Note:
This extraordinary species was known only from the
type
locality Pella se Berge in Bushmanland in
Northern Cape
. A collection of an unidentified
Drimia
that was collected in leaf on the Koedoesberge near Touwsrivier in
Western Cape
has subsequently flowered in cultivation at Kirstenbosch National Botanical Gardens and clearly represents the same species, viz. 2 or 3 filiform leaves that are dry at flowering; diminutive inflorescence
30– 90 mm
tall with obscurely flecked, minutely striatepuberulous scape; nodding pedicels
4–6 mm
long at flowering [the dimensions of
12–15 mm
long at anthesis given in the protologue are clearly a mistake and refer to the elongated fruiting pedicels as is evident from Fig.
2 in
the protologue]; pendulous buff-coloured flowers with nocturnal anthesis and linear, revolute tepals ±
5 mm
long, connate at the base; only the three inner stamens developed, with filiform filaments ±
4 mm
long closely appressed to the ovary and style, and minute yellow anthers; narrowly subclavate style ±
2 mm
long and as long as the ovary; small subglobose capsules ±
4 mm
long; and elliptic, peripherally winged seeds ± 2.0–2.5 ×
1 mm
. This collection represents a range extension of some
200 km
south of the
type
locality.
