Justification | Oxalis pseudo-hirta is known to occur at two sites where it was last seen in 1930. Both sites have been surveyed recently. The natural habitat at these sites has been transformed for vineyards and these subpopulations are locally extinct. Further searches of untransformed suitable habitat within this species' range are required before this species is listed as extinct. It is therefore listed as Critically Endangered Possibly Extinct. |
