Rossioglossum ampliatum (aka Oncidium ampliatum)
Oncidium ampliatum is now regarded to be a Rossioglossum - for the ones who know the other members of Rossioglossum this may seem to be a little bit odd. However, there have been reported hybrids between Oncidium (Rossioglossum) ampliatum and Rossioglossum grande, which emphasises that this taxonomical switch is correct. DNA studies have underlined this change.
It grows in Central America and Colombia, Ecuador, Peru and Venezuela.
