Notes —See Gillespie (1993) for species discussion.

Müller cited the protologue of P. brachybotrya as “hb. Pavon! in hb. Boiss.” suggesting the holotype was a Pavon collection housed in Boissier’ s herbarium. Given that there is only one such sheet in Boissier’ s herbarium (now housed at G), we maintain that it is a holotype and not in need of lectotypification.
