]. The plant underwent a catastrophic decline of almost 95% between 1946 and 1956. The population has now started to recover as a result of natural resistance in part of the remnant population and intensive conservation efforts. Some of the causes of reduction are not reversible due to urbanization and habitat loss, but provided that the recovery is maintained, future re-assessments should result in downlisting. The plant is currently classified as 'Critically Endangered' in the IUCN Red List of Threatened Species(2011)[

Propagation
The seed requires a period of cold stratification. The seed has a hard seedcoat and can be very slow to germinate, requiring a cold period followed by a warm period and then another cold spell, each of 2 - 3 months duration[

Another possibility is to harvest the seed 'green' (when the embryo has fully formed but before the seedcoat has hardened). The seedlings can be potted up into individual pots when they are large enough to handle. Grow on in pots until large enough, then plant out in early summer. When stored dry, the seed can remain viable for several years[
