This plant is an epiphyte which grows upon other plants, especially koa (Acacia koa), ʻolapa (Cheirodendron trigynum), and kawaʻu (Ilex anomala).[3] It has a hanging, branching, reddish stem no more than 10 centimetres (3.9 in) long. Each branch has three longitudinal rows of toothlike leaves. When reproducing the plant produces a branching fruiting spike which may be up to 20 centimetres (7.9 in) long.[3]
Today the plant is known from just a few occurrences on the islands of Maui and Hawaii. It is historically known from Kauai, but it may be extirpated there.[2] Threats to its existence include damage to the habitat by feral pigs, cattle, and introduced plant species, and the fact that there are few individuals remaining.[2][3]
