État de la populationTexte officiel évaluation IUCNExpert
In a demographic study, Perez-Farrera et al. (2006) estimated that there were four subpopulations comprising a total of 1,000-1,500 plants. Based on size classes, 40-45% were adults. Although the decline in one location has been 50%, the estimated decline across the total population is 20-30% within the past two generations (90 years).
