very nearly related species close to P. punctatum, Thunb., and P.

This species is briefly referred to by Hook. Sp. Fil. iv. 262, where 
treated as an unrecognizable and therefore negligible synonym. Never- 
theless the original characterization is sufficiently detailed to show 
that the plant was distinct from any other Galapageian species unless 
it be P. paleaceum, Hook. f. The type will probably be found in the 
Darwin collection at the herbarium of Cambridge University.
