You guys are making my head spin with all the talk about parent identification, naming conventions, etc. HA! Even so, I truly appreciate the discussion as I am learning so much about my species orchids and primary hybrids.
My C. dolosa was tagged as (Cattleya loddigesii × Cattleya walkeriana) var. alba and is not nearly as old as Peter's stunning specimen. Here she is in bloom this past spring season.
