This is an unregistered cross between ( Cattleya forbesii x Laelia milleri ) x Guarianthe aurantiaca.
I picked it many years ago from a table with about 200 offsprings of this cross, flowering in many colours from white to yellow, rose, orange to red. Flower shape however was very uniform.
This is a robust temperature tolerant grower and winter bloomer. It does better when kept in a bright cooler part of the greenhouse at wintertime.
