6. An author can assert that synonymy exists between two concepts in separate classifications, or this can be assigned on the basis of shared circumscriptions (i.e. the similarity in the set of specimens included) (i.e. the case here with poyaensis) Because of the rules of nomenclature valid names might be shared between taxa that are not considered identical, and have different circumscriptions (the case here with rubricaulis). The Prometheus I/II integrated database holds data on described specimens and taxonomic hierarchies (and names, which can be calculated by the rules of priority etc.). Therefore it should be possible to base taxon circumscription on descriptive data (or ‘characters’). This will depend on collection of sufficient comparable high quality descriptive data.

7. Middleton’s distinction between A.rubricaulis and A.poyaensis (A.poyaensisis)... is close to A.rubricaulis but differs from it in the attenuate leaf base, the leaf blade apex always being mucronate even when the leaf is rounded, the fewer flowered inflorescences and the extremely flat peduncles by which it is most readily identified. Recorded evidence for this distinction Does Middleton consider deccurent to mean attenuate? mucronate is not a ‘distinguishing’ feature only one specimen is scored for this ‘distinguishing’ feature
