Galearis rotundifolia is a species of flowering plants in the orchid family, Orchidaceae. It is commonly called roundleaf orchid and small round-leaved orchid. It is a succulent perennial herb native to North America, where it occurs throughout Canada, part of the northern United States, and Greenland. [2] [1] [3]
Galearis rotundifolia is a succulent perennial herb growing from a fleshy rhizome. It reaches a maximum height around 33 centimeters. A single leaf clasps the base of the stem. It is variable in shape and size, reaching up to 11 centimeters in length. The inflorescence is a spike of flowers and leaflike bracts occupying the top of the stem. [3] The plant produces up to 18 flowers at a time. [4] The flower has six tepals in shades of white or light magenta; three are sepals up to a centimeter long, and three are shorter, narrower petals. The spurred, lobed lip of the middle petal is white with magenta spots and sometimes bars. Flowers bloom June to July. There are two pollinaria, which bear the sticky pollen. The fruit is a capsule. [3]
Galearis rotundifolia is native to northern North America, where it is widespread and most abundant at the northern latitudes. It occurs in nearly all of the provinces of Canada, Greenland, Alaska, and the northernmost contiguous United States, including Montana, Minnesota, Wisconsin, Michigan, Idaho, New York, Vermont, New Hampshire and Maine. [4] [5]
Galearis rotundifolia occurs in arctic and boreal climates. In the northern part of its range it is scattered in several habitat types, and in the southern part it is less common and mainly restricted to moist, shady areas. In the Rocky Mountains of Montana, Idaho and Wyoming, for example, it can be found along steams and in wet but well-drained limestone soils in shady spruce forests and woods. It is a glacial relict species. [4] [7]
The most important factor in appropriate habitat is a cold substrate. [4] In northern regions it can grow in full sun, while in southern areas it requires shelter. It is sometimes a dwarf plant in exposed areas on tundra. The substrate is usually also moist to wet, but not waterlogged. It is an obligate wetland species in southern areas, and a facultative wetland plant farther north. It also requires calcareous soils with a neutral pH, tolerating only slight acidity. [4]
Galearis rotundifolia usually reproduces sexually by seed, but it reportedly undergoes vegetative reproduction at times via rhizome or stolon, or perhaps when a ramet is separated from a clonal colony. [4]
The flowers are pollinated by insects. In a survey of pollinators in Alberta, the primary pollinator was Osmia proxima , a mason bee. Other pollinators included several hoverflies, such as Megasyrphus laxus , Eristalis hirta , Eristalis rupium , and Lapposyrphus lapponicus . The insects were observed probing the flower spur with their mouthparts and then getting the sticky pollen wads stuck on their heads as they pushed into the flower. [8] The tiny, light seeds are dispersed on the wind. [4]
Like other orchids, the plant has mycorrhizal associations with fungi in its root system. [4]
In general, Galearis rotundifolia is a widespread and secure species, especially in Canada. It becomes rare on the southern fringes of its range. Threats to the species include over-collection by orchid hunters and poaching of the plant for use as an herbal remedy. [4]
Orchids are plants that belong to the family Orchidaceae, a diverse and widespread group of flowering plants with blooms that are often colourful and fragrant. Orchids are cosmopolitan plants that are found in almost every habitat on Earth except glaciers. The world's richest diversity of orchid genera and species is found in the tropics.
Gymnadenia conopsea, commonly known as the fragrant orchid or chalk fragrant orchid, is a herbaceous plant of the family Orchidaceae native to northern Europe.
Campanula rotundifolia, the common 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.
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.
Drakaea is a genus of 10 species in the plant family Orchidaceae commonly known as hammer orchids. All ten species occur only in the south-west of Western Australia. Hammer orchids are characterised by an insectoid labellum that is attached to a narrow, hinged stem, which holds it aloft. The stem can hinge only backwards, where the broadly winged column carries the pollen and stigma. Each species of hammer orchid is pollinated by a specific species of thynnid wasp. Thynnid wasps are unusual in that the female is flightless and mating occurs when the male carries a female away to a source of food. The labellum of the orchid resembles a female thynnid wasp in shape, colour and scent. Insect pollination involving sexual attraction is common in orchids but the interaction between the male thynnid wasp and the hammer orchid is unique in that it involves the insect trying to fly away with a part of the flower.
Cephalanthera longifolia, the narrow-leaved helleborine, sword-leaved helleborine or long-leaved helleborine, is a rhizomatous herbaceous perennial plant in the family Orchidaceae. It is native to light woodland, and widespread across Europe, Asia and North Africa from Ireland and Morocco to China. This includes the United Kingdom, Iran, Russia, Kazakhstan, Turkey, Algeria, India, Pakistan, Germany, Italy, France, Spain, Portugal and many other countries.
Galearis is a genus of the orchid family (Orchidaceae) native to North America and eastern Asia. It contains about ten recognized species. The family name comes from the Greek word orchis ('testicle'), in reference to the shape of the root.
Galearis spectabilis, commonly known as showy orchis or showy orchid, is an orchid species of the genus Galearis. It is native to eastern Canada and much of the eastern half of the United States. In america they are found from eastern Oklahoma north to eastern South Dakota in the west and from Atlanta, Georgia and North Alabama north up into Maine to the east.
Geum triflorum, commonly known as prairie smoke, old man's whiskers, or three-flowered avens, is a spring-blooming perennial herbaceous plant of the Rosaceae family. It is a hemiboreal continental climate species that is widespread in colder and drier environments of western North America, although it does occur in isolated populations as far east as New York and Ontario. It is particularly known for the long feathery plumes on the seed heads that have inspired many of the regional common names and aid in wind dispersal of its seeds.
Erigeron peregrinus is a North American species of flowering plants in the family Asteraceae known by the common name wandering fleabane.

Penstemon grandiflorus, known by the common names shell-leaved penstemon, shell-leaf beardtongue, or large-flowered penstemon, is a tall and showy plant in the Penstemon genus from the plains of North America. Due to its large flowers it has found a place in gardens, particularly ones aimed at low water usage like xeriscape gardens.
Platanthera obtusata, common name blunt-leaved orchid or small northern bog orchid, is a small species of orchid in the genus Platanthera. It widespread across much of the colder regions of the Northern Hemisphere, though rare in some parts of its range. Two subspecies are recognized:
