Dryopteris remota (A. Br.) Hayek is regarded as a triploid apogamous species, perhaps a hybrid of ♀ D. assimilis Walker with ♂ diploid D. borreri Newm . The phloroglucides (phloroglucinol derivatives) of its rhizomes were investigated; their nature is compatible with the mentioned hypothesis. Besides several known compounds a new tricyclic phloroglucide C 36 H 44 O 12 , designated trispara‐aspidin was isolated. According to mass spectrum and products of reductive cleavage it has the structure given in formula 14 .
