P.S.Та же история по Roy Mottram:
«1980: Hunt (Cact. Succ. J. GB 42(4): 105-107) rejected Britton & Rose’s lectotypification of Echinofossulocactus Lawr. (1841) on grounds of mechanical selection and that the chosen type did not have the furrows called for by the protologue. The latter contention is, however, not true of mature plants, and none of the other many Britton & Rose selections have ever been rejected for mechanical selection.
1982: A proposal was made by Tjaden (Taxon 31(3): 570-573. (Aug) 1982) to conserve Stenocactus (K.Schum.) A.Berger over Echinofossulocactus Lawr.
1983: Tjaden’s proposal was opposed by Taylor (Taxon 32(4): 641-643. (Nov) 1983), pointing out that conservation is not required if Hunt’s relectotypification were to be followed.
1987: The Spermatophyta Committee (Taxon 36(4): 734-762. (Nov) 1987) rejected the Tjaden proposal with a 2-9 vote on the grounds outlined by Taylor. However, there never was a problem with the typification of Echinofossulocactus Lawr. by Britton & Rose in the first place.»
