Sigmatostalix uncinata, from Ecuador, is a newly described species and is related to Oncidium. It was in fact first included in that genus. It is a small plant only 12 cm tall and looks like a fan of leaves with a small pseudobulb at the center of the leaves. It carries several flowers at a time on each flower spike and they continue to produce flowers for several months. The flowers are 2 cm and have a very prominent column which looks like a bird's head. The plant seems to do best for me mounted on a small piece of tree fern. It is one of around 70 species in a genus which ranges from Mexico to Brazil.
