features

Flowers of plants from the Sub-Adriatic Dinarides, Orjen in Montenegro

The Alps-sweet vernal grass is a perennial , herbaceous plant . It reaches a height of 15 to 20 (40) centimeters.

The leaf blade is rolled up tubular. The gray-green, matte upper side is not visible, only the shiny, yellowish-green underside.

The flowers are in panicles . These are one to two inches long and yellow to reddish brown. The lemmas of the fertile flowers are covered at the top with short bristle hairs and are therefore rough. The hairs of the two upper glumes do not reach the tip, which is often surrounded by a skin edge. Flowering time is from May to July. It spreads via epi zoochory and anemochory .

The species is diploid and one of the tribe of the common stalk grass . The number of chromosomes is 2n = 10.

Occurrence

the distribution area of ​​the alpine stony grass extends from Europe to Japan. It is distributed arctic-alpine. In Germany it occurs only in Bavaria (Alps, Bavarian Forest) and in Baden-Württemberg (Black Forest). It is quite common in Austria and Switzerland. In Austria it is only missing in Vienna, in the northern gneiss and granite country it is considered endangered.

The species grows in turf (especially bristle grass ) and dwarf shrub communities as well as in larch forests on moderately dry to slightly moist, poorly nutrient-rich, rather acidic soils. It thrives in plant communities of the associations Nardion strictae, Caricion fuscae and Caricion curvulae. The Alpine Ruchgras occurs in the (montane) subalpine to alpine altitude range , but mostly only above 1400 meters above sea level .

Taxonomy

Some authors (e.g. Flora of China) consider Anthoxanthum odoratum and Anthoxanthum nipponicum as subspecies of a species. Anthoxanthum nipponicum then receives the name Anthoxanthum odoratum subsp. nipponicum (Honda) Tzvelev (Syn .: Anthoxanthum odoratum subsp. alpinum (Á.Löve & D.Löve) BMGJones & Melderis ).
