Hypericum aucheri, also known as Koramanotu in Turkish, [1] is a herbaceous perennial flowering plant in the St. John's wort family Hypericaceae.
H. aucheri was first described in Ill. Pl. Orient. by Hippolyte Jaubert and Spach in 1842. It is closely related to Hypericum thasium , but is smaller in all parts. Several variants were described by Jordanov & Kožukharov in 1970, but none of them seem to warrant taxonomic differentiation and are considered to be synonyms. However, a variant of the species found in the Kazdağ Mountains of Turkey called Hypericum kazdaghense may have enough distinctions from H. aucheri to warrant taxonomic consideration. These differences include amber instead of black anther glands, dichasial inflorescence, and different stem patterns. [2]
The species is a perennial herb that grows 9-35 centimeters tall, and either grows upwards or spreads across the ground. The species can have few or many stems that sometimes branch from the base and/or the upper stem nodes. These stems are narrowly 2-lined, with amber to reddish glands, and have internodes that are 4–25 mm long, and can be shorter or longer than the leaves. The leaves are sessile to subsessile and are ascending. They have 4-20 lamina (blades) that are each 1-6 mm long and are linear or elliptic; they are also slightly paler in color on the underside and are chartaceous. The laminar glands are pale, pointed, and densely placed; while the intramarginal glands are black, small, and few in number. The inflorescence is 50-flowered from 1–3 nodes, but can also flower from 1-3 lower nodes; the shape of the whole inflorescence is pyramidal to cylindric. The flowers are 12–18 mm in diameter; their buds are ellipsoid and acute. The sepals are equal and acute and measure 4–6 by 1–3 mm. The petals are bright yellow and 7–12 by 3–4 mm, and there are generally two petals for every sepal. There are 50-60 stamens, the longest of which are 5–10 mm and which have amber anther glands. The ovaries measure 1.5 by 1 mm and are ovoid, and there are 3 styles 3 that are 4 mm long and are diverging. [3]
The species can be found in Turkey, Greece, and Bulgaria. [4] In Greece, the species is native to the North Aegean Islands and North-East Greece. [5]
Hypericum is a genus of flowering plants in the family Hypericaceae. The genus has a nearly worldwide distribution, missing only from tropical lowlands, deserts and polar regions. Many Hypericum species are regarded as invasive species and noxious weeds. All members of the genus may be referred to as St. John's wort, and some are known as goatweed. The white or pink flowered marsh St. John's worts of North American and eastern Asia are now separated into the genus Triadenum.
Hypericum balearicum is a species of flowering plant in the family Hypericaceae, native to Spain's Balearic Islands. It is the only species in the section Psorophytum.
Hypericum mutilum is a species of St. John's wort known by the common name dwarf St. John's wort. It is native to parts of North America and is present in other parts as an introduced species. It is an annual or perennial herb taking a multibranched erect form up to about 60 centimeters tall. The oval green leaves are one or two centimeters long and are covered in tiny glands. The inflorescence is a compound cyme of tiny flowers. H. mutilum subsp. mutilum and subsp. boreale have a diploid number of 16, and H. mutilum subsp. boreale can have a diploid number of 18.
Hypericum olympicum, commonly known as the Mount Olympus St. John's wort, is a species of flowering plant in the family Hypericaceae found in the Balkans and Turkey and introduced to western Europe. It has been widely cultivated for centuries because of its large, showy flowers, which are far larger than those of most other species in Hypericum.
Hypericum terrae-firmae is a woody perennial flowering plant in the St. John's wort family Hypericaceae. It is an endemic plant species of Belize.
Hypericum punctatum, the spotted St. John's wort, is a perennial herb native to North America. The yellow-flowered herb occurs throughout eastern North America into southern Canada. The process of microsporogenesis carried out by this plant is prone to errors in chromosomal segregation. It has a diploid number of 14 or 16. Insects are attracted to the plant's pollen and the hypericin in the plant's leaves is toxic to mammals.
Hypericum cuisinii is a perennial herb in the genus Hypericum, in the section Adenosepalum. The herb has pale yellow flowers and occurs in Greece and Turkey.
Hypericum denticulatum, the coppery St. John's Wort, is a perennial herb in the flowering plant family Hypericaceae. It is native to the Eastern United States. The species has two varieties, H. denticulatum var. recognitum and H. denticulatum var. acutifolium. The herb has a diploid number of 24 or 48.
Hypericum majus, the greater Canadian St. John's wort, is a perennial herb native to North America. The specific epithet majus means "larger". The plant has a diploid number of 16.
Hypericum humboldtianum is a species of shrubby flowering plant in the St. John's wort family Hypericaceae native to Colombia and Venezuela.
Hypericum lancasteri, known as Lancaster's St. John's wort or as zhan e jin si tao in Chinese, is a species of flowering plant in the St. John's wort family Hypericaceae. The species has been awarded the Royal Horticultural Society's Award of Garden Merit.
Hypericum assamicum is a species of flowering plant in the St. John's wort family, Hypericaceae. It is endemic to India. Hypericum assamicum is one of two species of Hypericum in the section Hypericum sect. Sampsonia.
Hypericum sect. Sampsonia is a small section of plants in the genus Hypericum. It comprises only two species, both endemic to eastern Asia: Hypericum sampsonii and Hypericum assamicum.
Hypericum sechmenii is a rare flowering perennial herb in the genus Hypericum, in the section Adenosepalum, Hypericum huber-morathii group. The species is endemic to Eskişehir province, Turkey, and is most closely related to several other Turkish species of Hypericum.
Hypericum huber-morathii is a flowering plant in the family Hypericaceae, section Adenosepalum, and the type species of the Hypericum huber-morathii group.
Hypericum coris, the heath-leaved St. John's wort, also called yellow coris, is a species of flowering plant in the family Hypericaceae, and is the type species of sect. Coridium. It is a low shrub, and it is found in Switzerland and northwestern Italy. The species has been a popular garden plant since the 18th century, valued for its long flowering period and for how well it adapts to cultivation.
Hypericum harperi, the sharplobe St. Johnswort or Harper's St. John's wort, is a perennial flowering plant in the family Hypericaceae. It is an aquatic herb native to southeast North America. H. harperi has a diploid chromosome number of 24.
Hypericum vacciniifolium is a species of flowering plant in the flowering plant family Hypericaceae. It was first described by August von Hayek and Walter Siehe in the Ann. K. K. Naturhist. Hofmus. journal in 1914 from a specimen collected by Siehe in 1912.
Hypericum heterophyllum is a flowering plant in the Hypericaceae family and is the only species in Hypericum sect. Heterophylla.
