Rhizomes elongated. Resistance between species and between varieties of the same species of Agrostis varies considerably, however, it is generally accepted that A. tenuis is more susceptible to infection than A. canina or A. stolonifera (Gould et al., 1978; Smith, 1980).

Agrostis capillaris (Common Bent-grass) – Inflorescence a finely branched panicle of very small, 1-flowered spikelets and usually flat, glabrous and finely pointed leaf blades and (in A.capillaris) a short ligule, Awns in Agrostis are very variable and an unreliable character for distinguishing species. Seeds colonize recently disturbed sites with exposed mineral soil seedbeds [ 22 ].

Agrostis capillaris var. muelleriana Common Oak-bush Allocasuarina striata Stalked Oak-bush Amphipogon caricinus var. Agrostis capillaris L. APNI* . 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. Clive Stace, in New Flora of the British Isles (Second Edition), Cambridge University Press, 1997, lists eleven species of which the following six are likely to be met with in East Anglia : Agrostis capillaris, A. stolonifera, A. gigantea, A. vinealis, A.canina and September, 2011. Ligule an eciliate membrane; 0.5–2 mm long (shorter than wide); truncate. NameThatPlant.net currently features 3816 plants and 23,855 images. Inflorescence a panicle. Agrostis (bent or bentgrass) is a large and very nearly cosmopolitan genus of plants in the grass family, found in nearly all the countries in the world.

As a result, it is not expedient to discriminate the genetic resources of Agrostis capillaris according to geographic criterion. Culm-internodes smooth. Spikelets pedicelled. The inflorescence is a dense cylindrical panicle up to 12 centimeters long. – 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). However, the averaged values of the tested traits did not significantly differ between the countries, except for the inflorescence emergence date. Nr. 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. History and significance. 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. At some sites Agrostis capillaris was a minor component of otherwise indigenous vegetation; other sites were extensively modified. Image 5387095 is of colonial bentgrass (Agrostis capillaris ) flower(s). : Punctodera punctata We advise against extracting comparative information from the descriptions. Spikelets. SITE CHARACTERISTICS: Rough bentgrass occurs throughout a wide variety of habitats including woodlands, forest openings, grasslands, shrublands, meadows, swamps, bogs, marshes, and stream and lake … 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. caricinus Long Grey-beard Grass Amphipogon strictus var. Citation: L., Sp. Pl. Culms slender, erect or spreading. A. agrostis, is a serious pest of bentgrass (Agrostis spp.) Inflorescence branches: Ventenata dubia (North Africa grass); Vententata colonizes disturbed sites in open dry areas.
