Notes
It is feasible that the criterium of the rachis structure used here for distinguishing subsp. coriacea from the exceedingly variable subsp. ensifolia is not entirely reliable. There are a few collections that match subsp. coriacea in other characters but have abaxially ± pronouncedly bi-angular axes.
