The Haller or Haller MOORISH apple moss ( bartramia halleriana , . Syn : Bartramia norvegica . Lindb ) is a moss - kind from the family Bartramiaceae . The first description of the species (from 1768) comes from Albrecht von Haller , a Swiss doctor, botanist and science journalist who lived from 1708 to 1777.
features
Bartramia halleriana forms soft, green to brownish-green cushion lawns with plants up to 15 centimeters in size. The leaves with a weakly sheathed leaf base are drawn out in a long awl shape, up to 1 centimeter long, somewhat one-sided, wriggled dry and sawn in two rows at the edges. In contrast to Bartramia pomiformis , the leaves appear longer and more hair-shaped. The emerging leaf vein is serrated on the underside of the leaf tip. The lamina cells are elongated in the base of the leaf and are water-white, square to rectangular at the top and about 9 micrometers wide.
The spore capsules on the seta, which are up to 5 millimeters long, are more or less hidden in the moss lawn, with one to three sporogons emerging from a perichaetium.
Location claims and distribution
The moss avoids lime and grows in humid and mostly shady places in forests on rock and rock rich in bases or on humus over calcareous rock. In Central Europe it has its main distribution in the higher low mountain ranges and the Alps, in lower elevations it is rare or absent. In addition, it is more or less distributed almost worldwide, it is sighted in Europe, Asia, southern South America, Hawaii, Australia and New Zealand. Worldwide the species is not endangered (LC).
Canada
In Canada, this species was found only in western Canada. One of the locations is in Alberta in Jasper National Park and the other two just west of the same park in British Columbia . In 1826 it was sighted by Thomas Drummond on the Wood River , but has not been seen at this point since. In Alberta, in addition to the national COSEWIC classification as endangered, this moss is also in the highest endangered category of endangered plants (S1).
Studies at two of the documented sites revealed a population of 130 individuals (dumplings) with a total area of 116 cm².
DNA
In 2001, the mitochondrial DNA was sequenced at the University of Ulm . The nad2 gene ( NADH dehydrogenase subunit 2 ) was identified as a new locus marker for phylogenetic analyzes among early land plants.
