Comb Notchwort

<em>Sphenolobus minutus</em>, the comb notchwort, is a small leafy liverwort in the family Anastrophyllaceae, assessed as Least Concern on the IUCN Red List. It has a broad distribution across Europe and both North and South America, indicating a widespread presence in the Northern and Southern Hemispheres. As a liverwort, <em>S. minutus</em> belongs to the division Marchantiophyta and is among the earliest-diverging land plant lineages. It inhabits moist, shaded environments on decaying wood, mineral soil, and rock surfaces in forested and montane settings. The plant forms dense mats or patches of small, deeply lobed leaves arranged on a creeping stem, with lobes that may appear notched or comb-like in texture. Liverworts reproduce both sexually via spores and vegetatively via gemmae. <em>S. minutus</em> is sensitive to habitat moisture and atmospheric conditions, making it a potential bioindicator of environmental quality.
