État de la populationTexte officiel évaluation IUCNExpert
It is estimated that there are approximately 2,000 mature individuals in the wild. The subpopulation at Once in Veracruz consists of 100 plants. The population has experienced significant declines over the past 50 years suspected to be 50-70% and even greater decline in habitat is projected over the next 20 years such that over a three generation period (90 years) the overall reduction is suspected to be at least 80%.
