État de la populationTexte officiel évaluation IUCNExpert

The population of this species experienced rapid decline. Repeat helicopter surveys show numbers dropping from 677 in 1992 to 113 in 2001 (83% decline) and to 81 plants in 2004 (further 28%). S. Rogers (pers. comm.) from the Limpopo Provincial Government reported in 2006 that the species might be extinct in the wild as poaching had continued after 2004. Surveys in 2008 and then again in 2012 failed to locate any plants. Experts consulted during development of a management plan for the species agreed that it was most likely Extinct in the Wild but this needs to be confirmed by further surveys as there may be one remaining individual (S. Rogers pers. comm.).
