Odontoglossum halli Lindley 1837, in Ecuador
I saw this plant in the orchid house of the Botanical Garden of Quito, Ecuador. It is found in Colombia, Ecuador and Peru. This species is part of the Epidendroides group inside the group of orchids related to Oncidium.¹ There were plants of this species inside and outside the orchid house. The plant growing outside in the trunk of a tree, growing under shade had more flowers. The plant growing inside the orchid house was sitting in the ground and exposed to a much higher level of light. The flowers of the two plants I photographed were subtly different, the one outside had lips that were not flat, the one in the orchid house had a flat lip, the marking and the coloring of the flowers were also slightly different.
