Phlegmariurus mannii, synonym Huperzia mannii, is a species of lycopod,[2] known by the common names Mann's clubmoss and wawaeʻiole. It is endemic to Hawaii, where there are only six populations remaining.[3] It is a federally listed endangered species of the United States.

This plant is an epiphyte which grows upon other plants, especially koa (Acacia koa), ʻolapa (Cheirodendron trigynum), and kawaʻu (Ilex anomala).[4] 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.[4]

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.[3] Threats to its existence include damage to its habitat by feral pigs, cattle, and Introduced plant species, and the fact that there are few individuals remaining.[3][4]
