I purchased this as Bulbophyllum horizontale via Madagascar import of Louisiana Orchid Connection in March 2017 (a couple month ago). But it is obviously miss-ID'd. I went through the keys in Field Guid to the Orchids of Madagascar by Cribb and Hermans (in a hacky way). Information about Bulbophyllum (and orchids in general) from Madagascar is scarce, so I couldn't find many photos/illustrations/information of species listed in the field guide. But I think it is in section Ploiarium. Am I correct? It seems to be somewhat similar to B. aggregatum. The brief description in the field guide seems to be similar to this plant. Can anyone help me identify this species? Or if you know a good literature (website, books, primary literature) about Bulbophyllum from Madagascar, or a good person to contact, I would love to know.
