nice plant, but it is not Stanleyi, and the pictured one is not a pure lueddemanniana (valid name) either. (speciossisima is a synonym for Lueddemanniana)
edit, this is the real Stanleyi , and it also matchs the painting that was done when the plant was awarded in 1901, by the RHS (if memory serves me well with the date)

what was said earlier is correct the plant pictured is likely the Cerro verde. or one of its many offprings.
i beleive the correct name for that plant would be C. carmen (lueddemanniana x warscewiczii) (google cattleya carmen)
