What are the morphological characteristics of this plant?

Plagiorhegma dubium has a prostrate, creeping growth habit characterized by small, translucent green leaves that are arranged in a single, irregular row along a thin stem. The leaves are typically ovate or elliptical in shape and possess a single, prominent midrib that extends toward the apex. These tiny, scale-like leaves are often closely overlapping, creating a dense, moss-like mat on its substrate. The stems are delicate and often branch irregularly, allowing the plant to spread across moist surfaces. This morphology is specifically adapted for colonizing thin layers of organic matter in humid environments.
