Unknown Cattleyas in bloom

[Davesp310]

At least I think they are Cattleya's.

The one mounted on the tree branch is quite large, the blooms (there are 5 on a single spike) are maybe 3-4" across. The "canes" are around a foot tall or more, mostly topped with two leaves each (although some only have a single leaf). I have what I think is another specimen of this, growing in a pot, but it is a smaller plant (6" pot) and the flowers have a slightly smaller "purple" patch (will try to get a photo of it tonight)

The white one is slightly smaller, possibly 3" across the bloom, and an appropriatley smaller plant.

The red one is the smallest of the lot, it would only be 2" across, but it makes up in colour what it lacks in size.

The latter two both have two flowers on a single spike.

Once again, any thoughts would be appreciated as to what they are.

The white one looks like Cattleya intermedia

[euplusia]

The flowers are Cattleya type orchids.
The first one could be a walkeriana hybrid.
The second one might be a white intermedia or intermedia hybrid, so I second isurus.
The third red one would have obtained its colour from a Guarianthe aurantiaca or rupiculous Laelia like milleri.

They're all beautiful. Good growing.

possibly unknown identities....but appreciated none the less. The flowers are great!

They are beautiful cattleyas, second one possibly C intermedia, as suggested above.
