Why are the seeds of this species difficult? The seeds may have morphophysiological dormancy, which would have to be overcome before they will germinate.

This species is likely to have Orthodox seeds - dry to 15-20% eRH and store at -20ºC, or as cool as possible.
Germinate on sand at 30ºC.
The seeds of this species may be Morphophysiologically Dormant, where dormancy occurs if the embryo is retained within the seed. The seeds may need to experience several 'seasons' to allow the embryo to grow and develop, before germination will occur. Mimick the seasonal patterns of the species' native habitat to overcome physiological dormancy. Use a moist pre-chill or pre-heat treatment (depending on local climatic conditions), before germinating the seeds on sand at their optimum temperature. If this does not work, you can perform delicate surgery to enable the embryo to grow. Excise the tissue near the root tip.
