Munzothamnus
''Munzothamnus'' is a monotypic genus of flowering plants in the family Asteraceae containing the single species ''Munzothamnus blairii'', which is known by the common name Blair's wirelettuce, or Blair's munzothamnus. It is Endemism, endemic to San Clemente Island, one of the Channel Islands of California. It grows along steep, rocky cliffsides and canyons on the island. It is a shrub producing a fleshy, woolly stem usually over a meter in height, often approaching two meters. Leaves occur in tufts at the ends of the stem branches. They are up to 15 centimeters long, oblong in shape, and sometimes very shallowly lobed. They are woolly when new but lose their hairs and become shiny green with age. The inflorescence is a large array of up to 35 Head (botany), flower heads. Each head has a cylindrical base under a centimetre long and contains 9 to 12 light lavender or pinkish flowers. Each flower is a ray floret with an erect tube and a strap-shaped ligule with a toothed tip. The lig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cichorieae
The Cichorieae (also called Lactuceae) are a tribe in the plant family Asteraceae that includes 93 genera, more than 1,600 sexually reproductive species and more than 7,000 Apomixis, apomictic species. They are found primarily in temperate regions of the Eastern Hemisphere. Cichorieae all have milky latex and flowerheads that only contain one type of Glossary of botanical terms#floret, floret. The genera ''Gundelia'' and ''Warionia'' only have Asteraceae#Floral heads, disk florets, while all other genera only have Asteraceae#Floral heads, ligulate florets.

Philip Munz
Philip Alexander Munz (1892–1974) was an American botanist, plant taxonomist and educator who worked at the Rancho Santa Ana Botanic Garden and was a professor of botany at Pomona College, serving as dean there for three years. In 1935 Munz published his ''Manual of Southern California Botany''. Munz compiled the voluminous ''A California Flora'' with David D. Keck, published by the University of California Press in 1959, and with a supplement published in 1968. Munz published ''A California Flora'' without any research support and with a relatively small subvention for publication from the University of California Press. In 1974, his book ''A Flora of Southern California'' was published posthumously, with the Family (taxonomy), botanical families presented in an alphabetical order. List of selected publications Munz authored four popular plant guides for general readers interested in botany but untrained in plant taxonomy, published by the University of California Press, and ref ...

San Clemente Island
San Clemente Island (Tongva: ''Kinkipar''; Spanish: ''Isla de San Clemente'') is the southernmost of the Channel Islands of California. It is owned and operated by the United States Navy, and is a part of Los Angeles County. It is administered by Naval Base Coronado. It is long and has of land. The 2018 census estimates 148 military and civilian personnel reside on the island. The city of San Clemente in Orange County, California is named after the island. Geography Topography Geologically, the island is described as being "the upper part of a tilted and gently arched northwestward-trending block of the earth's crust that has a straight, steep northeastern slope and a more irregular and much gentler southwestern slope" that is composed primarily of volcanic rock, with the northeast boundary of the island having a large fault that parallels most of the major faults on the California mainland. San Clemente Island has some of the best examples of marine terraces, and has trench-li ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ivan Murray Johnston
I. M. (Ivan Murray) Johnston (February 28, 1898–May 31, 1960), was a United States Botany, botanist. He studied at Pomona College in Claremont, California and at Harvard University. His plant collections are housed in the ''Rancho Santa Ana Botanic Garden'', in Claremont, and also in the ''Gray Herbarium'' of Harvard University. His areas of interest, were, among others: Fern, Pteridophytes, Spermatophytes Honours In 1925, German botanist August Brand, named a genus of flowering plants (belonging to the family Boraginaceae), from South America and southern states in USA, as ''Johnstonella'' in his honour. Then in 1933, botanist O.E.Schulz named a genus of flowering plants (belonging to the family Brassicaceae), from Chile as ''Ivania (plant), Ivania''. In 1936, botanist Hsen Hsu Hu published ''Sinojohnstonia'', which is a genus of flowering plants from China, belonging to the family Boraginaceae. Lastly in 1975, another botanist Kazmi, named a monotypic genus of flowering plan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Asteraceae
The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales. Commonly referred to as the aster, daisy, composite, or sunflower family, Compositae were first described in the year 1740. The number of species in Asteraceae is rivaled only by the Orchidaceae, and which is the larger family is unclear as the quantity of extant species in each family is unknown. Most species of Asteraceae are annual, biennial, or perennial herbaceous plants, but there are also shrubs, vines, and trees. The family has a widespread distribution, from subpolar to tropical regions in a wide variety of habitats. Most occur in hot desert and cold or hot semi-desert climates, and they are found on every continent but Antarctica. The primary common characteristic is the existence of sometimes hundreds of tiny individual florets which are held together by protective involucres in flower heads, or more technicall ...

Endemism
Endemism is the state of a species being found in a single defined geographic location, such as an island, state, nation, country or other defined zone; organisms that are indigenous to a place are not endemic to it if they are also found elsewhere. For example, the Cape sugarbird is found exclusively in southwestern South Africa and is therefore said to be ''endemic'' to that particular part of the world. An endemic species can be also be referred to as an ''endemism'' or in scientific literature as an ''endemite''. For example '' Cytisus aeolicus'' is an endemite of the Italian flora. '' Adzharia renschi'' was once believed to be an endemite of the Caucasus, but it was later discovered to be a non-indigenous species from South America belonging to a different genus. The extreme opposite of an endemic species is one with a cosmopolitan distribution, having a global or widespread range. A rare alternative term for a species that is endemic is "precinctive", which applies to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Channel Islands Of California
The Channel Islands () are an eight-island archipelago located within the Southern California Bight in the Pacific Ocean, off the coast of California. The four Northern Channel Islands are part of the Transverse Ranges geologic province, and the four Southern Channel Islands are part of the Peninsular Ranges province. Five of the islands are within the Channel Islands National Park, and the waters surrounding these islands make up Channel Islands National Marine Sanctuary. The Nature Conservancy was instrumental in establishing the Channel Islands National Marine Sanctuary. The islands were inhabited as early as 13,000 years ago, the earliest paleontological evidence of humans in North America. They are the easternmost islands in the Pacific Island group. The Chumash and Tongva Native Americans who lived later on the islands may be the descendants of the original inhabitants, but they were then displaced by Spaniards who used the islands for fishing and agriculture.

Shrub
A shrub (often also called a bush) is a small-to-medium-sized perennial woody plant. Unlike herbaceous plants, shrubs have persistent woody stems above the ground. Shrubs can be either deciduous or evergreen. They are distinguished from trees by their multiple stems and shorter height, less than tall. Small shrubs, less than 2 m (6.6 ft) tall are sometimes termed as subshrubs. Many botanical groups have species that are shrubs, and others that are trees and herbaceous plants instead. Some definitions state that a shrub is less than and a tree is over 6 m. Others use as the cut-off point for classification. Many species of tree may not reach this mature height because of hostile less than ideal growing conditions, and resemble a shrub-sized plant. However, such species have the potential to grow taller under the ideal growing conditions for that plant. In terms of longevity, most shrubs fit in a class between perennials and trees; some may only last about five y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Inflorescence
An inflorescence is a group or cluster of flowers arranged on a stem that is composed of a main branch or a complicated arrangement of branches. Morphologically, it is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis, as well as variations in the proportions, compressions, swellings, adnations, connations and reduction of main and secondary axes. One can also define an inflorescence as the reproductive portion of a plant that bears a cluster of flowers in a specific pattern. The stem holding the whole inflorescence is called a peduncle. The major axis (incorrectly referred to as the main stem) above the peduncle bearing the flowers or secondary branches is called the rachis. The stalk of each flower in the inflorescence is called a pedicel. A flower that is not part of an inflorescence is called a solitary flower and its stalk is al ...

Head (botany)
A pseudanthium (Greek for "false flower"; ) is an inflorescence that resembles a flower. The word is sometimes used for other structures that are neither a true flower nor a true inflorescence. Examples of pseudanthia include flower heads, composite flowers, or capitula, which are special types of inflorescences in which anything from a small cluster to hundreds or sometimes thousands of flowers are grouped together to form a single flower-like structure. Pseudanthia take various forms. The real flowers (the florets) are generally small and often greatly reduced, but the pseudanthium itself can sometimes be quite large (as in the heads of some varieties of sunflower). Pseudanthia are characteristic of the daisy and sunflower family (Asteraceae), whose flowers are differentiated into ray flowers and disk flowers, unique to this family. The disk flowers in the center of the pseudanthium are actinomorphic and the corolla is fused into a tube. Flowers on the periphery are zygomorp ...

Achene
An achene (; ), also sometimes called akene and occasionally achenium or achenocarp, is a type of simple dry fruit produced by many species of flowering plants. Achenes are monocarpellate (formed from one carpel) and indehiscent (they do not open at maturity). Achenes contain a single seed that nearly fills the pericarp, but does not adhere to it. In many species, what is called the "seed" is an achene, a fruit containing the seed. The seed-like appearance is owed to the hardening of the fruit wall (pericarp), which encloses the solitary seed so closely as to seem like a seed coat. Examples The fruits of buttercup, buckwheat, caraway, quinoa, amaranth, and cannabis are typical achenes. The achenes of the strawberry are sometimes mistaken for seeds. The strawberry is an accessory fruit with an aggregate of achenes on its outer surface, and what is eaten is accessory tissue. A rose produces an aggregate of achene fruits that are encompassed within an expanded hypanthium (aka f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
