Rhinanthus osiliensis (Ronn. et Saars.) Vassilcz. | |
Rhinanthus osiliensis, in English known by the common name Saaremaa yellow rattle, is a flowering plant in the genus Rhinanthus in the family Orobanchaceae. It is endemic to the Estonian island Saaremaa in the Baltic Sea. Plants growing on the Swedish island Gotland have been ascribed to R. osiliensis, too, but genetic analyses have not supported this hypothesis. [1] [2]
Morphological features of R. osiliensis include glandular hairs on the sepals (calyx) and relatively narrow leaves. It is a late-flowering species of Rhinanthus, flowering from the end of July onwards.
It grows in wet meadows and spring fens. [3] It is overall a rare species.
Saaremaa(also called Ösel [ˈøːsel] ) is the largest and most populous island in Estonia. Measuring 2,673 km2 (1,032 sq mi), its population is 31,435. The main island of the West Estonian archipelago, it is located in the Baltic Sea, south of Hiiumaa island and northwest of the Gulf of Riga. The administrative centre of the island, and of the Saare County, is the town of Kuressaare, which in January 2018, had 13,276 inhabitants.
Forsythia, is a genus of flowering plants in the olive family Oleaceae. There are about 11 species, mostly native to eastern Asia, but one native to southeastern Europe. Forsythia – also one of the plant's common names – is named after William Forsyth.
Antirrhinum is a genus of plants in the Plantaginaceae family, commonly known as dragon flowers or snapdragons because of the flowers' fancied resemblance to the face of a dragon that opens and closes its mouth when laterally squeezed. They are also sometimes called toadflax or dog flower. They are native to rocky areas of Europe, the United States, Canada, and North Africa. Antirrhinum species are widely used as ornamental plants in borders and as cut flowers.
Phoenix is a genus of 14 species of palms, native to an area starting from the Canary Islands in the west, across northern and central Africa, to the extreme southeast of Europe (Crete), and continuing throughout southern Asia, from Anatolia east to southern China and Malaysia. The diverse habitats they occupy include swamps, deserts, and mangrove sea coasts. Most Phoenix species originate in semi-arid regions, but usually occur near high groundwater levels, rivers, or springs. The genus is unusual among members of subfamily Coryphoideae in having pinnate, rather than palmate leaves; tribe Caryoteae also have pinnate or bipinnate leaves.
Alstroemeriaceae is a family of flowering plants, with 254 known species in four genera, almost entirely native to the Americas, from Central America to southern South America. One species of Luzuriaga occurs in New Zealand, and the genus Drymophila is endemic to south-eastern Australia.
Rhinanthus minor, known as yellow rattle, is a herbaceous wildflower in the genus Rhinanthus in the family Orobanchaceae. It has circumpolar distribution in Europe, Russia, western Asia, and northern North America. An annual plant, yellow rattle grows up to 10–50 centimetres (3.9–19.7 in) tall, with upright stems and opposite, simple leaves. The fruit is a dry capsule, with loose, rattling seeds.
Rhinanthus is a genus of annual hemiparasitic herbaceous plants in the family Orobanchaceae, formerly classified in the family Scrophulariaceae. Its species are commonly known as rattles. The genus consists of about 30 to 40 species found in Europe, northern Asia, and North America, with the greatest species diversity in Europe.
A parasitic plant is a plant that derives some or all of its nutritional requirements from another living plant. They make up about 1% of angiosperms and are found in almost every biome. All parasitic plants develop a specialized organ called the haustorium, which penetrates the host plant, connecting them to the host vasculature – either the xylem, phloem, or both. For example, plants like Striga or Rhinanthus connect only to the xylem, via xylem bridges (xylem-feeding). Alternately, plants like Cuscuta and some members of Orobanche connect to both the xylem and phloem of the host. This provides them with the ability to extract resources from the host. These resources can include water, nitrogen, carbon and/or sugars. Parasitic plants are classified depending on the location where the parasitic plant latches onto the host, the amount of nutrients it requires, and their photosynthetic capability. Some parasitic plants can locate their host plants by detecting volatile chemicals in the air or soil given off by host shoots or roots, respectively. About 4,500 species of parasitic plants in approximately 20 families of flowering plants are known.
Rhinanthus angustifolius, the narrow-leaved rattle or greater yellow-rattle, is a plant species of the genus Rhinanthus. It is an annual wildflower native to temperate grasslands in much of Europe, and north and central Western Asia. The yellow flowers are mostly visited by bumblebees.
Mangifera indica, commonly known as mango, is a species of flowering plant in the family Anacardiaceae. It is a large fruit tree, capable of growing to a height of 30 metres. There are two distinct genetic populations in modern mangoes – the "Indian type" and the "Southeast Asian type".
Constancea is a monotypic genus of flowering plants in the family Asteraceae containing the single species Constancea nevinii, which is known by the common name Nevin's woolly sunflower. It is endemic to three of the Channel Islands of California, where it grows in coastal scrub habitat. This is a small shrub or subshrub generally growing up to one or 1.5 meters tall, and taller when an erect form, with a branching, woolly stem. The whitish, woolly oval leaves may be up to 20 centimeters long and are divided into many narrow lobes with edges curled under. The inflorescence is a cluster of 10 to 50 or more small flower heads, each on a short peduncle. The flower head has a center of hairy, glandular, star-shaped yellow disc florets and a fringe of four to nine yellow ray florets, each about 2 millimeters long. The fruit is an achene a few millimeters long with a small pappus at the tip.
Viidumäe Nature Reserve is a nature reserve situated on Saaremaa in western Estonia, in Saare County.
Melampyrum arvense, commonly known as field cow-wheat, is an herbaceous flowering plant of the genus Melampyrum in the family Orobanchaceae. It is striking because of the conspicuous spike of pink or purple terminal bracts which includes the flowers.
Aureolaria virginica, the downy yellow false foxglove or downy oak leach, is a perennial forb native to the eastern United States and Canada, which produces yellow flowers in summer.
Dracophyllum arboreum, commonly known as Chatham Island grass tree and tarahinau (Moriori), is a species of tree in the heath family Ericaceae. Endemic to the Chatham Islands of New Zealand, it reaches a height of 18 m (60 ft) and has leaves that differ between the juvenile and adult forms.
Rhinanthus alectorolophus, the European yellow-rattle, is a plant species of the genus Rhinanthus, native to Europe.
Datisca cannabina, called false hemp, is a species of flowering plant in the genus Datisca, family Datiscaceae, native to the Aegean Islands, Crete, Cyprus, Anatolia, the Levant, the Transcaucasus, Iraq, Iran, Central Asia, Afghanistan, Pakistan, the western Himalayas and Nepal. It is one of the very few species known to have true androdioecy, meaning it has a mix of male and hermaphroditic individuals.
Dracophyllum traversii, commonly known as mountain neinei, grass tree, and pineapple tree is a species of flowering plant in the heath family Ericaceae. It is a deciduous tree endemic to New Zealand. It reaches a height of 0.2–13 m (0.66–42.65 ft) and has leaves which form tufts at the end of its branches. It has a lifespan of between 500 and 600 years.
