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.
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.
2001), characterized by a diverse flora dominated by perennial grasses and other forbs such as Sesleria
achtarovii, Asperula aristata, Dianthus petraeus, Festuca ovina agg.
Tussock-forming graminoids Molinia caerulea, Carex davalliana, and Sesleria
DIAGNOSTIC TAXA OF THE ALLIANCE: Arabis collina, Arenaria bertolonii, Asplenium ruta-muraria, Sesleria
Biological flora of the British Isles: Sesleria

CLUSTER 4 corresponds to high-cover grasslands characterized by Sesleria
caerulea, Luzula pediformis, Polygonum viviparum and a total of 28 diagnostic (species (Table 1).
On plane or slightly inclined terrains the surface is covered by soil of up to 20 cm depth and provides opportunity for development of tussock grasses as for example Nardus stricta, Sesleria
latifolia and Festuca nigrescens.
