On the right side:

Paphiopedilum Robin Hood (Sanders[St Albans] 1917) = Paphiopedilum Bingleyense × Paphiopedilum Gaston Bultel (syn Paphiopedilum Baron Schröder).

Paph. Gaston Bultel = Paph. fairrieanum x Paph. Oenanthum.
Paph. Oenanthum = Paph. Harrisianum × Paph. insigne
Nice! These are complex - yet familiar paphs.
