1. 'Red Leopard' (ventricosa x maxima)
2. Definitely a vent hybrid, a leaf shot might help.
3. x ventrata
4. x 'Miranda'
5. an x courtii form, probably with the northern purp
6. x catesbaei of some sort.
7. it has purp, leuco, and minor in it, but without having a definite label already you can't really give it one now. It's just a complex hybrid.
8 and 9, same deal, first has purp and rubrain it, but no label can be given, the next one leuco, minor, and possibly psittacina backgrounds, but it's an unknown hybrid.
10. Looks like excellens, but maybe mixed with rubra or alata as well.
11. definitely psittacina.
