Mnium hornum, also known by the common names horn calcareous moss or swan's-neck thyme-moss, is a species of moss in the genus Mnium . [1]

Contents

Description

The upright stems of swan's-neck thyme-moss are 2 to 4 cm tall. Leaves are 4mm to 8mm long, with a toothed border of long, narrow cells. The vein ends a slightly below the tip of the leaf. The lower part of the stem has small, narrow triangular leaves. Capsules are 5mm long, with a lid that narrows abruptly into a short point. The seta is between 2.5 and 5 cm long. [2]

Habitat

Swan's-neck thyme-moss is native to Europe and eastern North America. It is commonly found in damp woodland conditions, especially in acidic soil, such as oak-birch, beech and pine woodlands. It is found on the ground, logs, rocks, tree bases and along streams. [3]

Uses

In 2012, researchers in Serbia found that Mnium hornum could be used as a potential source of arachidonic acid. [4]

Thyme is the herb of some members of the genus Thymus of aromatic perennial evergreen herbs in the mint family Lamiaceae. Thymes are relatives of the oregano genus Origanum, with both plants being mostly indigenous to the Mediterranean region. Thymes have culinary, medicinal, and ornamental uses, and the species most commonly cultivated and used for culinary purposes is Thymus vulgaris.

<span class="mw-page-title-main">Moss</span> Division of non-vascular land plants

Mosses are small, non-vascular flowerless plants in the taxonomic division Bryophytasensu stricto. Bryophyta may also refer to the parent group bryophytes, which comprise liverworts, mosses, and hornworts. Mosses typically form dense green clumps or mats, often in damp or shady locations. The individual plants are usually composed of simple leaves that are generally only one cell thick, attached to a stem that may be branched or unbranched and has only a limited role in conducting water and nutrients. Although some species have conducting tissues, these are generally poorly developed and structurally different from similar tissue found in vascular plants. Mosses do not have seeds and after fertilisation develop sporophytes with unbranched stalks topped with single capsules containing spores. They are typically 0.2–10 cm (0.1–3.9 in) tall, though some species are much larger. Dawsonia, the tallest moss in the world, can grow to 50 cm (20 in) in height. There are approximately 12,000 species.

<i>Coleus amboinicus</i> Species of plant

Coleus amboinicus, synonym Plectranthus amboinicus, is a semi-succulent perennial plant in the family Lamiaceae with a pungent oregano-like flavor and odor. Coleus amboinicus is considered to be native to parts of Africa, the Arabian Peninsula, and India, although it is widely cultivated and naturalized elsewhere in the tropics where it is used as a spice and ornamental plant. Common names in English include Indian borage, country borage, French thyme, Indian mint, Mexican mint, Cuban oregano, soup mint, Vicks plant, Spanish thyme. The species epithet, amboinicus refers to Ambon Island, in Indonesia, where it was apparently encountered and described by João de Loureiro (1717–1791).

<i>Thymus serpyllum</i> Species of plant

Thymus serpyllum, known by the common names of Breckland thyme, Breckland wild thyme, wild thyme, creeping thyme, or elfin thyme, is a species of flowering plant in the mint family Lamiaceae, native to most of Europe and North Africa. It is a low, usually prostrate subshrub growing to 2 cm (1 in) tall with creeping stems up to 10 cm (4 in) long. The oval evergreen leaves are 3–8 mm long. The strongly scented flowers are either lilac, pink-purple, magenta, or a rare white, all 4–6 mm long and produced in clusters. The hardy plant tolerates some pedestrian traffic and produces odors ranging from heavily herbal to lightly lemon, depending on the variety.

<i>Tasmannia lanceolata</i> Species of shrub

Tasmannia lanceolata, commonly known as Tasmanian pepperberry or mountain pepper, is a shrub native to woodlands and cool temperate rainforest of south-eastern Australia. The shrub varies from 2–10 metres (6.6–32.8 ft) high. The aromatic leaves are lanceolate to narrow-elliptic or oblanceolate, 4–12 cm long, and 0.7–2.0 cm wide, with a distinctly pale undersurface. Stems are quite red in colour. The small cream or white flowers appear in summer and are followed by black, globose, two-lobed berries 5–8 mm wide, which appear in autumn. There are separate male and female plants.

<i>Polytrichum commune</i> Species of moss

Polytrichum commune is a species of moss found in many regions with high humidity and rainfall. The species can be exceptionally tall for a moss with stems often exceeding 30 cm (12 in) though rarely reaching 70 cm (27.5 in), but it is most commonly found at shorter lengths of 5 to 10 cm. It is widely distributed throughout temperate and boreal latitudes in the Northern Hemisphere and also found in Mexico, several Pacific Islands including New Zealand, and also in Australia. It typically grows in bogs, wet heathland and along forest streams.

<i>Spiranthes spiralis</i> Species of orchid

Spiranthes spiralis, commonly known as autumn lady's-tresses, is an orchid that grows in Europe and adjacent North Africa and Asia. It is a small grey-green plant. It forms a rosette of four to five pointed, sessile, ovate leaves about 3 cm (1.2 in) in length. In late summer an unbranched stem of about 10–15 cm (3.9–5.9 in) tall is produced with approximately four sheath-shaped leaves. The white flowers are about 5 mm (0.20 in) long and have a green spot on the lower lip. They are arranged in a helix around the upper half of the stalk. The species is listed in Appendix II of CITES as a species that is not currently threatened with extinction but that may become so. Autumn lady's-tresses are legally protected in Belgium and the Netherlands.

<i>Eucalyptus gomphocephala</i> Species of eucalyptus

Eucalyptus gomphocephala, known as tuart, is a species of tree, one of the six forest giants of Southwest Australia. Tuart forest was common on the Swan coastal plain, until the valuable trees were felled for export and displaced by the urban development around Perth, Western Australia. The wood is dense, hard, water resistant and resists splintering, and found many uses when it was available. Remnants of tuart forest occur in state reserves and parks, the tree has occasionally been introduced to other regions of Australia and overseas. Remaining trees are vulnerable to phytophthora dieback, an often fatal disorder, including a previously unknown species discovered during analysis of dead specimens.

<i>Allium triquetrum</i> Species of flowering plant

Allium triquetrum is a bulbous flowering plant in the genus Allium native to the Mediterranean basin. It is known in English as three-cornered leek, in Australia as angled onion and in New Zealand as onion weed. Both the English name and the specific epithet triquetrum refer to the three-cornered shape of the flower stalks.

<i>Hypnum cupressiforme</i> Species of moss

Hypnum cupressiforme, the cypress-leaved plaitmoss or hypnum moss, is a common and widespread species of moss belonging to the genus Hypnum. It is found in all continents except Antarctica and occurs in a wide variety of habitats and climatic zones. It typically grows on tree trunks, logs, walls, rocks and other surfaces. It prefers acidic environments and is fairly tolerant of pollution. It was formerly used as a filling for pillows and mattresses; the association with sleep is the origin of the genus name Hypnum.
