across different climatological regions except the polar regions, mostly in tropic to north temperate regions. The genus contains both aquatic and terrestrial species. The genus was named for their rostrate opercula. The type species of this genus is ''Rhynchostegium confertum'' (Dicks.) Schimp.

Etymology

The genus name comes from the Greek ''rhyncho-'' (beaked) and ''stegos'' (a lid), which refers to the rostrate operculum of the sporophyte.

History

The genus was first described by Bruch and

Wilhelm Philippe Schimper Wilhelm Philippe Schimper (January 12, 1808 – March 20, 1880, in Lichtenberg) was an Alsatian botanist with French, later German citizenship. He was born in Dossenheim-sur-Zinsel, but spent his youth in Offwiller, a village at the foot of the ...

in 1852.

Habitats

Terrestrial species of ''Rhynchostegium'' live in moist to wet or shaded habitats, on rock, soil, tree base, tree stem, and logs. Aquatic species live by or in running water, including streams, springs, rivers, beds of waterfalls, and seepy cliffs.

Morphology

Gametophyte

''Rhynchostegium'' are small to large mosses that form either loose tuft or extensive mats on the substrate, with irregular or regular branching. The younger plants are generally deep green or light green; aging plants could become whitish, brownish, or paler green. Stems are creeping and lack hyaloderm, with acute to acuminate pseudoparaphyllia. Stem leaves are erectopatent or erect. Branch leaves are similar in morphology to stem leaves but smaller and sometimes narrower. Leaves are commonly straightly to homomallously arranged; subimbricate, subcomplanate, or complanate arrangement are sometimes seen, especially in branch leaves. Leaf base, decurrent or not, varies from

The leaves have a single costa that generally smoothly ends 35-75% up the leaf, and more often in branch leaves in an abaxial spine. Leaf surfaces vary from flat to slightly concave and not to strongly longitudinally plicate, with little to some pores and linear laminal cells. Leaf margins are serrate to

Sporophyte

''Rhynchostegium'' are autoicous. Covered by a naked calyptra is a rostrate to long-rostrate operculum attached to a red-brown to brown, oblong-cylindric, weakly curved capsule, which is inclined or horizontal to a red-brown, smooth seta that has abruptly contracted perichaetial leaves at the base, with acumen straight to reflexed. An annulus separates the operculum. The peristome is xerochastic and perfect, which the red to orange-red exostomes have reduced trabeculae and cross-striolae at the base of the teeth; in rare cases the exostomes are narrow and yellow. The broadly or narrowly perforated endostomes and developed to vestigial cilia are supported by a low or high basal membrane. Spore diameters range between 9-16 μm.

Further study showed a minimal 3-hydroxy-β-ionone concentration of 1 μM for the inhibition of cress hypocotyl growth, and 3 μM for cress root growth, while the endogenous concentration. The presence of 3-hydroxy-β-ionone in their natural substrate and the growing medium suggested secretion to the environment, which may imply an important role of 3-hydroxy-β-ionone in competition with other plants and the forming of pure colonies.
