White Orthochilus leontoglossus flowers as seen here are common, as are the yellow ones. A faint pinkish tinge is present on some flowers in the pictured inflorescence, ivory on some others.
The mainly pendent flowers have erect bracts, small and pointed, while a larger stem leaf of similar shape is present below the flowers.
One doesn’t find this species in many plant books under its new name yet, the old one, Eulophia leontoglossa still being common. The taxonomic change only happened in 2014 when 34 Eulophia species were moved into the resurrected Orthochilus genus (Pooley, 1998; Lowrey and Wright, 1987; Wikipedia).
