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 Bladder Moss

The common bladder moss (<em>Physcomitrium pyriforme</em>) is a small annual moss belonging to the family Funariaceae. It is classified as Least Concern on the IUCN Red List and is native to Europe and North America, with confirmed records from Luxembourg, Portugal, and the United States. <em>Physcomitrium pyriforme</em> typically colonizes disturbed, moist soils such as cultivated fields, riverbanks, and pond margins, where it forms low-growing green mats or cushions. The species is an ephemeral moss, completing its life cycle rapidly after disturbance events that expose bare soil. It is recognizable by its pear-shaped or inflated capsules borne on short setae, which give the species its common name. Spores are dispersed through the splitting of the capsule lid, and the plant often takes advantage of temporarily wet conditions for growth and reproduction. Biological traits of this species remain poorly documented in the scientific literature.
