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

 prasinum, Baker.

 167; Anderss. (1), 128, & (2), 39. — James Isl.: Darwin, ace. to 

 Hook. f. (3), 167. Not secured by more recent collectors. Further 

 distrib. trop. Am. 



P. pleiosorum, Hook. f. (3), 166 (as ])Ieiosoros) ; Anderss. (1), 

 126, & (2), 38 (as Pleiosoros). — James Isl.: Darwin. Endemic. 

 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. loaleaceum, Hook. f. The type will probably be found in the 

 Darwin collection at the herbarium of Cambridge University.
