Silene acaulis, known as moss campion [2] or cushion pink, is a small wildflower that is common all over the high arctic and tundra and in high mountains of Eurasia and North America (Alps, Carpathians, southern Siberia, Pyrenees, British Isles, Iceland, Faroe Islands, Greenland, Rocky Mountains).
Leucobryum glaucum, commonly known as leucobryum moss or pin cushion moss, is a species of haplolepideous mosses with a wide distribution in eastern North America and Europe. [ 1 ] [ 2 ] [ 3 ] It inhabits temperate forests in the Northern Hemisphere, and its structure allows it to absorb metal ions.
The compact growth form of cushion plants reduces air flow over the surface of the epidermis, reducing the rate of water loss. Additionally, many cushion plants have small and fleshy leaves which reduce the surface area of the plant, which reduces transpiration and conserves water. In alpine environments well above the tree line, cold is a ...
New York City woke up to its first white Christmas in 15 years. But only a few areas of the U.S. are likely to see snow in the weather forecast for Christmas 2024.
The other major difference between tropical and arctic-alpine ecology is the temperature differences. The tropics have a summer/winter cycle every day, whereas the higher latitudes stay cold both day and night. In the northern latitudes, the main factor to overcome is the cold.
Phlox family (Polemoniaceae) perennials include dwarf phlox, or cushion phlox (Phlox condensata), which forms dense cushions plant with tiny branchlets only 1 inch (0.025 m) long, tiny leaves only 0.2 inches (0.0051 m) long and well adapted to resist the high winds, and flowers forming a nearly solid floral blanket of the underlying plant.

Leucobryum species are found in erect, dense, and often rounded cushions. Their color varies from white to grayish or bluish-green. Species are characterized by having thick, whitish leaves with a large, expanded costa. [1] It has been suggested that the characteristic pale color exhibited by some species is caused by air bubbles in the leucocysts.
