    i've noticed some oncidiums are fragrant when in direct sun, and not at all when shaded. but eventually the sun will burn them, so what do you do? my sharry baby and a few others are highly scented in the sun, and barely scented otherwise. bright light gets me slight frangrance... also watering has an effect. with some sun and recent watering, my sharry baby can perfume the whole apartment.

Seriously, look at ruler and check out how massive 8 inches truly is. This is just an example, though. I see this kind of nonsense everywhere. I just saw specs on a particular dendrobium that claimed the flowers were 3.5 to 4 inches. Again, look at ruler...a 4 inch Dendrobium flower simply doesn't exist, and if it did, it would be quite a new discovery to almost all of us.
    While some do over-state the flower size, however, Rossioglossum can easily have 6" plus flowers. Some Dendrobium have 4-5" flowers and that is common. Vanda flower can be as big as a 10"+ plate.

    When I was thinking about Vanda Rothschildiana hybrids, I put down the measurement of Paph. roths. My point is that not all big flowers come from Cattleyas. Individual culture will make a huge difference also. Modern hybrid Vanda with sanderiana in the blood can easily have flower bigger than 6".

Almost all well-bloomed plants of Dendrobium Gatton 'Sunray', pulchellum and good clones of anosmum var. superbum will have flowers above 10cm.
    I'm very well aware that Rossioglossums are large flowered Onicidiums. But did you have a ruler when you checked them out? I've seen them as well, in person and online, and I'd say 4 inches at a stretch. People don't tend have a clear image of what half a foot (or more) truly is. It's very easy to exaggerate an inch or two, be it by mistake or otherwise, but it makes all the difference. 2 inches is quite a lot in flower terms.

    Very interesting thread. The biggest 'dinner plate' vanda I've seen were about 5 inch 'saucers' (and I've seen a fair number of vandas in my time). I have a 7inch Blc King of Taiwan but was told that they reach 9 inches in Taiwan, My Blc Haadyai Delight varies between 3 1/2 - 6 inches. I've seen a Rossoglossum grande hybrid that was almost 5 inches and a Vuyl Cambria Plush that was 4 inches. Cultural conditions, the number of flowers, the age of a plant play a significant part in determining the size of the blooms. Yes i measured the aforementioned orchids.( I carry a small measuring tape which serves as key holder for my motorcycle keys).

    The biggest dendrobium I have is Den King Dragon cross which is 3 1/2 inches and looks like a small/medium size cattelya.
