer cucullate at the apex with a fringe of short glandular hairs; the

long, 1·5 mm. broad in widest part, lanceolate, acuminate, more or less
compressed below, convex on both sides above; anthers 4 mm. long,
oblong, each lobe with a short beak. _Ovary_ 5 mm. long, 2·5 mm. in
