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.

common cow-wheat

<em>Melampyrum pratense</em>, commonly known as common cow wheat, is a semi-parasitic annual plant in the family Orobanchaceae. It is distributed across northern and central Europe, with occurrences recorded in Belgium, Denmark, Iceland, Norway, and Sweden, typically inhabiting ancient woodlands, heathlands, and species-rich grasslands. As a hemiparasite, common cow wheat attaches to the roots of neighboring plants via haustoria to obtain water and nutrients, while also conducting its own photosynthesis. It produces pairs of pale yellow tubular flowers with a closed mouth that are typically pollinated by bumblebees. The seeds of this species are attractive to wood ants, which disperse them through a process known as myrmecochory. <em>Melampyrum pratense</em> is assessed as Near Threatened on the IUCN Red List, reflecting ongoing habitat loss. Biological traits of this species remain poorly documented in the scientific literature.
