Oncidium tenuoides

A cool-growing Andean orchid formerly called Odontoglossum tenue, renamed in 2008 when Odontoglossum was merged into Oncidium, since that genus already had an O. tenue. Herbarium records from southern Ecuador place it at 2500–2800 m in upper montane cloud forest. Grow it like other high-elevation odontoglossums: cool, bright-shaded, very humid and never dry.

Where it grows wild

Upper montane forest in the southern Ecuadorian Andes, for example around Yangana–Valladolid and the Cordillera Sabanilla above Amaluza. The labels give no habitat detail. Like most former Odontoglossum it is presumed to grow epiphytically in cloud forest.

Herbarium specimens range from 2500 to 2800 m.
