Lepyrodon lagurus (Hook.) Mitt. is a member of the Bryophyta phylum, which encompasses all bryophytes, including mosses (Bryopsida class), liverworts, and hornworts. These ancient and resilient plants have been around for millions of years, predating even the earliest vascular plants.

Morphology and Identification

Lepyrodon lagurus (Hook.) Mitt. is a pleurocarpous moss, meaning its stems grow horizontally along the substrate. Its vibrant green hue and delicate, feathery appearance make it a true delight to behold. The leaves are ovate-lanceolate, tapering to a slender point, and arranged in a spiral pattern along the stem.
One of the most distinctive features of this moss is its double costa, or midrib, which extends beyond the leaf tip, forming a hair-like projection. This unique characteristic, along with its spirally twisted leaves, makes Lepyrodon lagurus (Hook.) Mitt. easily recognizable among its bryophyte brethren.

Global Distribution and Habitat

Lepyrodon lagurus (Hook.) Mitt. is widely distributed across various regions of the world, including
