David; The Iris society has many such hybrids. The primary cross is always a capital X and secondary parentages are small x's. generally the x before Chrysofor would be dropped and it would read 'Chrysofor' X Iris species using the cultivar name 'Chrysofor' which is synonymous with xChrysofor. Or you could have it written (I.chrysographes x I.forestii} X {I. sp.)presuming you know that chrysographes was the pod parent. Do a search on the Iris Encyclopedia under Species Crosses. at http://wiki.irises.org/bin/view/Main/Spx/WebHome/ ----- Original Message ----- From: "DAVID ROSS" <davidross350@btinternet.com> To: pbs@lists.ibiblio.org Sent: Tuesday, May 6, 2014 10:52:04 AM Subject: [pbs] Help with Nomenclature Dear All If you cross a hybrid for example Iris xchrysofor with another Iris species how do you name it - It seems wrong to call it Iris x chrysofor x (another species) - but I have no idea what is right.
