Sisyrinchium Californicum 7
''Sisyrinchium'' is a large genus of annual plant, annual to perennial plant, perennial flowering plant, flowering plants in the family Iridaceae. Native to the New World, the species are known as blue-eyed grasses. Although they are not true grasses (Poaceae), they are monocots. Several species in the eastern United States are threatened or endangered. This may be due to niche species emerging from their unique tendency toward rapid speciation which helps them adapt to specialized arenic (sandy) habitats. Description These are not true grasses, but many species have the general appearance of grasses, as they are low-growing plants with long, thin leaves. They often grow on grasslands. Many species resemble Iris (plant), irises, to which they are more closely related. Most species grow as perennial plants, from a rhizome, though some are short-lived (e.g. ''Sisyrinchium striatum)'', and some are Annual plant, annuals (e.g. ''Sisyrinchium micranthum, Sisyrinchium iridifolium ...

Moraea
''Moraea'', the Cape tulips, is a genus of plants in the family Iridaceae, first described as a genus in 1758. The group is widespread across Africa, the Mediterranean The Mediterranean Sea ( ) is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean basin and almost completely enclosed by land: on the east by the Levant in West Asia, on the north by Anatolia in West Asia and Southern ..., and central and southwestern Asia. The genus name is a tribute to the English botanist Robert More. Description Moraeas have iris-like flowers. The corms of some species have been used as food, however they are usually small and some species have an unpleasant taste, and some are poisonous.

Grassland
A grassland is an area where the vegetation is dominance (ecology), dominated by grasses (Poaceae). However, sedge (Cyperaceae) and rush (Juncaceae) can also be found along with variable proportions of legumes such as clover, and other Herbaceous plant, herbs. Grasslands occur naturally on all continents except Antarctica and are found in most ecoregions of the Earth. Furthermore, grasslands are one of the largest biomes on Earth and dominate the landscape worldwide. There are different types of grasslands: natural grasslands, semi-natural grasslands, and agricultural grasslands. They cover 31–69% of the Earth's land area. Definitions Included among the variety of definitions for grasslands are: * "...any plant community, including harvested forages, in which grasses and/or legumes make up the dominant vegetation." * "...terrestrial ecosystems dominated by herbaceous and shrub vegetation, and maintained by fire, grazing, drought and/or freezing temperatures."

Ancient Greek
Ancient Greek (, ; ) includes the forms of the Greek language used in ancient Greece and the classical antiquity, ancient world from around 1500 BC to 300 BC. It is often roughly divided into the following periods: Mycenaean Greek (), Greek Dark Ages, Dark Ages (), the Archaic Greece, Archaic or Homeric Greek, Homeric period (), and the Classical Greece, Classical period (). Ancient Greek was the language of Homer and of fifth-century Athens, fifth-century Athenian historians, playwrights, and Ancient Greek philosophy, philosophers. It has contributed many words to English vocabulary and has been a standard subject of study in educational institutions of the Western world since the Renaissance. This article primarily contains information about the Homeric Greek, Epic and Classical periods of the language, which are the best-attested periods and considered most typical of Ancient Greek. From the Hellenistic period (), Ancient Greek was followed by Koine Greek, which is regar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elaiophore
An elaiophore (from Gr. ''elaion'' -oil and ''phorein'' -carry) is a plant organ that secretes oil. A distinction is made in: * epithelial elaiophors: oil glands * trichome eaiophores: glandular hairs. The oils consist of fatty acids and/or glycerides, but may also contain other components such as aldehydes, amino acids, carbohydrates, carotenoids, hydrocarbons, ketones, phenolic compounds, saponins and terpenes. Elaiophores occur in the flowers of some families, such as Malpighiaceae, Scrophulariaceae, Iridaceae, Cucurbitaceae, Primulaceae and Solanaceae. Elaiophores can be present on the axial part of the sepals or corollas, on the surface of the lip, at the base of stamens (as in '' Lysimachia vulgaris'') and also on the callus. The oils secreted by the elaiophores act as attractants for pollinating insects. Representatives of several bee families collect these oils to add to the food of the larvae or to line the nest, including the families and subfamilies Melittidae, Ct ...

Cladistics
Cladistics ( ; from Ancient Greek 'branch') is an approach to Taxonomy (biology), biological classification in which organisms are categorized in groups ("clades") based on hypotheses of most recent common ancestry. The evidence for hypothesized relationships is typically shared derived (phylogenetics), derived characteristics (synapomorphies) that are not present in more distant groups and ancestors. However, from an empirical perspective, common ancestors are inferences based on a cladistic hypothesis of relationships of taxa whose Phenotypic trait, character states can be observed. Theoretically, a last common ancestor and all its descendants constitute a (minimal) clade. Importantly, all descendants stay in their overarching ancestral clade. For example, if the terms ''worms'' or ''fishes'' were used within a ''strict'' cladistic framework, these terms would include humans. Many of these terms are normally used Paraphyly, paraphyletically, outside of cladistics, e.g. as a 'E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

''Sisyrinchium bellum'', the western blue-eyed grass or Californian blue-eyed grass, is the common blue-eyed grass of California and Oregon in and west of the Sierra Nevada, its range extending south into Baja California. In parts of its range, western blue-eyed grass has previously been classified as ''Sisyrinchium eastwoodiae'', ''S. greenei'' and ''S. hesperium'', but these names are now considered synonyms.

Annual Plant
An annual plant is a plant that completes its life cycle, from germination to the production of seeds, within one growing season, and then dies. Globally, 6% of all plant species and 15% of herbaceous plants (excluding trees and shrubs) are annuals. The annual life cycle has independently emerged in over 120 different plant families throughout the entire angiosperm phylogeny. The evolutionary and ecological drivers of the annual life cycle Traditionally, there has been a prevailing assumption that annuals have evolved from perennial ancestors. However, recent research challenges this notion, revealing instances where perennials have evolved from annual ancestors. Intriguingly, models propose that transition rates from an annual to a perennial life cycle are twice as fast as the reverse transition. The life-history theory posits that annual plants are favored when adult mortality is higher than seedling (or seed) mortality, i.e., annuals will dominate environments with dis ...
