siettiana is assessed as Critically Endangered because its
extent of occurrence (EOO) is 0.0712 km² and its area of
occupancy (AOO) is less than 2 km². All the populations occur in
one location and there is a continuing decline in the quality
and extent of is habitat and in the number of subpopulations.
This species has been reintroduced into the island after
observing a 90% population reduction in the 1980s. The plant
grows in a very small area and population numbers fluctua
