Leafing Fig Tree
Vernation (from ''vernal'' meaning ''spring'', since that is when leaves spring forth in temperate regions) is the formation of new leaves or fronds. In plant anatomy, it is the arrangement of leaves in a bud. In pine species, new leaves are short and encased in sheaths. Each leaf bundle consists of 2 to 5 needles. All the leaves on one section of branch grow in length together. In cabbage species, new leaves are folded over, each covered by the previous leaf. Circinate vernation Circinate vernation is the manner in which most fern fronds emerge. As the fern frond is formed, it is tightly curled so that the tender growing tip of the frond (and each subdivision of the frond) is protected within a coil. At this stage it is called a ''crozier'' (after the shepherd's crook) or ''fiddlehead'' (after the scrollwork at the top of a violin). As the lower parts of the frond expand and toughen up, they begin to photosynthesize, supporting the further growth and expansion of the frond. By ...

Temperate
In geography, the temperate climates of Earth occur in the middle latitudes (23.5° to 66.5° N/S of Equator), which span between the tropics and the polar regions of Earth. These zones generally have wider temperature ranges throughout the year and more distinct seasonal changes compared to tropical climates, where such variations are often small and usually only have precipitation changes. In temperate climates, not only do latitudinal positions influence temperature changes, but sea currents, prevailing wind direction, continentality (how large a landmass is) and altitude also shape temperate climates. The Köppen climate classification defines a climate as "temperate" C, when the mean temperature is above but below in the coldest month to account for the persistency of frost. However, other climate classifications set the minimum at . Zones and climates The north temperate zone extends from the Tropic of Cancer (approximately 23.5° north latitude) to the Arctic ...

Droseraceae
Droseraceae is a family (biology), family of carnivorous flowering plants, also known as the sundew family. It consists of approximately 180 species in three Extant taxon, extant genera. Representatives of the Droseraceae are found on all continents except Antarctica. Description Droseraceae are carnivorous plant, carnivorous herbaceous plants that may be annuals or perennials. Their leaves are alternate and Glossary of botanical terms#adaxial, adaxially Glossary of botanical terms#circinate, circinate, with at least one leaf surface containing hairs with mucilage-producing glands at the tip. Their flowers are bisexual, usually with three carpels and five sepals, petals and stamens. Their pollen grains are Glossary of botanical terms#triporate, triporate or multiporate and released in Glossary of botanical terms#tetrad, tetrads. Despite being carnivorous, their flowers are insect-pollinated, typically with white to purple flowers that close at night. They produce small see ...

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 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 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'. ''Calyx'' is derived from Greek 'bud, calyx, husk, wrapping' ( Sanskrit 'bud'), while is derived from Greek 'cup, goblet', and the words have been used interchangeably in botanical Latin. After flowering, most plants have no more use for the calyx which withers or becomes vestigial. Some plants retain a thorny calyx, either dried or live, as ...

Petal
Petals are modified Leaf, leaves that surround the reproductive parts of flowers. They are often advertising coloration, brightly colored or unusually shaped to attract pollinators. All of the petals of a flower are collectively known as the ''corolla''. Petals are usually accompanied by another set 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 Genus, genera such as ''Aloe'' and ''Tulipa''. Conversely, genera such as ''Rose, 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 colored tepals. Sinc ...

Aestivation (botany)
Aestivation or estivation is the positional arrangement of the parts of a flower within a flower bud before it has opened. Aestivation is also sometimes referred to as praefoliation or prefoliation, but these terms may also mean vernation: the arrangement of leaves within a vegetative bud. Aestivation can be an important taxonomic diagnostic; for example Malvaceae flower buds have valvate sepals, with the exception of the genera ''Fremontodendron'' and ''Chiranthodendron ''Chiranthodendron'' is a flowering plant genus in the family Malvaceae. It comprises a single species of tree, ''Chiranthodendron pentadactylon''. Names The tree is called the devil's, monkey's or Mexican hand tree or the hand-flower in English ...'', which have sometimes been misplaced as a result. Terminology The terms used to describe aestivation are the same as those used to describe leaf vernation. Classes of aestivation include: * ''crumpled'' * '' decussate'' * ''imbricate'' – overlapping ** ''co ...

Involute Vernation
Vernation (from ''vernal'' meaning ''spring'', since that is when leaves spring forth in temperate regions) is the formation of new leaves or fronds. In plant anatomy, it is the arrangement of leaves in a bud. In pine species, new leaves are short and encased in sheaths. Each leaf bundle consists of 2 to 5 needles. All the leaves on one section of branch grow in length together. In cabbage species, new leaves are folded over, each covered by the previous leaf. Circinate vernation Circinate vernation is the manner in which most fern fronds emerge. As the fern frond is formed, it is tightly curled so that the tender growing tip of the frond (and each subdivision of the frond) is protected within a coil.

Byblis (plant)
''Byblis'' ( ) is a small genus of carnivorous plants, sometimes termed the rainbow plants for the attractive appearance of their mucilage-covered leaves in bright sunshine. Native to Australia and New Guinea, it is the only genus in the family Byblidaceae. The first species in the genus was described by the English botanist Richard Anthony Salisbury in 1808. Eight species are now recognized (see below). ''Byblis'' species look very similar to ''Drosera'' and ''Drosophyllum'', but are distinguished by their zygomorphic flowers, with five curved stamens off to one side of the pistil. These genera are in fact not closely related; modern classifications place ''Byblis'' in the Lamiales, while the sundews and ''Drosophyllum'' are now placed in the Caryophyllales. Plant characteristics All species of the genus form upright growth supported by a weak, fibrous root system. The genus can be divided into two groups or "complexes": The ''B. liniflora'' complex and the ''B. gigantea'' c ...

Triphyophyllum
''Triphyophyllum'' is a monotypic plant genus, containing the single species ''Triphyophyllum peltatum'' of the family Dioncophyllaceae. It is native to tropical western Africa, in Ivory Coast, Sierra Leone and Liberia, growing in tropical forests. It is a liana, with a three-stage lifecycle, each with a different shaped leaf, as indicated by its Greek name. In the first stage, ''T. peltatum'' forms a rosette of simple lanceolate leaves with undulate margins. It then develops long, slender, glandular leaves, resembling those of the related ''Drosophyllum'', which capture insects; one to three of these leaves in each rosette. The plant then enters its adult liana form, with short non-carnivorous leaves bearing a pair of " grappling hooks" at their tips on a long twining stem which can become 165 feet (50 meters) in length and four inches (10 cm) thick. ''T. peltatum'' is the largest of all confirmed carnivorous plants in the world, but its carnivorous nature did not ...

Drosophyllum
''Drosophyllum'' ( , rarely ) is a genus of carnivorous plants containing the single species ''Drosophyllum lusitanicum'', commonly known as Portuguese sundew or dewy pine. In appearance, it is similar to the related genus ''Drosera'' (the sundews), and to the much more distantly related ''Byblis'' (the rainbow plants). Description ''Drosophyllum lusitanicum'' is a perennial carnivorous plant with woody stems at the base, short, simple or rarely branched, tortuous or erect. Leaves are basal in a dense rosette, sessile, linear, sheathed, circinate, covered with sessile and pedunculated glands. The caulines are sessile, alternate, the upper bracteiform. Flowers are on top, racemiform or corymbiform and bear five yellow petals. The flower calyx has five lobes and is late deciduous. The plant has ten stamens and introrsal anthers. Gynoecium has five carpels. It has five styles, simple; capitate stigma. Fruit is in a unilocular capsule, and is partially divided into five locules ...
