Erigeron Socorrensis
''Erigeron socorrensis'' is a Mexican species of flowering plant in the family Asteraceae known by the common name Socorro Island fleabane. It has been found only on Socorro Island in Mexico, part of the State of Colima. This is a small, volcanic island about south-southwest of the southern end of the Peninsula of Baja California, the largest of the Revillagigedo Islands. ''Erigeron socorrensis'' is a shrub up to tall, with a large woody caudex. It has narrowly oblanceolate leaves up to long. One plant can produce several groups of small flower heads, each group at the end of a long, thin stalk. Each head is long, with several white ray florets surrounding several yellow disc floret The family Asteraceae, alternatively Compositae, consists of over 32,000 known species of flowering plants in over 1,900 genera within the order Asterales.

Townshend Stith Brandegee
Townshend Stith Brandegee (February 16, 1843 – April 7, 1925) was an American botanist. He was an authority on the flora of Baja California and the Channel Islands of California, Channel Islands of California. Early life Brandegee was born on February 16, 1843, in Berlin, Connecticut. From 1862 to 1864 he served in the Connecticut Artillery and later decided to become an engineer. He got his degree in engineering from Sheffield Scientific School but then pursued botany after he participated at some classes with Daniel Cady Eaton in Yale University. When he graduated from there, he became a county surveyor and city engineer at Canon City, Colorado where in free time he also collected certain species of plants. He was accustomed with John H. Redfield and Asa Gray the later of which suggested him to join Ferdinand V. Hayden's expedition to southwest Colorado and Utah where he will use his surveyor skills as well as botanical. He was hired as a railroad surveyor in both Arkansas and ... [...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 ...

Socorro Island
Socorro Island ( es, Isla Socorro) is a small volcanic island in the Revillagigedo Islands, a Mexican possession lying off the country's western coast. The size is 16.5 by 11.5 km (10.25 by 7.15 miles), with an area of . It is the largest of the four islands of the Revillagigedo Archipelago. The last eruption was in 1993. Geology The island rises abruptly from the sea to in elevation at its summit. Socorro Island is the emerged summit of a massive, predominately submarine shield volcano. The island is part of the northern Mathematicians Ridge, a mid-ocean ridge that became largely inactive 3.5 million years ago when activity moved to the East Pacific Rise. All four islands along with the many seamounts on the ridge are post-abandonment alkaline volcanoes. Socorro Island is unusual in that it is the only dominantly silicic peralkaline volcanic island in the Pacific Ocean. It most recently erupted in late Januaryearly February, 1993, which was a submarine flank eruption ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colima
Colima (), officially the Free and Sovereign State of Colima ( es, Estado Libre y Soberano de Colima), is one of the 31 states that make up the Political divisions of Mexico, 32 Federal Entities of Mexico. It shares its name with its capital and main city, Colima City, Colima. Colima is a small state located in Western Mexico on the central Pacific coast, and includes the four oceanic Revillagigedo Islands. Mainland Colima shares borders with the states of Jalisco and Michoacán. In addition to the capital city of Colima, the main cities are Manzanillo, Colima, Manzanillo and Tecomán. Colima is the fourth smallest state in Mexico and has the second smallest population, but has one of Mexico's highest standards of living and the lowest unemployment. However, Colima is also the state with the highest murder rate per capita and one of the highest crime rates, due to its ports being a contested area for cartels. Geography The state covers a territory of 5,455 km2 and is th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Revillagigedo Islands
The Revillagigedo Islands ( es, Islas Revillagigedo, ) or Revillagigedo Archipelago are a group of four volcanic islands in the Pacific Ocean, known for their unique ecosystem. They lie approximately from Socorro Island south and southwest of Cabo San Lucas, the southern tip of the Baja California Peninsula, and west of Manzanillo, Colima, Manzanillo. Historically linked to the Mexican state of Colima, to which they were granted in 1861 to establish a penal colony, the islands are under Mexican federal property and jurisdiction. In July 2016, the Revillagigedo Archipelago was inscribed as a UNESCO World Heritage Site, and in November 2017 they were declared to be a marine reserve and a List of national parks of Mexico, national park of Mexico. Some of the volcanoes are active, with the last eruption of Volcán Bárcena in 1953, and Socorro (volcano), Socorro in 1993. Travelling to the islands from their nearest land point takes approximately 26 to 30 hours, as they are typicall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caudex
A caudex (plural: caudices) of a plant is a stem, but the term is also used to mean a rootstock and particularly a basal stem structure from which new growth arises.pages 456 and 695 In the strict sense of the term, meaning a stem, "caudex" is most often used with plants that have a different stem morphology from the typical angiosperm dicotyledon stem: examples of this include palms, ferns, and cycads. The related term caudiciform, literally meaning stem-like, is sometimes used to mean pachycaul, thick-stemmed. Etymology The term is from the Latin Latin (, or , ) is a classical language belonging to the Italic branch of the Indo-European languages. Latin was originally a dialect spoken in the lower Tiber area (then known as Latium) around present-day Rome, but through the power of the ... ''caudex'', a noun meaning "tree trunk".

Leaf Shape
The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular or irregular, may be smooth or bearing hair, bristles or spines. For more terms describing other aspects of leaves besides their overall morphology see the leaf article. The terms listed here all are supported by technical and professional usage, but they cannot be represented as mandatory or undebatable; readers must use their judgement. Authors often use terms arbitrarily, or coin them to taste, possibly in ignorance of established terms, and it is not always clear whether because of ignorance, or personal preference, or because usages change with time or context, or because of variation between specimens, even specimens from the same plant. For example, whether to call leaves on the same tree "acuminate", "lanceolate", or "linear" could ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flower Heads
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 ...

Erigeron
''Erigeron'' () is a large genus of plants in the family Asteraceae. It is closely related to the genus ''Aster'' and the true daisies in the genus ''Bellis''. The genus has a cosmopolitan distribution in dry, mountainous areas and grassland, with the highest diversity in North America. Etymology Its English name, fleabane, is shared with related plants in several other genera. It appears to be derived from a belief that the dried plants repelled fleas or that the plants were poisonous to fleas. The generic name ''Erigeron'' is derived from the Ancient Greek words (''êri'') "early in the morning" and (''gérōn'') "old man", a reference to the appearance of the white hairs of the fruit soon after flowering or possibly alluding to the early appearance of the seed heads. The noun is masculine, so that specific epithets should have masculine endings (e.g. ''glaucus'') to agree with it. However, authors have incorrectly used neuter endings (e.g. ''glaucum''), because the ending ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
