Australia’s The Age reports that this pretty little orchid — Caladenia
robinsonii — is down to the last 20 plants in the wild.

plants in the wild.
The rest have fallen prey to bulldozers in their natural habitat
But at the Royal Botanic Gardens, staff have experienced
difficulties trying to save the delicate terrestrial orchid that
relies on a small wasp for pollination.
"The flower itself resembles a wasp, so it basically encourages
the wasp to mate with it," said Chris Jenek, the curator of the
terrestrial orchid collection.
Mr Jenek has had to pollinate the orchids by hand using
toothpicks, left – a feat he was unable to achieve last year
because they flowered at different times.
"This year I could do it as they flowered perfectly
Caladenia robinsonii is one of three threatened species
of Victorian orchids at the centre of conservation efforts by the
botanic gardens staff and National Herbarium scientists. They hope
to increase numbers, with the aim of reintroducing them to
