I don't know what the Vandas name is only know i swapped it for something with someone on the net in Australia. Others think its a vanda hybrid, maybe crossed with another orchid, a paravanda. It is pretty though.
My paph is Deperle alba im pretty sure. Which is Primulinum x delanatii. My guess is thats ts a multi- floral, producing multiple blooms on a spike that may open all at once. These may be from 2-13 flowers.
Or theres the sequential bloomers which open one flower at a time but as the first wilts the next opens and can bloom for a year.
And of cause the single flowers.
