Abstract Eleven species of
Carmichaelia retained high
seed viability for up to 24 years, linked with sustained impermeability of the
seed testa. Viable seeds germinated rapidly after scarification and showed no
specific light requirements. Shrub and dwarf shrub species retain high
viability after prolonged storage, whereas seeds of tree species had reduced
viability in older seeds. Long-term seed storage would be a suitable
ex
situ conservation tool for shrub and dwarf shrub species.
