Primula
''Primula'' () is a genus of herbaceous flowering plants in the family Primulaceae. They include the primrose ('' P. vulgaris''), a familiar wildflower of banks and verges. Other common species are '' P. auricula'' (auricula), '' P. veris'' (cowslip), and '' P. elatior'' (oxlip). These species and many others are valued for their ornamental flowers. They have been extensively cultivated and hybridised (in the case of the primrose, for many hundreds of years). ''Primula'' are native to the temperate Northern Hemisphere, south into tropical mountains in Ethiopia, Indonesia, and New Guinea, and in temperate southern South America. Almost half of the known species are from the Himalayas. ''Primula'' has over 500 species in traditional treatments, and more if certain related genera are included within its circumscription.''Primula''. ...

Primulaceae
The Primulaceae , commonly known as the primrose family (but not related to the Onagraceae, evening primrose family), are a family (biology), family of Herbaceous plant, herbaceous and woody flowering plants including some favourite garden plants and wildflowers. Most are Perennial plant, perennial though some species, such as Anagallis arvensis, scarlet pimpernel, are annual plant, annuals. Previously one of three families in the Order (biology), order Primulales, it underwent considerable genus, generic re-alignment once molecular phylogenetic methods were used for taxonomic classification. The order was then submerged in a much enlarged order Ericales and became a greatly enlarged Primulaceae ''sensu lato'' (''s.l''). In this new classification of the Angiosperm Phylogeny Group, each of the Prumulales families was reduced to the rank of subfamily of Primulaceae ''s.l.'' The original Primulaceae (Primulaceae ''sensu stricto'' or ''s.s.'') then became subfamily Primuloideae, and ...

Primula Vulgaris
''Primula vulgaris'', the common primrose, is a species of flowering plant in the family Primulaceae, native to western and southern Europe, northwest Africa, and parts of southwest Asia.''Flora Europaea''''Primula vulgaris''/ref> The common name is primrose,Natural History Museum''Primula vulgaris''/ref> or occasionally common primrose or English primrose to distinguish it from other ''Primula'' species also called primroses. None of these are closely related to the evening primroses (genus ''Oenothera''). Etymology The scientific name ''Primula'' is a diminutive of the Latin ''primus'', "prime", alluding to the fact that this flower is among the first to appear in spring. The vernacular name has the same meaning: primrose derives from a late Latin form ''prima rosa'', consisting of ''prima'', "first" (feminine), and ''rosa'', "rose". The Latin specific epithet ''vulgaris'' means "common", in the sense of "widespread". Description ''Primula vulgaris'' is a perennial growing ta ...

Primula Veris
''Primula veris'', the cowslip, common cowslip, or cowslip primrose ( syn. ''Primula officinalis'' ), is a herbaceous perennial flowering plant in the primrose family Primulaceae. The species is native throughout most of temperate Europe and western Asia, and although absent from more northerly areas including much of northwest Scotland, it reappears in northernmost Sutherland and Orkney and in Scandinavia. This species frequently hybridizes with other ''Primulas'' such as the common primrose ''Primula vulgaris'' to form false oxlip ( ''Primula'' × ''polyantha'') which is often confused with true oxlip (''Primula elatior''), a much rarer plant. Names The common name ''cowslip'' may derive from the old English for cow dung, probably because the plant was often found growing amongst the manure in cow pastures. An alternative derivation simply refers to slippery or boggy ground; again, a typical habitat for this plant. The name "cowslop" derived from Old English still exists in ...

Primula Auricula
''Primula auricula'', often known as auricula, mountain cowslip or bear's ear (from the shape of its leaves), is a species of flowering plant in the family Primulaceae, that grows on basic rocks in the mountain ranges of central Europe, including the western Alps, Jura Mountains, the Vosges, the Black Forest and the Tatra Mountains. Description It is an evergreen perennial growing to tall by wide. The leaves are obovate and stalkless, with a cartilaginous edge, all growing in a basal rosette, and sometimes covered in a mealy white bloom. The yellow flowers grow in clusters on long stalks. The specific epithet ''auricula'' means "ear-shaped", and refers to the shape of the leaves. Taxonomy A recent study split the species into two, '' Primula lutea'' and ''P. auricula'', with the former being found further south and east (Apennines, Carpathians, Balkans, and the southern and eastern Alps). Prior to this study, ''P. lutea'' had been considered synonymous with ''P. auricula' ...

Cortusa
''Cortusa'' is a formerly recognized genus in the family Primulaceae. It is now regarded as a synonym of the genus ''Primula''. It consisted of about 19 species of delicate, hardy, alpine perennials. The genus was named by the herbalist Matthiolus after his friend Cortusus, professor of botany at Padua, who discovered the plant originally called ''Cortusa matthioli'' (now ''Primula matthioli''. The plants are flowering herbaceous perennials native to the mountains of southern and eastern Europe, including the Alps and the Carpathians, with some species native to China. Most of the species are small spring bloomers for shade and rock garden. These low-growing and rather handsome little plants have clumps of downy, light green, heart-shaped leaves with serrated edges. In late spring, small loose umbel of delicate bell-shaped to lily-liked flowers born terminally on drooping spikes arise from the base, some 6-8in high. Flowers are magenta, pink, white and yellow. They are dormant in ...

Primula Elatior
''Primula elatior'', the oxlip (or true oxlip), is a species of flowering plant in the family Primulaceae, native to nutrient-poor and calcium-rich damp woods and meadows throughout Europe, with northern borders in Denmark and southern parts of Sweden, eastwards to the Altai Mountains and on the Kola Peninsula in Russia, and westwards in the British Isles. Description The oxlip is a herbaceous or semi-evergreen perennial plant growing to tall by broad, with a rosette of leaves 5–15 cm long and 2–6 cm broad. It produces light yellow flowers in spring, in clusters of 10-30 together on a single stem tall, each flower 9–15 mm broad. It may be confused with the closely related cowslip (''Primula veris''), which has a similar general appearance, although ''P. veris'' has smaller, bell-shaped, bright yellow flowers (and red dots inside the flower), and a corolla tube without folds. The leaves of ''P. veris'' are more spade-shaped than ''P. elatior''. Names T ...

Heterostyly
Heterostyly is a unique form of polymorphism and herkogamy in flowers. In a heterostylous species, two or three morphological types of flowers, termed "morphs", exist in the population. On each individual plant, all flowers share the same morph. The flower morphs differ in the lengths of the pistil and stamens, and these traits are not continuous. The morph phenotype is genetically linked to genes responsible for a unique system of self-incompatibility, termed heteromorphic self-incompatibility, that is, the pollen from a flower on one morph cannot fertilize another flower of the same morph. Heterostylous plants having two flower morphs are termed " distylous". In one morph (termed "pin", "longistylous", or "long-styled" flower) the stamens are short and the pistils are long; in the second morph (termed "thrum", "brevistylous", or "short-styled" flower) the stamens are long and the pistils are short; the length of the pistil in one morph equals the length of the stamens in the ...

The Different Forms Of Flowers On Plants Of The Same Species
''The Different Forms of Flowers on Plants of the Same Species'' is a book by Charles Darwin first published in 1877. It is the fifth of his six books devoted solely to the study of plants (excluding ''The Variation of Animals and Plants Under Domestication''). Context These writings contributed to Darwin's pursuit of evidence that would support his theory of natural selection. There were only two more books to follow: ''The Power of Movement in Plants'' (1880) and ''The Formation of Vegetable Mould through the Action of Worms'' (1881). He conducted a wide range of experiments and observations and the results of these form the framework of the book. He was assisted in this work by his son, Francis Darwin who also wrote a preface for the second edition which was published two years after his father's death in 1882. The book was dedicated to his longtime friend and colleague, Harvard botany professor Asa Gray "as a small tribute of respect and affection". The work Using the four c ...

Taxonomic Classification
In biology, taxonomy () is the scientific study of naming, defining ( circumscribing) and classifying groups of biological organisms based on shared characteristics. Organisms are grouped into taxa (singular: taxon) and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a more inclusive group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum (''division'' is sometimes used in botany in place of ''phylum''), class, order, family, genus, and species. The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a ranked system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With advances in the theory, data and analytical technology of biological systematics, the Linnaean system has transformed into a system of modern biological classification intended to reflect the evolut ...

Charles Darwin
Charles Robert Darwin ( ; 12 February 1809 – 19 April 1882) was an English naturalist, geologist, and biologist, widely known for his contributions to evolutionary biology. His proposition that all species of life have descended from a common ancestor is now generally accepted and considered a fundamental concept in science. In a joint publication with Alfred Russel Wallace, he introduced his scientific theory that this branching pattern of evolution resulted from a process he called natural selection, in which the struggle for existence has a similar effect to the artificial selection involved in selective breeding. Darwin has been described as one of the most influential figures in human history and was honoured by burial in Westminster Abbey. Darwin's early interest in nature led him to neglect his medical education at the University of Edinburgh; instead, he helped to investigate marine invertebrates. His studies at the University of Cambridge's Christ's Col ...

Linnaeus
Carl Linnaeus (; 23 May 1707 – 10 January 1778), also known after his ennoblement in 1761 as Carl von Linné Blunt (2004), p. 171. (), was a Swedish botanist, zoologist, taxonomist, and physician who formalised binomial nomenclature, the modern system of naming organisms. He is known as the "father of modern taxonomy". Many of his writings were in Latin; his name is rendered in Latin as and, after his 1761 ennoblement, as . Linnaeus was born in Råshult, the countryside of Småland, in southern Sweden. He received most of his higher education at Uppsala University and began giving lectures in botany there in 1730. He lived abroad between 1735 and 1738, where he studied and also published the first edition of his ' in the Netherlands. He then returned to Sweden where he became professor of medicine and botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 1760s, he continued to collect and ...
