I should have gone to the Brazil plants for a start Myriam, I did think about it but didn't think he would be selling seeds of such a plant! I think I found another Aphelandra sp. on FloraSBS with similar shaped flowers but it was blue, a search brought me to the plantillustrations site. A long route after looking at other sites!
Mauro does list the location from which he collects seed, the differences suggest the species is variable.
