Thanks again. It's funny you know, when I bought it the grower told me that it was 'Yellow Cat', she made a point of telling me this. Now I'm really wondering what goes on here, perhaps they found a variation that stays more compact and yet produces a really big flower? Don't know if this happens in orchid culture, but it happens all the time in horticulture.
Sorry, but I haven't a picture of the whole plant, but it's very small compared to the size of the flower spike. I have to sit a rock on top of the pot or lean it against something to keep it from tobbling over.
