Habitat Notes

Grows abundantly in association with Lomandra longifolia (sagg – namesake) in sparse woodland with old Eucalyptus viminalis, trees and scattered shrubs. This type of woodland has been greatly reduced since European settlement. Most abundant where ground is regularly disturbed and appears to overlap the area of greatest rabbit activity, while few or no plants are found elsewhere in the same habitat.

Seed Information

Seed Treatment Notes

Orchid seeds are very minute yellow, brown or blackish dust-like particles. Orchid seeds are produced within a capsule that splits at maturity and releases thousands to millions of seeds. Dispersed by wind and water and only germinate following infection of the embryo by a suitable mycorrhizal fungus. Very few seeds become mature plants.
