Great photos! Yes, those are
Bletia purpurea... purple coloration will differ in different areas (though I do not know why). When I made the record for
Bl. purpurea in Sarasota County, there were an equal population of albino and purple forms. Many were deep purple, others were pink. Perhaps it is the pH that has an influence on the purple and pink, but I can't explain why there were so many albinos!
