  1. Anyway I think we will not agree. Even a small explanation on the 2n = 64 of this taxon ? jeff
  2. it is not a joke , 'in situ' we can do without it for the species description also , may be for laboratory analysis and evenOther laboratory technician may very well. it is not a no-sense, the systematic and the clade system are not identical( see on the reptilian and the fish genus for example) ,and do not always make good household. here I think ,the melbourne code's must be use , like the IPNI . Anyway I think we will not agree jeff
  3. the caryotype and the morphologicals caracters For me botany is a whole, all the sciences must be joined: systematic, phylogenetic, caryology, palynology, study of the seeds, etc., none must have the predominance over the others why an hybrid in a consensus tree ?
  4. The author is always responsible for its publication, free to each to go in its direction or not In botany, as in other science, there is no single thought and fortunately. It needs to be peer-reviewed , why ? The forma taxa are highly polyphyletic. This is no more accepted as all taxa have to be monophyletic. Yes in the cladistic system, no in the evolutive systematic system jeff
  5. Bonjour Do you have evidence of your claims ? I do not see that on the last consensus tree,published, for apuana. jeff
  6. Bonjour Yes, but it can be published at any time if I want , I would always call it ,Even It displeases The notion of form is for me really real and must be taken into account, see the code of Melbourne and St louis : division II ,chapter I article 4 paragraph 4-1. the melbourne code's is always use by the IPNI JEFF
  7. for all my temperate and mexican calcareous ping I use cat liter 50% with some time akadama river sand 12.5% pouzzolane12.5% calcareous sand 12.5% vermiculite or perlite 12.5% jeff
  8. no difference it is the same . P.apuana 'in situ' in the alpes maritimes 2n=64 'in situ' in the alpi apuane 2n=64 where is the difference ? jeff
  9. for me a P.apuana not an hybrid jeff
  10. Bonjour yes it make hibernaculae in winter , for me it is a natural mutant to P. longifolia f longifolia . By seedling, the plants keep their darkred caracter. JEFF
  11. Bonjour 2 form actually in flower here on my calcareous wall in pot P.longifolia f longifolia P.longifolia f pinetensis ( perenn darkred leaves) JEFF
  12. Bonjour P.leptoceras f leptoceras P.corsica f corsica JEFF
  13. Bonjour use for the real colour a RHS fan like this https://www.azaleas.org/rhs-fan-2/ my P.mariae is near the RHS88C jeff
  14. have you the sepal form for the other ? P.vulgaris var alpicola is a geant form of P.vulgaris ,For my part I found them always at altitudes of + 1200 m, in grassy places and in the shade, closer to an ecotype than a variety in my opinion. for me the first is nevertheless quite close to a P. leptoceras f leptoceras jeff
  15. Bonjour see here one P.poldinii in my calcareous wall now the leaves are more grenat jeff
