Telipogon nigropurpureus (Orchidaceae: Oncidiinae): New insights on its morphology and distribution in Colombia and Ecuador

Over the past 20 years, Telipogon nigropurpureus had been known from only one specimen from the type locality near Arcabuco, Boyacá, in central Colombia. During botanical explorations in Colombia and Ecuador we have encountered more populations which are reported here. The new records found in Ecuador extend the known geographic range of T. nigropurpureus by 950 km south from the type locality. We provide an updated description, illustration, and photographs of the species, together with information on its ecology and distribution.
