Question: Oeceoclades perrieri is an orchid that is native to the country bordered by what to the east?
Sentence (from "Oeceoclades perrieri"): When Leslie Andrew Garay and Peter Taylor resurrected and revised the genus "Oeceoclades" in 1976, these two taxa caused a naming conflict, so they chose to use "Eulophidium ambongense" as the basionym for "O. ambongensis" and reduced "Eulophia ambongensis" to a synonym of "O. perrieri", which was based on the basionym "Eulophidium perrieri" that Schlechter had also described later in 1925.
Relevant evidence: No
