Campylopus introflexus is a species of moss. It is native to countries in the southern hemisphere including New Zealand. It is a neophyte (a plant species recently introduced to an area) in Europe and coastal western North America where it has become invasive.
Individual plants measure 0.5–5 centimetres and have lanceolate (lance-shaped) leaves 4–6 mm. The plants are found in dense mats and are yellowish to olive green. The plant's midrib extends to form silvery hair like points which form an overhead layer that protects the plant from wind that would dry up its water reserves.
This species will sometimes reproduce asexually by means of stem tips that break off and are distributed by the wind. The can be multiple sporophytes in one plant.
