Helianthemum oelandicum | |
Helianthemum oelandicum, commonly called hoary rockrose, is a low growing plant confined to rocky dry calcareous areas especially close to the sea.
The plant typically has a central stock from which numerous branches radiate horizontally or ascending. Stipules are absent and the small leaves (about 10mm long) are simple and green above but densely hairy and grey below which is a distinguishing characteristic in areas where H. nummularium is also present. [2]
The yellow flowers have 5 petals, free at the base and 5 sepals in cymes generally with 1 to 6 flowers in each cyme. [2]
It is restricted to dry limestone rocky areas. In Britain it is always close to the sea but in mainland Europe its range is restricted to the calcareous upland ranges such as the Alps. [3]
It occurs in several areas of Europe including France, Germany, Spain, Sweden and parts of north Africa and the eastern Mediterranean countries. In the British Isles it is very restricted in its distribution being limited to parts of the South Wales coastline and a few locations on Anglesey and the Great Orme. [4]
Hyacinthoides non-scripta is a bulbous perennial plant, found in Atlantic areas from north-western Spain to the British Isles, and also frequently used as a garden plant. It is known in English as the common bluebell or simply bluebell, a name which is used in Scotland to refer to the harebell, Campanula rotundifolia. In spring, H. non-scripta produces a nodding, one-sided inflorescence of 5–12 tubular, sweet-scented violet–blue flowers, with strongly recurved tepals, and 3–6 long, linear, basal leaves.
Filipendula ulmaria, commonly known as meadowsweet or mead wort, is a perennial herb in the family Rosaceae that grows in damp meadows. It is native throughout most of Europe and Western Asia. It has been introduced and naturalised in North America.
Geranium robertianum, commonly known as herb-Robert, red robin, death come quickly, storksbill, fox geranium, stinking Bob, squinter-pip (Shropshire), crow's foot, or Roberts geranium, is a common species of cranesbill native to Europe and parts of Asia, North America, and North Africa.
Centaurea scabiosa, or greater knapweed, is a perennial plant of the genus Centaurea. It is native to Europe and bears purple flower heads.
Eriophorum angustifolium, commonly known as common cottongrass or common cottonsedge, is a species of flowering plant in the sedge family, Cyperaceae. Native to North America, North Asia, and Northern Europe, it grows on peat or acidic soils, in open wetland, heath or moorland. It begins to flower in April or May and, after fertilisation in early summer, the small, unremarkable brown and green flowers develop distinctive white bristle-like seed-heads that resemble tufts of cotton; combined with its ecological suitability to bog, these characteristics give rise to the plant's alternative name, bog cotton.
Elodea canadensis is a perennial aquatic plant, or submergent macrophyte, native to most of North America. It has been introduced widely to regions outside its native range and was first recorded from the British Isles in about 1836.
Asarum europaeum, commonly known as asarabacca, European wild ginger, hazelwort, and wild spikenard, is a species of flowering plant in the birthwort family Aristolochiaceae, native to large parts of temperate Europe, and also cultivated in gardens. It is a creeping evergreen perennial with glossy green, kidney shaped leaves and solitary dull purple flowers hidden by the leaves. Though its roots have a ginger aroma, it is not closely related to the true culinary ginger Zingiber officinale, which originates in tropical Asian rainforests. It is sometimes harvested for use as a spice or a flavoring. In former days, it was used in snuff and also medicinally as an emetic and cathartic.
Cephalanthera longifolia, known by the common names narrow-leaved helleborine or sword-leaved helleborine or long-leaved helleborine, is a herbaceous perennial plant with rhizomes of the family Orchidaceae. It is native to light woodland, widespread across Europe, Asia and North Africa from Ireland and Morocco to China. This includes Iran, Russia, Kazakhstan, Turkey, Algeria, India, Pakistan, Germany, Italy, France, Spain, Portugal and many other countries.
A calcareous glade is a type of ecological community that is found in the central eastern United States. Calcareous glades occur where bedrock such as limestone occurs near or at the surface, and have very shallow and little soil development. Because of the shallow soil and the extreme conditions created by it, trees are often unable to grow in the glades. This creates a habitat that is usually sunny, dry, and hot. Calcareous glade vegetation is more similar to that of a desert habitat than a grassland, being dominated by small spring annuals with occasional geophytic or succulent perennials.
Rhododendron ponticum, called common rhododendron or pontic rhododendron, is a species of Rhododendron native to the Iberian Peninsula in southwest Europe and the Caucasus region in northern West Asia.
Geranium molle, the Dove's-foot Crane's-bill or Dovesfoot Geranium, is an annual herbaceous plant of the family Geraniaceae.
Honckenya peploides, the sea sandwort (UK) or seaside sandplant (Canada), is the only species in the genus Honckenya of the flowering plant family Caryophyllaceae. Other common names include sea chickweed, sea pimpernal, sea-beach sandwort, and sea purslane. The scientific name is often spelled "Honkenya", and is named after the German botanist Gerhard August Honckeny. This plant has a circumboreal distribution.
Dactylorhiza maculata, known as the heath spotted-orchid or moorland spotted orchid, is an herbaceous perennial plant of the family Orchidaceae. It is widespread in mountainous regions across much of Europe from Portugal and Iceland east to Russia. It is also found in Algeria, Morocco, and western Siberia.
Epilobium hirsutum is a flowering plant belonging to the willowherb genus Epilobium in the family Onagraceae. It is commonly known as the great willowherb, great hairy willowherb or hairy willowherb. Local names include codlins-and-cream, apple-pie and cherry-pie.
Lactuca muralis, the wall lettuce, is a perennial flowering plant in the dandelion tribe within the daisy family, also referred to as Mycelis muralis (L.) Dumort.
Asplenium trichomanes, the maidenhair spleenwort, is a small fern in the spleenwort genus Asplenium. It is a widespread and common species, occurring almost worldwide in a variety of rocky habitats. It is a variable fern with several subspecies.
Potamogeton pusillus is a species of aquatic plant known by the common names small pondweed, lesser pondweed or least pondweed. It occurs in standing and slow-flowing freshwater habitats throughout the Northern Hemisphere.
Rubus ulmifolius is a species of wild blackberry known by the English common name elmleaf blackberry or thornless blackberry and the Spanish common name zarzamora. It is native to Europe and North Africa, and has also become naturalized in parts of the United States, Australia, and southern South America.
Racomitrium lanuginosum is a widespread species of moss found in montane and arctic tundra across the Northern and Southern hemispheres. It grows as large mats on exposed rock and in boulder scree, particularly on acidic rocks. Its leaves have a characteristically decurrent and toothed hair-point, which gives rise to its regional common names woolly fringemoss, hoary rock-moss and woolly moss.
Euphorbia missurica, commonly called prairie sandmat, or Missouri spurge, is a species of flowering plant in the spurge family (Euphorbiaceae). It is native to North America, where it is found primarily in area of the Great Plains. Its natural habitat is in dry, often calcareous areas, including glades, bluffs, and open woodlands.
