Sigmatostalix uncinata is a recently described species from Ecuador. It is related to Oncidium and has the same growth habit, a single leaf at the top of an oval pseudobulb and the pseudobulb surrounded by several sheathing leaves. The plant is 12 cm tall and the flowers 2 cm. It seems to do well with my other cool-temperature orchids and is mounted on a small piece of tree fern. It seems to bloom every couple of months with two to three flowers per flower spike.
