Colonial bentgrass

<em>Agrostis capillaris</em>, colonial bentgrass, is a perennial grass in the family Poaceae with an extensive native range across Europe and naturalised populations in North America, South America, and Oceania, including Australia and New Zealand. This species is highly adaptable, colonising tropical and subtropical moist broadleaf forests, temperate grasslands, disturbed soils, roadsides, and cultivated landscapes within the Neotropical realm. It is assessed as Least Concern by the IUCN. Colonial bentgrass is a fine-leaved, low-growing species often used in lawn and sports turf applications due to its tolerance for close mowing and its capacity to form dense, even swards. Its panicle inflorescences bear numerous small spikelets on delicate, hair-like branches, giving the species a feathery appearance when in flower. In its naturalised range, <em>Agrostis capillaris</em> can become invasive, competing with native grass species in acid grasslands and open heathlands. The species tolerates acidic and nutrient-poor soils, attributes that contribute to its widespread persistence in degraded landscapes. Biological traits of this species remain poorly documented in the scientific literature.

Comb windmill grass

<em>Chloris pectinata</em>, the comb windmill grass, is a grass in the family Poaceae with a distribution across Asia, Europe, and North America. It grows in disturbed and open habitats including roadsides, waste ground, dry grasslands, and agricultural margins, reflecting adaptability to degraded and human-modified environments. The genus <em>Chloris</em> is recognized by its distinctive windmill-like arrangement of spreading finger-like branches bearing one-sided rows of spikelets, which give the species an ornamental quality. The species epithet pectinata refers to the comb-like appearance of the inflorescence. <em>C. pectinata</em> is an annual or short-lived perennial grass that reproduces primarily by seed. It is adapted to dry, warm climates and tolerates poor soils. In some regions, it is considered a ruderal weed, while in others it may serve as a minor forage grass. Specific biological metric data are not available in the current record.
