Dracaena
A shrub or small tree with a main stem
terminating in a rosette of elongate erect leaves, 30-50 cm long.
For a Dracaena it is unusual in growing in a fairly arid,
open habitat, with its distribution limited to the dry bushveld
escarpment of northern Mpumalanga and southern Limpopo provinces in
South Africa.
Identification
- Shrub or small tree, 2-5 m high.
- Leaves are greyish-green, leathery and strap-like, 30-50 cm
long by 3-6 cm wide, have a prominent midrib, and tend to be
erect not drooping.
- Bark is whitish to light brown with leaf scars.
- Flowers in sprays 15-20 cm long, greenish-white to cream and
20-25 cm long. They are sweet-smelling and open at night.
- Fruit are usually two lobed and are orange when mature.
Distribution and habitat
Distribution is limited to the escarpment in
northern Mpumalanga and southern Limpopo provinces, South Africa.
Unusual for a species of Dracaena in that it grows in arid
areas, on rocky mountain slopes and in open ravines.
Ecological interactions
- As the flowers are sweet-smelling and open at night, it is
likely that they are pollinated by moths, but there is no
evidence to support this.
Phenology
- Flowers from January to March.
- Fruits from March to June.
