Cattleya alliance - possibly a common one

[Aussie42]

Hi all.

I suspect this is a common one as I have some identical flowers from a couple of plants I got from my grandmother's collection as well as a bunch in another collection I acquired. I have maybe 8 or more pieces of this, most quite large.

Its flowers start off slightly greenish - check out the last picture - and turn more lavender/purple as they age. FYI the third and fourth images are both flowers on the same plant, so there's no chance I got a touch of the sun, and the last one has only just opened whereas number 3 has been open for maybe a week.

Strong perfume, I'd say strongest in the mornings (but I only brought one inside this morning so I don't know if it's going to smell later tonight).

Any suggestions?

Cheers,
Aus.
