Galapagos Species Database

Taxon category: Accepted

previously misidentified as P. didactyla (originally reported by Weber 1986 as P. erumpens, later re-identified as P. spuria and subsequently cited by Elix & McCarthy as P. didactyla), the specimens are not tomentose and thus misidentifications of P. ulcerata Müll. Arg.

Origin: Native

Distribution: only known from only three historic specimens, Isabela (Sipman L-52) and Santa Cruz (L-40302, L-41144), no recent records; the species is an indicator of burned habitat, a common practice to clear the highlands for agriculture during Weber's visit of the archipelago, today no longer permitted
