of this 'loss' of water in the

the survival of plant and animal

A small herb, this plant is
usually found as an understorey
plant in this region.
It grows in a range of habitats
throughout much of Australia.
The plant forms a rosette

The flower stalk can be up
to 50 centimetres long, but the
local form is shorter than this.
At the top of the stalk, a
hemispherical cluster of clear
blue flowers forms.
While each flower is quite
small, the number of them in
the cluster enables the plant to
be quite showy.
The plant can be propagated
from seed or by division of an

readily without pre-treatment,

old for a high germination rate
Life in cultivation tends to
be in the range of two to four

ON THURSDAY, July 10, members of the South
Australian Native Orchid Society under the
leadership of Joe Quarmby undertook the planting
of several Halbury greenhood orchids at Pengilly
This planting was done to extend the range of the species.
There are unconfirmed reports of the plant being found
naturally in Pengilly Scrub and the habitat is similar to Halbury.
Pengilly is a 19 hectare patch of mallee and sand dune
vegetation situated south of the town of Wasleys.
The reserve already has several species of orchids and
more than 100 native plant species, many of which are
This species of orchid (Pterostylis lepida) is classified
as critically endangered under the Commonwealth
Environment Protection Biodiversity Conservation Act
1999 and is considered to be restricted to two small sites
in South Australia.
According to the recovery plan for the species, there
are an estimated 9000 individual plants left at the known
The plant has a rosette of five to 10 ovate leaves and a
flowering stem from 10 to 30cm high.
The orchids are fragile and difficult to relocate.
The plants at Pengilly have been protected to deter
grazing and trampling.
Native Orchid Society members and Light Regional
Council and local conservationists will regularly monitor
the plants over the coming months and years.
