Black Bent

The Black Bent (Agrostis gigantea) is a species in the genus Agrostis. It is currently classified as Least Concern on the IUCN Red List. Inhabits tropical and subtropical moist broadleaf forests within the Neotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Common Pouchwort

The Common Pouchwort, <em>Calypogeia fissa</em>, is a liverwort in the family Calypogeiaceae, a group of non-vascular plants within the division Marchantiophyta. It is a leafy liverwort characterized by its creeping, pale green to yellowish shoots bearing overlapping, asymmetric leaves arranged in two lateral rows and a row of smaller underleaves. The species is typically found growing on moist, acidic soil, rotting wood, and shaded banks in temperate forests and moorlands. Its geographic range encompasses Asia, Europe, and North America, where it occupies humid woodland habitats and montane environments with stable moisture regimes. <em>Calypogeia fissa</em> reproduces both sexually via spores and vegetatively through gemmae, which are small propagules produced in specialized cups at shoot tips. As a bryophyte, it lacks true roots, stems, and leaves in the vascular sense, absorbing water and nutrients directly through its surface. The species is assessed as Vulnerable on the IUCN Red List, reflecting concerns about habitat loss and the degradation of moist woodland environments across parts of its range. Biological traits such as average lifespan, body size, and specific dietary preferences remain poorly documented for this species.
