The sapling-ladder moss or sapling-like palm moss ( Climacium dendroides ) is a deciduous moss that is common in Central Europe and always occurs in very moist places. Since it is an almost unmistakable moss , it used to be pressed for teaching purposes and used for so-called moss pictures.
Occurrence
The sapling ladder moss is a deciduous moss that is quite common in wet meadows and swamps in Central Europe. It occurs secondarily in damp deciduous forests , on park meadows and rarely on rocks in damp locations. It is a lime- avoiding, nutrient-loving moss that is also often found together with Rhytidiadelphus squarrosus , Calliergonella species and Plagiomnium undulatum . In general, the moss is considered to be a human cultural follower . Originally it is said to have been native to alder forests .
features
The deciduous moss forms secondary ascending trunks, which are branched in a characteristic tree-like manner and can be up to 10 cm high. They arise from rhizome-like creeping main trunks. The light to olive green colored branch leaves are often a little wrinkled and have a distinct midrib that ends in front of the leaf tip. They are arranged like roof tiles, oval shaped and slightly serrated at the top. There are numerous paraphyllia between the branch leaves . There are also ovate-shaped lower leaves that stand on the lower part of the secondary stems. Miserable forms or very young shoots can be short-branched or unbeaten. Sporogons are relatively rare. However, they are heaped in groups on the trunk and emerge from the crown of the tree. The upright, cylindrically shaped capsules stand at the tip of a long, slightly bent seta . They have a double peristome .
