Aquilegia Micrantha Var. Mancosana
''Aquilegia micrantha'' var. ''mancosana'' is a perennial flowering plant in the family Ranunculaceae. The plant was discovered in 1891. It was first described by the American botanist Alice Eastwood as native to a single cavern of the Johnson Canyon in Ute Mountain Ute Tribe, Ute Mountain Tribal Park, Colorado, United States. Described as lacking nectar spurs something unusual among members of the ''Aquilegia'' (columbine) genus the plant was observed in the same location the next year. From then until the early 21st century, it had not been observed again in the wild and was presumed extinct. Despite this, it was still listed in Colorado flora (publication), floras. It has since been observed again at its original location. The taxonomic history of ''A. micrantha'' var. ''mancosana'' is unusual. It was initially described by Eastwood with the name ''A. ecalarata''. It was described as ''A. eastwoodiae'' and ''A. mancosana'' in 1902. In 1920, it was brief ...

Semiaquilegia
''Semiaquilegia'' is a genus of flowering plants of the family Ranunculaceae, native to eastern Asia. The genus was first proposed by the botanist Tomitaro Makino in 1902. Most authorities generally hold that there is only one species in the genus, '' Semiaquilegia adoxoides'', though other species have been proposed as members. The Royal Botanic Gardens, Kew's Plants of the World Online accepts four species of ''Semiaquilegia''. Description The genus ''Semiaquilegia'' are perennial herbaceous plants of the Ranunculaceae family. The plants possess tuberous roots. The arrangement of the leaves is basal (protruding from the stem's base) and cauline (attached to aerial stem). Some small leaves will grow on the flower stem during the early summer. ''Semiaquilegia'' plants flower, with flowers that are actinomorphic (possess radial symmetrical). These flowers possess five petaloid sepals and five petals. The petals are in a basally gibbous arrangement. There are 8 to 14 stamens. Cha ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Hermaphrodite
A hermaphrodite () is a sexually reproducing organism that produces both male and female gametes. Animal species in which individuals are either male or female are gonochoric, which is the opposite of hermaphroditic. The individuals of many taxonomic groups of animals, primarily invertebrates, are hermaphrodites, capable of producing viable gametes of both sexes. In the great majority of tunicates, mollusks, and earthworms, hermaphroditism is a normal condition, enabling a form of sexual reproduction in which either partner can act as the female or male. Hermaphroditism is also found in some fish species, but is rare in other vertebrate groups. Most hermaphroditic species exhibit some degree of self-fertilization. The distribution of self-fertilization rates among animals is similar to that of plants, suggesting that similar pressures are operating to direct the evolution of selfing in animals and plants. A rough estimate of the number of hermaphroditic animal species ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Anemone
''Anemone'' () is a genus of flowering plants in the buttercup family Ranunculaceae. Plants of the genus are commonly called windflowers. They are native to the temperate and subtropical regions of all regions except Australia, New Zealand, and Antarctica. The genus is closely related to several other genera including '' Anemonoides'', '' Anemonastrum'', '' Hepatica'', and '' Pulsatilla''. Some botanists include these genera within ''Anemone''. Description ''Anemone'' are perennials that have basal leaves with long leaf-stems that can be upright or prostrate. Leaves are simple or compound with lobed, parted, or undivided leaf blades. The leaf margins are toothed or entire. Flowers with 4–27 sepals are produced singly, in cymes of 2–9 flowers, or in umbels, above a cluster of leaf- or sepal-like bracts. Sepals may be any color. The pistils have one ovule. The flowers have nectaries, but petals are missing in the majority of species. The fruits are ovoid to obovoid sh ...

Clematis
''Clematis'' is a genus of about 380 species within the buttercup family, Ranunculaceae. Their garden hybrids and cultivars have been popular among gardeners, beginning with ''Clematis'' 'Jackmanii', a garden staple since 1862; more cultivars are being produced constantly. They are mainly of Chinese and Japanese origin. Species names Most species are known as clematis in English, while some are also known as: * traveller's joy, a name invented for the sole British native, '' C. vitalba'', by the herbalist John Gerard; * virgin's bower for '' C. terniflora'', '' C. virginiana'', and '' C. viticella''; * old man's beard, applied to several with prominent seedheads; * leather flower for those with fleshy petals; or vase vine for the North American ''Clematis viorna''. Etymology The genus name ''Clematis'' is from Ancient Greek κληματίς : ''clēmatís,'' ("a climbing plant") from κλήμα : ''klḗma'' – 'twig, sprout, tendril'. Botany The genus is composed of mostly ...

Isopyrum
''Isopyrum'' is a genus of flowering plants of the family Ranunculaceae native to Eurasia and North America. ''Isopyrum'' plants possess white flowers with five sepals and five petals. The genus was first described in 1753 by the biologist Carl Linnaeus. In 1920, the genus '' Paraquilegia'' was segregated out from ''Isopyrum'' to contain plants that are more morphologically aligned with members of the genus ''Aquilegia'' (columbines). Description ''Isopyrum'' is a genus of perennial herbs in the family Ranunculaceae. The smooth and glabrous stems stand erect. Leaves are biternate. The leaves attached to the base of the stem are pale green on the bottom and green on the top. Leaves attached to the stem have short petioles with white sheathes. Flowers on ''Isopyrum'' plants have radial symmetry. Each flower possesses five sepals and five petals. Sepals are white and petaloid. The petals are substantially smaller than the sepals. Each flower also features yellow anthers and between ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Petal
Petals are modified leaves that form an inner whorl surrounding the reproductive parts of flowers. They are often brightly coloured or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually surrounded by an outer whorl of modified leaves called sepals, that collectively form the ''calyx'' and lie just beneath the corolla. The calyx and the corolla together make up the perianth, the non-reproductive portion of a flower. When the petals and sepals of a flower are difficult to distinguish, they are collectively called tepals. Examples of plants in which the term ''tepal'' is appropriate include genera such as '' Aloe'' and '' Tulipa''. Conversely, genera such as '' Rosa'' and '' Phaseolus'' have well-distinguished sepals and petals. When the undifferentiated tepals resemble petals, they are referred to as "petaloid", as in petaloid monocots, orders of monocots with brightly coloured tepals. Since they ...

Sepal
A sepal () is a part of the flower of angiosperms (flowering plants). Usually green, sepals typically function as protection for the flower in bud, and often as support for the petals when in bloom., p. 106 Etymology The term ''sepalum'' was coined by Noël Martin Joseph de Necker in 1790, and derived . Collectively, the sepals are called the ''calyx'' (plural: calyces), the outermost Whorl (botany), whorl of parts that form a flower. The word ''calyx'' was adopted from the Latin ,Jackson, Benjamin, Daydon; A Glossary of Botanic Terms with their Derivation and Accent; Published by Gerald Duckworth & Co. London, 4th ed 1928 not to be confused with 'cup, goblet'. The Latin ''calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet'; both words have been used interchangeably in botanical Latin. Description The term ''tepal'' is usually applied when the parts of the perianth are difficult to distinguish, e. ...

Bulletin Of The Torrey Botanical Club
Torrey Botanical Society (formerly Torrey Botanical Club) was started in the 1860s by colleagues of John Torrey. It is the oldest botanical society in the Americas. The Society promotes the exploration and study of plant life, with particular focus on the flora of the regions surrounding New York City. Members of the group including Nathaniel Lord Britton and his wife Elizabeth Gertrude Britton founded the New York Botanical Garden. History The Torrey Botanical Society is an organization for people interested in plant life, including professional and amateur botanists, students, and others who simply enjoy nature. The society, which began informally in the 1860s under the aegis and inspiration of Columbia College Professor John Torrey, is thought to be the oldest botanical society in America. The early members were amateur botanists, students, and colleagues of Dr. Torrey, who were interested in collecting and identifying plants and occasionally met in the evening to discuss ...

Per Axel Rydberg
Per Axel Rydberg (July 6, 1860 – July 25, 1931) was a Swedish-born, American botanist who was the first curator of the New York Botanical Garden Herbarium. Biography Per Axel Rydberg was born in Odh, Västergötland, Sweden and emigrated to the United States in 1882. From 1884 to 1890, he taught mathematics at Luther Academy in Wahoo, Nebraska, while he studied at the University of Nebraska. He graduated from the University of Nebraska–Lincoln (B.S. in 1891) and (M.A. in 1895). He earned his graduate degree from Columbia University (Ph.D. in 1898). After he graduated, Rydberg received a commission from the United States Department of Agriculture to undertake a botanical exploration of western Nebraska. He received another one in 1892 to explore the Black Hills of South Dakota, and in 1893 he was in the Sand Hills, again in western Nebraska. During this time he continued to teach at the Luther Academy. In 1900 Rydberg conducted field work in southeast Colorado. In 190 ...

Petiole (botany)
In botany, the petiole () is the stalk that attaches the leaf blade to the Plant stem, stem. It is able to twist the leaf to face the sun, producing a characteristic foliage arrangement (spacing of blades), and also optimizing its exposure to sunlight. Outgrowths appearing on each side of the petiole in some species are called stipules. The terms wikt:petiolate, petiolate and wikt:apetiolate, apetiolate are applied respectively to leaves with and without petioles. Description The petiole is a stalk that attaches a leaf to the plant stem. In petiolate leaves the leaf stalk may be long (as in the leaves of celery and rhubarb), or short (for example basil). When completely absent, the blade attaches directly to the stem and is said to be Sessility (botany), sessile or apetiolate. Subpetiolate leaves have an extremely short petiole, and may appear sessile. The broomrape family Orobanchaceae is an example of a family in which the leaves are always sessile.

Flora Of North America
The ''Flora of North America North of Mexico'' (usually referred to as ''FNA'') is a multivolume work describing the native plants and naturalized plants of North America, including the United States, Canada, St. Pierre and Miquelon, and Greenland. It includes bryophytes and vascular plants. All taxa are described and included in dichotomous keys, distributions of all species and infraspecific taxa are mapped, and about 20% of species are illustrated with line drawings prepared specifically for FNA. It is expected to fill 30 volumes when completed and will be the first work to treat all of the known flora north of Mexico; in 2015 it was expected that the series would conclude in 2017. Twenty-four of the volumes have been published as of 2024. Soon after publication, the contents are made available online. FNA is a collaboration of about 1,000 authors, artists, reviewers, and editors from throughout the world. Reception The series has been praised for "the comprehensive treat ...
