It is also similar to A. capillaris (p. 639) and A. castellana (p. 639); it differs from both in its longer ligules, from A. capillaris in its less open panicles with spikelets near the base of the branches, and from A. castellana in being more extensively rhizomatous. The spikelets are yellowish, greenish, or purplish, and very narrow and pointed.

Anguina agrostis was one of the first plant parasitic nematodes to be taxonomically described by J.G. Inflorescence an open or contracted, usually much branched panicle of small spikelets. As a result, it is not expedient to discriminate the genetic resources of Agrostis capillaris according to geographic criterion. Agrostis x fouilladeana Lambinon et Verloove (A. capillaris x A. castellana) (Eur., N-Afr., W-As.) Uses. – Increasingly found naturalised in newly sown road verges, off-ramps and lawns, also in ruderal areas, dumps, coalmine heaps, sand-raised sites, railway yards and other man-made habitats.First reported from Roeselare in 1998 (Lambinon & Verloove 2000).

To examine putative specialization of a hemiparasitic plant to the most beneficial host species, we studied genetic variation in performance and trade‐offs between performance on different host species in the generalist hemiparasite, Rhinanthus serotinus.We grew 25 maternal half‐sib families of the parasite on Agrostis capillaris and Trifolium pratense and without a host in a greenhouse. Stolons absent, or present. Culms slender, erect or spreading. Spikelets often gaping, with 1 bisexual floret, on slender pedicels, disarticulating above or below the glumes, the spikelets or florets falling from the persistent inflorescence (Agrostis s.

Leaf-blades 1–15 cm long; 1–5 mm wide. caricinus Long Grey-beard Grass Amphipogon strictus var. Agrostis dubia DC. Agrostis capillaris, like many other members of the Agrostis genus are a valuable agronomic species because of their ability to produce fodder as well as provide food for grazing animals (APHIS, undated). INTRODUCTION Recent studies indicate that the selection pressures operating in natural populations can be much greater than the nominal values used in early models of natural selection constructed by … Agrostis capillaris is often referred to in many scientific articles and research as Agrostis tenuis.The accepted name according to ITIS is A. capillaris, while A. tenuis remains a synonym it is commonly found and incorrectly labeled as the primary name (ITIS, 2008).\r\n\r\n. 8 . The long, naked, straight and wiry inflorescence branches diverging at right angles are distinguishing.
