Tuberaria guttata, the spotted rock-rose or annual rock-rose, is an annual plant of the Mediterranean region which also occurs very locally in Wales and Ireland. The flowers are very variable with the characteristic spot at the base of the petal very variable in size and intensity of colour.
Tuberaria guttata is an annual plant that grows to 2–30 centimetres (1–12 in) tall. [3] It has a rosette of basal leaves, each up to 3 cm (1.2 in) long and 1.5 cm (0.6 in) wide, but this rosette has normally withered by the time the plant is in flower. The stems bear 2–5 opposite pairs of leaves, and a few smaller leaves higher up, arranged alternately. [3]
The inflorescence comprises around 12 flowers, 8–12 mm (0.31–0.47 in) in diameter. Each flower has five uneven sepals and five yellow petals usually with a dark red spot near the base. [3] The flowers are cleistogamous, [4] producing little pollen and no nectar, and attracting few insect visitors, [5] and the petals fall off after only a few hours. [3] The centre of the flower houses around 20 stamens and a single capitate stigma. [3]
The fruit of T. guttata is a capsule containing many seeds, each 0.6 millimetres (0.024 in) long. [3]
Tuberaria guttata is widely distributed in the Mediterranean region, and has a continuous distribution along the French Atlantic coast as far as the Channel Islands. [2] Further north, its distribution is very patchy, being confined to a few localities on the west coasts of Ireland and Wales. [2] The best-known of these populations is on the slopes of Holyhead Mountain in Anglesey. [2] These British populations mark the northernmost limit of the species' distribution. [2] Tuberaria guttata was chosen by Plantlife as the county flower of Anglesey in 2002. [6]
In California, T. guttata has become naturalised in the foothills of the Sierra Nevada on the eastern edge of the Sacramento Valley. [4]
In the Mediterranean region, T. guttata is common in arid habitats from woodlands to grasslands and roadsides. [5] In the British Isles, it grows "in bare patches of thin, dry soil overlying hard igneous rock in open areas within wind-cut heath near the sea". [7]
Tuberaria guttata was first described by Carl Linnaeus as "Cistus guttatus" in his 1753 work Species Plantarum . It was transferred to the genus Tuberaria by Jules Pierre Fourreau in 1868.
The Welsh populations were described as a separate species in 1844 by Jules Émile Planchon. He named the plants "Helianthemum breweri", after Samuel Brewer, who had discovered the population in 1726. [2] This is now considered a synonym of T. guttata. [2]
Ophrys apifera, known in Europe as the bee orchid, is a perennial herbaceous plant of the family Orchidaceae. It serves as an example of sexually deceptive pollination and floral mimicry, as well as of a highly selective and highly evolved plant–pollinator relationship.
Anacamptis pyramidalis, the pyramidal orchid, is a perennial herbaceous plant belonging to the genus Anacamptis of the family Orchidaceae. The scientific name Anacamptis derives from Greek ανακάμτειν 'anakamptein' meaning 'bend forward', while the Latin name pyramidalis refers to the pyramidal form of the inflorescence.
Centaurea cyanus, commonly known as cornflower or bachelor's button, is an annual flowering plant in the family Asteraceae native to Europe. In the past, it often grew as a weed in cornfields, hence its name. It is now endangered in its native habitat by agricultural intensification, particularly by over-use of herbicides. However, Centaurea cyanus is now also naturalised in many other parts of the world, including North America and parts of Australia through introduction as an ornamental plant in gardens and as a seed contaminant in crop seeds.
Glebionis segetum is a species of flowering plant in the family Asteraceae, probably native only to the eastern Mediterranean region but now naturalized in western and northern Europe as well as China and parts of North America. Common names include corn marigold and corn daisy.
Anemonoides nemorosa, the wood anemone, is an early-spring flowering plant in the buttercup family Ranunculaceae, native to Europe. Other common names include windflower, thimbleweed, and smell fox, an allusion to the musky smell of the leaves. It is a perennial herbaceous plant growing 5–15 cm (2–6 in) tall.
Campanula rotundifolia, the harebell, Scottish bluebell, or bluebell of Scotland, is a species of flowering plant in the bellflower family Campanulaceae. This herbaceous perennial is found throughout the temperate regions of the northern hemisphere. In Scotland, it is often known simply as bluebell. It is the floral emblem of Sweden where it is known as small bluebell. It produces its violet-blue, bell-shaped flowers in late summer and autumn.
Tuberaria is a genus of about 12 species of annual or perennial plants in the rockrose family Cistaceae, native to western and southern Europe. They occur on dry, stony sites, often close to the sea.
Anacamptis morio, the green-winged orchid or green-veined orchid, is a flowering plant of the orchid family, Orchidaceae. It usually has purple flowers, and is found in Europe and the Middle East.
Dianthus armeria, the Deptford pink or grass pink, is a species of Dianthus ("pink") native to most of Europe, from Portugal north to southern Scotland and southern Finland, and east to Ukraine and the Caucasus. It is naturalised in North America.
Lysimachia europaea is a flowering plant in the primrose family Primulaceae, called by the common name chickweed-wintergreen or arctic starflower. It is a small herbaceous perennial plant with one or more whorls of leaves on a single slender erect stem. It is about one third of a foot high (10 cm), giving it its generic name.? The broad lanceolate leaves are pale green but take on a copper hue in late summer. The solitary white flowers are reminiscent of small wood anemones and appear in midsummer. The fruits are globular dry capsules but are seldom produced.
Primula scotica, commonly known as Scottish primrose, is a species of flowering plant in the family, Primulaceae, the primroses and their relatives. It was discovered by James Smith, and is endemic to the north coast of Scotland.
Silene nutans is a flowering plant in the genus Silene, most commonly known as Nottingham catchfly.
Draba aizoides is a species of flowering plant in the family Brassicaceae, known as yellow whitlow-grass. It is native to Europe where it is found on limestone rocks and walls. In the British Isles it is found only on the Gower Peninsula in Wales.
Neotinea ustulata, the burnt orchid or burnt-tip orchid, is a European terrestrial orchid native to mountains in central and southern Europe, growing at up to 2,400 m (7,900 ft) elevation. The plant is considered Endangered in Great Britain and Least Concern internationally based on IUCN Red List criteria. The burnt-tip orchid was voted the county flower of Wiltshire in 2002 following a poll by the wild flora conservation charity Plantlife.
Helianthemum oelandicum, commonly called hoary rockrose, is a low growing plant confined to rocky dry calcareous areas especially close to the sea.
Gratiola amphiantha is a rare species of flowering plant known by the common names little amphianthus, pool sprite and snorkelwort. It was previously the only species in the monotypic genus Amphianthus, but it was moved to genus Gratiola after genetic analysis in 2008. It is native to the Piedmont region of the southeastern United States, with a center of distribution in Georgia. It occurs in Alabama and South Carolina as well. It is limited to granite outcrops, a high-biodiversity habitat type that is threatened by activities such as quarrying, off-road vehicles, and trash and debris dumping. It is a federally listed threatened species.
Samuel Brewer (1670–1743), was an English botanist and contemporary of Dr. Richard Richardson. He is credited with discovering certain species of plant.
Arenaria norvegica, also known as Arctic, English or Norwegian sandwort, is a low growing plant in the family Caryophyllaceae, found in northwest Europe. The chromosome number is 2n=80. There are two recognised subspecies.
Clegir Mawr is a Site of Special Scientific Interest (SSSI) in the community of Cylch-y-Garn in the north-west of the island of Anglesey, Wales. It is a stony coastal headland with an area just under 10 hectares and has been designated principally because of the occurrence of the spotted rock-rose which is a nationally rare plant and also the county flower of Anglesey.
Glannau Rhoscolyn is a Site of Special Scientific Interest in Anglesey, North Wales, and extends along the west coast of Holy Island, Anglesey for approximately 6.5 km. It has been designated as a Site of Special Scientific Interest since January 1961 in an attempt to protect its fragile biological and geological elements. The site has an area of 145.49 hectares and is managed by Natural Resources Wales.
