Morphological, anatomica, and physiological leaf trait plasticity of Sesleria
nitida (Poaceae) in open vs shaded conditions.
Leaf traits variation in Sesleria
nitida growing at different altitudes in the Central Apennines.
Studies on grasses such as Agrostis capillaries, Sesleria
caerulea, Calamagrostis varia etc., which are often found in Cd- Pb- and Zn-polluted mining soils showed high mycorrhiza infection between 50-81% (Leyval and Joner, 2001; Regvar et al., 2006).
According to TWINSPAN analysis, the data set was split into two major groups: (1) xerophytic to mesophytic communities of Sesleria
caerulea group (128 releves in total); and (2) mesophytic communities with Molinia caerulea or Carex hostiana as dominant species (53 releves in total).
Jundzill indicated: "We found very rare species and species which have never been found before, such as Callitriche intermedia, Circaea alpina, Circaea intermedia, Calamagrostis schleicheri, Koeleria cristata, Sesleria
caerulea, Scirpus caricinus, Primula farinosa, Salsola kali, Chenopodium villosum, Ribes alpinum, Swertia perennis, Lunaria rediviva, Alyssum montanum, Cakile maritima, Dentaria bulbifera, Taxus baccata, Betula nana, Myrica and many other cryptogams".
Such genera include Sesleria
, which has "bracts" in the lower part of the inflorescence that are generally interpreted as the glumes of sterile spikelets (Clayton & Renvoize, 1986), Coix, in which a highly modified leaf sheath forms a hard bead-like case around the pistillate spikelet (Jacques-Felix, 1961), and Lygeum, in which the parts of the spikelet are largely indistinguishable at maturity.
Above, timberline subalpine calcareous grasslands are well-developed (Karagiannakidou & al., 2001), characterized by a diverse flora dominated by perennial grasses and other forbs such as Sesleria
achtarovii, Asperula aristata, Dianthus petraeus, Festuca ovina agg., Carex halleriana, Festuca varia, Stipa pennata, Rostraria cristata, Vincetoxicum hirundinaria, Polygala nicaeensis, Scabiosa ochroleuca and others.
Tufts of blue moor grass (Sesleria
caerulea) fan out along the edge like sea anemones.
Tussock-forming graminoids Molinia caerulea, Carex davalliana, and Sesleria
(Chiarucci et al., 1998d) and a Sesleria
close to S.
DIAGNOSTIC TAXA OF THE ALLIANCE: Arabis collina, Arenaria bertolonii, Asplenium ruta-muraria, Sesleria
Caveat: This grass (Nassella tenuissima) can be invasive in some areas; if you live near parks or wild land, substitute Atlas fescue (Festuca mairei), autumn moor grass (Sesleria
autumnalis), blue grama (Bouteloua gracilis), or pink muhly (Muhlenbergia capillaris).
