>>>>>WHITE QUEEN is a cross from C. macowanii. Macowanii pollen actually sets seeds on 'White Queen.' Not many germinated, but I have one or two small seedlings from ['White Queen' x macowanii] growing. Hi Jim, Looks like White Queen is a polyploid, 2n = 44. The ref. for this polyploid 'White Queen' comes from KAVB and apparently it was bred by W. H. Henderson in 1930. White, waxy, with yellowish stripe on the reverse of the segments.
