Sesleria

Sesleria

 

a genus of perennial plants of the family Grami-neae. The densely matted grasses have flat blades or blades that are folded lengthwise. The spikelets are for the most part two-or three-flowered and gathered in a dense spicate inflorescence.

There are about 40 species, distributed in Europe (mainly in the south) and, to a lesser extent, in Western Asia. In the USSR five or six species are found in the European part and in the Caucasus. S.phleoides and S. anatolica (formerly S. autumnalis), which grow on gravelly limestone slopes and cliffs in the alpine zone of the Caucasus, serve as pasturage for sheep and goats. S. coerulea grows in the mountains of Western Europe and on marshy meadows and bogs in the northwestern part of the European USSR. Some species of Sesleria are cultivated as ornamentals and for the production of dry bouquets.

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.

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 comosa, Sesleria latifolia and Festuca nigrescens.
