Heliotropium Ventricosum
''Heliotropium'' is a genus of flowering plants traditionally included in the family Boraginaceae ''s.l.'', but placed in the family Heliotropiaceae within the Boraginales order, by the Boraginales Working Group.. There are around 325 species in this almost cosmopolitan genus, which are commonly known as heliotropes. They are highly toxic to dogs and cats, as well as to humans.

Heliotropium Arborescens
''Heliotropium arborescens'', the garden heliotrope or just heliotrope, is a species of flowering plant in the borage family Boraginaceae, native to Bolivia, Colombia, and Peru. Common names also include cherry pie and common heliotrope. It is an economically damaging invasive species in Australia. Description Growing to tall and broad, it is a bushy, evergreen, short-lived shrub with dense clusters of bright purple flowers, notable for their intense, rather vanilla-like fragrance. Like many borage plants, the vanilla flower also contains poisonous pyrrolizidine alkaloids in addition to the fragrances. Cultivation As a perennial, it is hardy in zones 10 to 11, and requires wintering indoors in zones 9 or colder. It is hardy down to about . It can also be grown as a half-hardy annual (grown from seed under glass and planted out after all danger of frost has passed) in those areas. Alternatively soft-wood cuttings may be taken in summer. During the Victorian era in England th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clytie (Oceanid)
Clytie (; ) or Clytia (; ) is a water nymph, daughter of the Titans Oceanus and Tethys (mythology), Tethys in Greek mythology. She is thus one of the 3,000 Oceanid nymphs, and sister to the 3,000 River gods (Greek mythology), river-gods. According to the myth, Clytie loved the sun-god Helios in vain, but he left her for another woman, the princess Leucothoe (daughter of Orchamus), Leucothoe, under the influence of Aphrodite, the goddess of love. In anger and bitterness, she revealed their affair to the girl's father, indirectly causing her doom as the king Premature burial, buried her alive. This failed to win Helios back to her, and she was left lovingly staring at him from the ground; eventually she turned into a Heliotropium, heliotrope, a violet flower that gazes at the Sun each day in its diurnal journey. Clytie's story is mostly known from and fully preserved in Ovid's narrative poem ''Metamorphoses'', though other brief accounts and references to her from other authors su ...

Queen (butterfly)
The queen butterfly (''Danaus gilippus'') is a North and South American butterfly in the family Nymphalidae with a wingspan of . It is orange or brown with black wing borders and small white forewing spots on its Dorsum (biology), dorsal wing surface, and reddish ventral wing surface fairly similar to the dorsal surface. The ventral hindwings have black veins and small white spots in a black border. The male has a black androconial scent patch on its dorsal hindwings. It can be found in meadows, fields, marshes, deserts, and at the edges of forests. This species is possibly a close relative to the similarly colored soldier butterfly (or tropical queen, ''Danaus eresimus, D. eresimus''), in any case, it is not close to the plain tiger (''Danaus chrysippus, D. chrysippus'', African queen) as was long believed. There are seven subspecies. Females lay one egg at a time on larval host plants. Larvae use these plants as a food source, whereas adult butterflies feed mainly on nectar fro ...

Butterfly
Butterflies are winged insects from the lepidopteran superfamily Papilionoidea, characterized by large, often brightly coloured wings that often fold together when at rest, and a conspicuous, fluttering flight. The oldest butterfly fossils have been dated to the Paleocene, about 56 million years ago, though molecular evidence suggests that they likely originated in the Cretaceous. Butterflies have a four-stage life cycle, and like other holometabolous insects they undergo complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs out, expands its wings to dry, and flies off. Some butterflies, especially in the tropics, have several generations in a year, while others have a single generation, and a few in cold locations may take s ...

Pyrrolizidine Alkaloid
Pyrrolizidine alkaloids (PAs), sometimes referred to as necine bases, are a group of naturally occurring alkaloids based on the structure of pyrrolizidine. Their use dates back centuries and is intertwined with the discovery, understanding, and eventual recognition of their toxicity on humans and animals. History PAs were first discovered in plants in the 19th century, but their toxic effects were not immediately recognized. Instead, many PA-containing plants were traditionally used for medicinal purposes in various cultures around the world. For example, herbs containing PAs were used in traditional Chinese medicine and by Native American tribes for their purported therapeutic properties. It has been estimated that 3% of the world's flowering plants contain pyrrolizidine alkaloids. Honey can contain pyrrolizidine alkaloids, as can grains, milk, offal and eggs. To date (2011), there is no international regulation of PAs in food, unlike those for herbs and medicines. In the earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hepatotoxicity
Hepatotoxicity (from ''hepatic toxicity'') implies chemical-driven liver damage. Drug-induced liver injury (DILI) is a cause of acute and chronic liver disease caused specifically by medications and the most common reason for a drug to be withdrawn from the market after approval. The liver plays a central role in transforming and clearing chemicals and is susceptible to the toxicity from these agents. Certain medicinal agents, when taken in overdoses (e.g. acetaminophen, paracetamol) and sometimes even when introduced within therapeutic ranges (e.g. halothane), may injure the organ. Other chemical agents, such as those used in laboratories and industries, natural chemicals (e.g., alpha-amanitin), and herbal remedies (two prominent examples being kava, though the causal mechanism is unknown, and comfrey, through pyrrolizidine alkaloid content) can also induce hepatotoxicity. Chemicals that cause liver injury are called hepatotoxins. More than 900 drugs have been implicated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Style (flower)
In botany, the style of an angiosperm flower is an organ of variable length that connects the ovary to the stigma. The style does not contain ovules; these are limited to the region of the gynoecium (female organs of the flower) called the "ovary". Structure The style is a narrow extension of the ovary, usually pointing upwards, connecting the ovary to the stigmatic papillae. It may be absent in some plants; in this case, it is referred to as a sessile stigma. Styles generally resemble more or less long tubes. The style can be open (with few cells occupying the central part, or even none), featuring a central canal that may be filled with mucilage. Alternatively, the style can be closed (completely filled with cells). Most plants with syncarpous pistils ( monocotyledons and some eudicotys) have open styles, whereas many eudicots and grasses have closed (solid) styles containing specialized secretory tissues, which connect the stigma to the center of the ovary. These tissue ... [...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 ...

Actinomorphic
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 three 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 Z ...
