Taeniophyllum clementsii

Taeniophyllum clementsii, commonly known as fleshy threadfoot, is a species of leafless epiphytic orchid which only grows as single plants. It has short stems and flattened green roots pressed against the tree on which it is growing. Between five and fifty small, pale green, tube-shaped flowers are arranged on a zig-zagged flowering stem. The flowers open one at a time, with the flowering stem increasing in length as each flower opens. This orchid only grows in a small area of tropical North Queensland....read more on Wikipedia.
