 stalks grow either horizontally from the base of the plant or descend, often for great distances. A few species grow upright flower stalks. The long-tailed terminal flowers are basically triangular.

In general, though, if there is more than one flower bud on the raceme, they open up with long intervals. These flowers have a weird aspect, due to the long tails on each sepal
