Plant material front the Canary Islands similar to Plagiochila spinulosa (Dicks.) Dumort. has been identified as the Neotropical liverwort R stricta. Lindenb. The secondary metabolite profiles of CDCl3 extracts of both Neotropical and Macaronesian specimens of R stricta are distinct from those of R spinulosa in containing alloocimene and neoalloocimene as the principal monoterpenes rather than beta-phellandrene; the two species also show differences in the 9, 10-dihydrophenanthrenes and other aromatic compounds present. Phylogenetic analyses of ITS nrDNA sequence variation place P. spinulosa sister to P. stricta. Morphologically, P. stricta from Tenerife is distinguished most easily front P spinulosa by the scarcely decurrent antical leaf margin.
