The type specimen was collected in 1974 by Bosser and Morat from the woods near Ankazoabo, but it has also been found 40 km (25 mi) south of Sakaraha, near Mahaboboka, and near Morombe.

The specific epithet peyrotii was given to this species in honor of Dr. Jean-Pierre Peyrot whose observations and collections have led to a better understanding of Malagasy orchids.

Each pseudobulb has a single ovate-pointed, leathery leaf with slightly wavy margins.

The leaves are dark green on the upper surface and purplish on the underside, sometimes with darker stripes.

[2] Oeceoclades peyrotii is a terrestrial species found growing in deciduous forests of southwestern Madagascar, where it is known from only four locations.
