Vandaceous group
 

Where can I find a complete listing of all orchids that are considered part of the vandaceous group?

Your question isn't specific enough. From a botanical taxonomic perspective, family Orchidaceae is divided into multiple subfamilies, including Epidendroideae. That subfamily is divided into multiple tribes, including Vandeae. That tribe is subdivided into multiple subtribes.

Are you asking for all orchids closely related to genus Vanda, or do you also want those not so closely related? All the monopodial orchids I can think of, all of which are native to Asia and Africa, are in tribe Vandeae. I don't know of any monopodial orchids native to Europe, nor the Americas.

So in one sense, any monopodial orchid is vandaceous. But in another sense, orchids in subtribe Aeridinae, which includes Aerides, Phalaenopsis and Vanda, are more closely related than monopodial orchids in other subtribes, such as Angraecum. But I think most orchid growers consider Angraecum to be vandaceous.

Botanical sites tend not to be organized by tribes; rather, they are organized by genus and species. If you read through the genera at orchidspecies.com you will find subfamily, tribe and subtribe given in each genus listing. You will learn a lot doing this.

Question... what is the question that you're trying to answer with such a listing? Some of them interbreed and others don't. (For instance, the Angraecoids, mostly from Africa, are monopodial, could be considered Vandaceous, but they're genetically distinct from the Asian Vandas, and don't think that there are any hybrids between thw two groups.
