Brickelliastrum Fendleri
''Brickelliastrum fendleri'', known by the common name Fendler's brickellbush, is a species of flowering plant in the family Asteraceae. It is native to New Mexico, Arizona, Texas, and Mexico. Description ''Brickelliastrum fendleri'' is a perennial herb or subshrub. It can reach around 80 centimeters tall. It produces cymose panicles, each with a few heads of flowers. Its bright white flowers help distinguish it from the similar species '' Brickellia grandiflora'', which has more cream or yellow-colored flowers. ''Brickellia grandiflora'' also has a row of bracts around the outer calyx, which ''Brickelliastrum fendleri'' lacks. ''Brickelliastrum fendleri'' has simple leaves that are usually oppositely arranged. Its deltoid or triangular-ovate leaves have crenate-serrate to serrate margins, and truncate to cordate bases. It is fibrous-rooted and has woody caudices. The fruit is a cypsela, although it is often incorrectly referred to as an achene. Fruits are 5-ribbed. Ecology ...

Asa Gray
Asa Gray (November 18, 1810 – January 30, 1888) is considered the most important American botany, botanist of the 19th century. His ''Darwiniana'' (1876) was considered an important explanation of how religion and science were not necessarily mutually exclusive. Gray was adamant that a genetic connection must exist between all members of a species. He was also strongly opposed to the ideas of hybridization within one generation and special creation in the sense of its not allowing for evolution. He was a strong supporter of Darwin, although Gray's theistic evolution was guided by a Creator. As a professor of botany at Harvard University for several decades, Gray regularly visited, and corresponded with, many of the leading natural scientists of the era, including Charles Darwin, who held great regard for him. Gray made several trips to Europe to collaborate with leading European scientists of the era, as well as trips to the southern and western United States. He also built a ...

Caudex
A caudex (: 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 largest of all caudices is that of the ombu (''Phytolacca dioecea'') of the Pampas of South America which can be fifty feet (fifteen meters) thick. The related term caudiciform, literally meaning stem-like, is sometimes used to mean pachycaul, thick-stemmed. Caudices should not be confused with lignotubers which can also be very large. Etymology The term is from the Latin Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally spoken by the Latins (Italic tribe), Latins in Latium (n ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flora Of Northeastern Mexico
Flora (: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring ( indigenous) native plants. The corresponding term for animals is ''fauna'', and for fungi, it is '' funga''. Sometimes bacteria and fungi are also referred to as flora as in the terms ''gut flora'' or ''skin flora'' for purposes of specificity. Etymology The word "flora" comes from the Latin name of Flora, the goddess of plants, flowers, and fertility in Roman mythology. The technical term "flora" is then derived from a metonymy of this goddess at the end of the sixteenth century. It was first used in poetry to denote the natural vegetation of an area, but soon also assumed the meaning of a work cataloguing such vegetation. Moreover, "Flora" was used to refer to the flowers of an artificial garden in the seventeenth century. The distinction between vegetation (the general appearance of a community) and flora (the taxonomic composition of a community) wa ...

Augustus Fendler
Augustus Fendler (January 10, 1813 – November 27, 1883), alternatively written as August Fendler, was a Prussian-born American natural history collector. Fendler gained his first taste of exploration as a physician's assistant. He partook in an inspection trip of the cholera quarantine camps on the Russian border of Prussia. Upon his return, he briefly worked as a tanner, then spent a year in a polytechnical school based in Berlin. He dropped out and found his way to Bremen, eventually sailing to Baltimore, Maryland in 1836. Fendler initially found work as a tanner in Philadelphia, then moved to New York City and pursued lamp manufacturing. The panic of 1837 lead to the closing of his shop, and consequently, he left New York for St. Louis in 1838. He resumed working in the lamp business, but left the city shortly before Christmas the same year. Fendler continued south through New Orleans, before heading west to Texas. He was granted a land permit in Houston, but abandoned the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brickellia
''Brickellia'' is a North American genus of about 100 to 110 species of plants in the family Asteraceae, known commonly as brickellbushes. They are found in Canada, the United States, Mexico, and Central America. Many species are native to the American southwest, especially Texas. ''Brickellia'' is among the more basal (biology), basal lineages of the Eupatorieae and should not be assigned to a subtribe pending further research. They are mostly woody perennial shrubs. Some species have a very strong pleasant scent, while others smell distasteful. All contain high amounts of essential oils. germacrene, Germacrene D, a natural insecticide, is found in ''Brickellia veronicifolia, B. veronicifolia'' and probably other species, if not all. Despite their chemical defenses, brickellbushes are food for caterpillars of certain Lepidoptera. These include the noctuidae, noctuid moths ''Schinia trifascia'', ''Schinia oleagina'', which is known only from ''Brickellia'', ''Schinia buta'', whi ...

Cypsela (botany)
Asteraceae () is a large family of flowering plants that consists of over 32,000 known species in over 1,900 genera within the order Asterales. 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. The Asteraceae were first described in the year 1740 and given the original name Compositae. The family is commonly known as the aster, daisy, composite, or sunflower family. Most species of Asteraceae are herbaceous plants, and may be annual, biennial, or perennial, 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. Their common primary characteristic is compound flower heads, technically known as capitula, consisting of sometimes hundreds of t ...

Robert Merrill King
The name Robert is an ancient Germanic given name, from Proto-Germanic "fame" and "bright" (''Hrōþiberhtaz''). Compare Old Dutch ''Robrecht'' and Old High German ''Hrodebert'' (a compound of '' Hruod'' () "fame, glory, honour, praise, renown, godlike" and ''berht'' "bright, light, shining"). It is the second most frequently used given name of ancient Germanic origin.Reaney & Wilson, 1997. ''Dictionary of English Surnames''. Oxford University Press. It is also in use as a surname. Another commonly used form of the name is Rupert. After becoming widely used in Continental Europe, the name entered England in its Old French form ''Robert'', where an Old English cognate form (''Hrēodbēorht'', ''Hrodberht'', ''Hrēodbēorð'', ''Hrœdbœrð'', ''Hrœdberð'', ''Hrōðberχtŕ'') had existed before the Norman Conquest. The feminine version is Roberta. The Italian, Portuguese, and Spanish form is Roberto. Robert is also a common name in many Germanic languages, including Eng ...

Pseudanthium
A pseudanthium (; : pseudanthia) 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 (biology), 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 (flower), corolla is fused into a tube. Flowers on th ...
