Sanionia Moss (Sanionia uncinata)
Description
Sanionia uncinata forms loose, yellowish-green to brownish-green, shining lawns with 5 to 10 centimeters of long-standing, ascending, firm and stiff, distracting stalks. Characteristic are the hook-shaped ends of the rungs and branches. In the area of --the sprout plants there are lanzettlich-pfriemlicher Paraphyllien . The stem cross-section has a small-cell central strand, the bark layer consists of approximately five rows of thick-walled bark cells and a single-layered hyaline outer cortex. The stalk-leaves are strongly crescent-one-sided, 3.5 to 5 millimeters long, deeply folded, and gradually drawn out from a broader base into a very long and filiform tip. The leaf base does not run down or barely on the stem. The leaf margins are flat and fine serrated, the leaf rib extends to the leaf center or more frequently to the tip of the leaf. The laminacellas of the center of the leaf are narrow-linear, 5 -m wide and twelve to twenty times longer, the leaf base elongated-rectangular and spotted. In the leaf wings there is a small group of thin-walled, hyaline and dilated cells. Branch leaves are somewhat smaller, narrower and more curved than the stalks. The moss carries antheridia and archegonia on different branches on the same plant (autocotically), and frequently forms sporogons. The purple Seta is to 3 centimeters long, the capsule dual Peristom is cylindrical, inclined and curved, the conical cap is short bespitzt. The finely grained spores are 12 to 18 -m in size. Spore maturity is in spring and summer. Sanionia uncinata is a species rich in form. Particularly in higher mountain ranges, there are quite graceful forms, which are very similar to Ctenidium molluscum or Hypnum cupressiforme.
