Neofinetia and Vanda falcata are the same plant!
Rhyncholaelia glauca and Rhyncholaelia digbyana are both fragrant as are their hybrids. Just a caution, not all orchid scents make the same impression on every body. To me glauca is fruity, digbyana smells like grapefruit to me, very citrus like.
Falcata to me is slightly fragrant. The other two above are strongly so.
Brassavolas are fragrant as the sun goes down. It's hybrids often carry that same scent of cheap perfume. Nodosa, perrinii, and cordata are fragrant.
Most Angraecum are fragrant, mostly at night. Many are pollinated by night flying moths and insects.
Oncidium Sharry Baby smells like chocolate.
A great many Cattleyas in general are fragrant.
I am growing about a dozen various Zygopetalum orchids. All are daytime fragrant. Some spicey, some fruity!
A good deal of Cycnoches, Catasetums, Mormodes and Clowesias are fragrant as are the hybrids.
