Bryum species generally have shorter laminal cells with short, thick, and rounded stems. [3] All Bryum species exhibit narrowed cells at the margins. Bryum species can be identified through patterns of asexual reproduction , coloration features of the stem and leaf base, and the strength of the leaf border.
Moss is thought to add a sense of calm, age, and stillness to a garden scene. Moss is also used in bonsai to cover the soil and enhance the impression of age. [65] Rules of cultivation are not widely established. Moss collections are quite often begun using samples transplanted from the wild in a water-retaining bag.
In hornworts, the meristem starts at the base where the foot ends, and the division of cells pushes the sporophyte body upwards. In mosses, the meristem is located between the capsule and the top of the stalk (seta), and produces cells downward, elongating the stalk and elevating the capsule.
The polycomb gene FIE is expressed (blue) in unfertilised egg cells of the moss P. patens (right) and expression ceases after fertilisation in the developing diploid sporophyte (left). In situ GUS staining of two female sex organs (archegonia) of a transgenic plant expressing a translational fusion of FIE-uidA under control of the native FIE ...
Bryum argenteum, the silvergreen bryum moss or silvery thread moss, [1] is a species of moss in the family Bryaceae. It is one of the most common mosses of urban areas and can be easily recognized without a microscope.
Rhodobryum roseum, commonly known as rose moss, is a species of moss of the subclass Bryidae and family Bryaceae, found throughout most of the world in woods or sheltered grassy places. It rarely forms sporophytes and spore cases, and primarily reproduces vegetatively by stolons , horizontal stems that root at the nodes, resulting in ...
The GBIF also lists Morinia Cardot, [3] Saitoa, [4] Sebillea M.Bizot, 1974, [5] and Spruceella Müll.Hal., 1900 [6] but with no subfamily details.. Subfamily Timmielloideae (and its two genera of Timmiella and Luisierella) have been transferred to a new family Timmiellaceae, due to molecular phylogenetic analysis in 2014.
P. grandiglobum is a comose, medium-sized to robust moss with shoots that are approximately 10 mm tall, solitary or in loose colonies, bright yellow-green above and dark brown below . [3] The primary stem grows underground in a creeping fashion while sparse lateral branches and pale, smooth rhizoids grow from secondary branches. [ 1 ]
