Date Assessed: 2012-05-30
Assessor(s): Farjon, A.
Reviewer(s): Thomas, P., Perez de la Rosa, J. & Rushforth, K.
As this variety is known from only two localities with a very small area of occupancy, and as wildfires represent a credible threat, an assessment of Vulnerable under the D2 criterion is appropriate.
