Chaenorhinum
''Chaenorhinum'' is a genus consisting of four species of annual and perennial herbs native to Turkey and the Mediterranean, where they thrive in dry stony areas and scree. They are closely related to snapdragons. The leaves are linear to oblong or rounded, opposite at the base. The flowers resemble snapdragons, being typically zygomorphic, hooded, lobed and spurred. They are borne in terminal racemes or singly in the leaf axils of the branching stems.

Chaenorhinum Minus
''Chaenorhinum minus'', also known as small toadflax in Europe and dwarf snapdragon in the US and Canada, is a very diminutive member of the plant family Plantaginaceae. It is native to continental Europe. Description ''Chaenorhinum minus'' differs from many toadflaxes in having alternate leaves growing singly. Its leaves and sepals are covered with glandular hairs. Leaves are glaucous and sepals are green or purple. Flowers vary from pale purple to white. It is an annual herb, with a maximum height of 25 cm. It does not spread vegetatively. Flowering occurs June–July.

Chaenorhinum Origanifolium
''Chaenorhinum origanifolium'' is a species of flowering plant in the family Plantaginaceae. It is native to mountainous regions of the Iberian Peninsula and the Balearic Islands The Balearic Islands ( es, Islas Baleares ; or ca, Illes Balears ) are an archipelago in the Balearic Sea, near the eastern coast of the Iberian Peninsula. The archipelago is an autonomous community and a province of Spain; its capital is .... It grows on rocks and crevices of escarpments, usually in limestone cliffs. Description ''Chaenorhinum origanifolium'' is a perennial herb, which reaches a size of up to 40 cm in height, non-cespitose, glabrous or glandular-pubescent in the lower third, densely glandular-pubescent in the upper part, with whitish appearance. Stems relatively thick and rigid to thin and flexuous, erect, ascending or prostrate, simple or branched from the base, purple at the base. Leaves of 4–23 × 2–13 mm, petiole 1.5–4.5 mm-, from suborbicular to oblan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plantaginaceae
Plantaginaceae, the plantain family, is a large, diverse family of flowering plants in the order Lamiales that includes common flowers such as snapdragon and foxglove. It is unrelated to the banana-like fruit also called "plantain." In older classifications, Plantaginaceae was the only family of the order Plantaginales, but numerous phylogenetic studies, summarized by the Angiosperm Phylogeny Group, have demonstrated that this taxon should be included within Lamiales. Overview The plantain family as traditionally circumscribed consisted of only three genera: ''Bougueria'', ''Littorella'', and ''Plantago''. However phylogenetic research has indicated that Plantaginaceae ''sensu stricto'' (in the strict sense) were nested within Scrophulariaceae (but forming a group that did not include the type genus of that family, ''Scrophularia''). Although Veronicaceae (1782) is the oldest family name for this group, Plantaginaceae (1789) is a conserved name under the International Code of B ...

Augustin Pyramus De Candolle
Augustin Pyramus (or Pyrame) de Candolle (, , ; 4 February 17789 September 1841) was a Swiss botanist. René Louiche Desfontaines launched de Candolle's botanical career by recommending him at a herbarium. Within a couple of years de Candolle had established a new genus, and he went on to document hundreds of plant families and create a new natural plant classification system. Although de Candolle's main focus was botany, he also contributed to related fields such as phytogeography, agronomy, paleontology, medical botany, and economic botany. De Candolle originated the idea of "Nature's war", which influenced Charles Darwin and the principle of natural selection. de Candolle recognized that multiple species may develop similar characteristics that did not appear in a common evolutionary ancestor; a phenomenon now known as convergent evolution. During his work with plants, de Candolle noticed that plant leaf movements follow a near-24-hour cycle in constant light, suggestin ...

Heinrich Gottlieb Ludwig Reichenbach
Heinrich Gottlieb Ludwig Reichenbach (8 January 1793 – 17 March 1879) was a German botanist and ornithologist. It was he who first requested Leopold and Rudolf Blaschka, Leopold Blaschka to make a set of glass marine invertebrate models for scientific education and museum showcasing, the successful commission giving rise to the creation of the Blaschkas' Glass sea creatures and, subsequently and indirectly, the more famous Glass Flowers. Early life Born in Leipzig and the son of Johann Friedrich Jakob Reichenbach (the author in 1818 of the first Greek-German dictionary) Reichenbach studied medicine and natural science at the University of Leipzig in 1810 and, eight years later in 1818, he the now Professor became an instructor before, in 1820, he was appointed the director of the Dresden natural history museum and a professor at the Surgical-Medical Academy in Dresden, where he remained for many years.

Snapdragons
''Antirrhinum'' is a genus of plants commonly known as dragon flowers, snapdragons and dog flower because of the flowers' fancied resemblance to the face of a dragon that opens and closes its mouth when laterally squeezed. They are native to rocky areas of Europe, the United States, Canada, and North Africa. It is widely used as an ornamental plant in borders and as a cut flower. Description The Antirrhinum is morphologically diverse, particularly the New World group (''Saerorhinum''). The genus is characterized by personate flowers with an inferior gibbous corolla. Taxonomy ''Antirrhinum'' used to be treated within the family Scrophulariaceae, but studies of DNA sequences have led to its inclusion in a vastly enlarged family Plantaginaceae, within the tribe Antirrhineae. Circumscription The taxonomy of this genus is complex and not yet fully resolved at present. In particular the exact circumscription of the genus, especially the inclusion of the New World species (Sae ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Floral Symmetry
Floral symmetry describes whether, and how, a flower, in particular its perianth, can be divided into two or more identical or mirror-image parts. Uncommonly, flowers may have no axis of symmetry at all, typically because their parts are spirally arranged. Actinomorphic Most flowers are actinomorphic ("star shaped", "radial"), meaning they can be divided into 3 or more identical sectors which are related to each other by rotation about the center of the flower. Typically, each sector might contain one tepal or one petal and one sepal and so on. It may or may not be possible to divide the flower into symmetrical halves by the same number of longitudinal planes passing through the axis: Oleander is an example of a flower without such mirror planes. Actinomorphic flowers are also called radially symmetrical or regular flowers. Other examples of actinomorphic flowers are the lily (''Lilium'', Liliaceae) and the buttercup (''Ranunculus'', Ranunculaceae). Zygomorphic Zygomorp ...
