i have puchased an orchid at a show and the name tag says

1576(Red Glory x Pulsar) X Charleswortharii (Floricultura)

i read a little on the name meanings and thought that i had it down until i read this one. can anyone shead some light on this for me? thank you in advance.

ps. i have no experience with Paphs so i "think" this is one. i could be wrong.
