a plant that grows in sphagnum bogs. Oxylophytes include bog mosses, various heath shrubs, dwarf birch, low willows, crowberry, cloudberry, sundew, some sedges, cotton grass, and Scheuchzeria. Most plants in the group have pronounced xeromorphic characteristics. Xeromorphism is primarily due to the peat’s dryness, resulting from high acidity; low temperatures at the start of the growing season; and the peat’s high moisture capacity. Oxylophytes also have certain hydromorphic characteristics, such as highly developed, porous intercellular tissues. Many oxylophytes are psychrophiles.
