Oeceoclades flavescens  Oeceoclades flavescens is a terrestrial orchid species in the genus "Oeceoclades" that is endemic to northeastern Madagascar. It was first described by the French botanists Jean Marie Bosser and Philippe Morat in 2001. The type specimen was collected in 1954 from the wet undergrowth of a coastal forest near Maroantsetra; it is the only known collection of this species. The specific epithet "flavescens" refers to the pale yellow flowers. The conical pseudobulbs are high and heteroblastic (derived from a single internode). The oblong to narrowly lanceolate leaves are long by wide, taper to a point, and have three to five primary longitudinal veins. There is a single papery leaf on each pseudobulb with a long petiole with a joint about below the leaf blade. Inflorescences are long, of which of that length is the peduncle. The inflorescence is a simple raceme with only 10 to 12 pale yellow flowers with purple streaks on the labellum. The sepals are long by wide and petals are long by wide. The four lobes of the labellum are rounded and the spur is forward-projecting. "Oeceoclades flavescens" is similar to "O. pulchra" but it is very distinctive in the papery leaves and the morphology of the labellum.
