Sue, it seems that your plant also produce a quite low densitiy of flowers per spike as mine... (if compared to standard equestris, or alba, or aurea or the clon 'Dark') am I right?
we have discussed here at the orchid society about this clon. We have two members specialized on Phals. The end of the discussion was that most of us agreed that this cannot me a pure equestris, but something back and back crossed... if you carefully check the flowers, you will also see differences with other equestris (and I know you have several
) In this clon you can even see a bit of the "denticulated" border of the petals, which is typical for hybrid plants with genetical incompatibility problems (like Paph. Wössner Bellarmi)
have you heard similar discussions about this plant?
