Species description: Genus name is derived from the broad perforations in the ladder-like, inner-peristome teeth. Species name describing the treelike form of the plants.
Reproduction: Sporophytes infrequent except in floodplain areas where they are sometimes locally abundant in late winter and early spring; red-brown throughout.
Distinguishing characteristics: The miniature, tree-like plants that arise from a creeping stem are highly characteristic.
Habit: Forming loose, tall turfs of miniature trees that arise from creeping shoots; dark green to light green with reddish-brown stems. Habitat: Terrestrial or on logs (rarely on rock), in wet to marshy habitats, most luxuriant in areas subject to periodic flooding, from sea level to subalpine elevations; relatively widespread bur not common.
Similar Species: Although Leucolepis acanthoneuron has miniature treelike plants, these do not arise from a creeping shoot. The leaves of the main stem of L. acanthoneura are whitish and narrowly triangular while those of Climacium are heart-shaped and green. Sporophytes of Leucolepis are frequent in spring and sporangia are nodding, compared to the erect sporangia of Climacium.
Habitat / Range
Widely distributed in the Northern Hemisphere, extending in eastern North America southward to Wisconsin and Pennsylvania and in western North America to California; also in New Zealand.
