These are the plants your grandchildren may never see.
The black-hooded sun orchid is critically endangered and found in only one location in NSW, at Botany Bay.
Fletchers Drumsticks is a shrub that grows on moist sheltered cliffs in the Blackheath area and is listed as threatened by root rot, disturbance by rock climbers and urban runoff. The white-flowered wax plant, a climber occurring on the edge of rainforest, is threatened by loss and fragmentation of habitat through agriculture and urban development.
In 95 per cent cases, it is human activity that is the cause of the threat, according to the Royal Botanic Gardens.
