Malacothamnus Densiflorus
''Malacothamnus densiflorus'' is a species of flowering plant in the mallow family, which has two varieties. It is endemic to the Peninsular Ranges of southwestern California and northwestern Baja California. Morse, K. 2023Malacothamnus Volume 3: A Revised Treatment of the Genus Malacothamnus (Malvaceae) Based on Morphological and Phylogenetic Evidence./ref> Varieties Two varieties are recognized in ''Malacothamnus densiflorus'': ''Malacothamnus densiflorus'' var. ''densiflorus'' and ''Malacothamnus densiflorus'' var. ''viscidus''. The geographic ranges of these varieties only overlap slightly. ''Malacothamnus densiflorus'' var. ''densiflorus'' is known by the common names few-rayed bushmallow, many-flowered bushmallow, and dense-flowered bushmallow. It can be mostly distinguished from the rest of the genus by the nonglandular trichomes on the abaxial calyx surface, which are relatively long, relatively sparse (especially on the calyx tube), and simple to relatively few-rayed. ...

Sereno Watson
Sereno Watson (December 1, 1826 in East Windsor Hill, Connecticut – March 9, 1892 in Cambridge, Massachusetts) was an American botanist. Graduating from Yale in 1847 in Biology, he drifted through various occupations until, in California, he joined the Clarence King Expedition and eventually became its expedition botanist. Appointed by Asa Gray as assistant in the Gray Herbarium of Harvard University in 1873, he later became its curator, a position he maintained until his death. Watson was elected a Fellow of the American Academy of Arts and Sciences in 1874, and a member of the National Academy of Sciences in 1889.

Otay Mountain
Otay Mountain is a mountain located in San Diego County, California. It is the highest summit of the San Ysidro Mountains. The mountain is located in the Otay Mountain Wilderness Area. The physical border separating Mexico and the United States (which can be found near Otay Mountain) has received criticism for the harm it allegedly perpetuated to the environment, both in its construction and in its very nature. History The name "Otay" comes from the Kumeyaay word ''otai'', which means "brushy". On March 16, 1991, a Hawker Siddeley HS-125 airplane carrying seven members of singer Reba McEntire's band, plus her business manager and two pilots, crashed into the side of the mountain after taking off from nearby Brown Field Municipal Airport, killing all ten on board. Otay Mountain has had several wildfire incidents in the past. The plant life in Otay Mountain "burned completely" in 2003, and another wildfire happened later in 2007. A border fence spanning the Mexico–Uni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural History Of The Peninsular Ranges
Nature, in the broadest sense, is the physical world or universe. "Nature" can refer to the phenomena of the physical world, and also to life in general. The study of nature is a large, if not the only, part of science. Although humans are part of nature, human activity is often understood as a separate category from other natural phenomena. The word ''nature'' is borrowed from the Old French ''nature'' and is derived from the Latin word ''natura'', or "essential qualities, innate disposition", and in ancient times, literally meant "birth". In ancient philosophy, ''natura'' is mostly used as the Latin translation of the Greek word ''physis'' (φύσις), which originally related to the intrinsic characteristics of plants, animals, and other features of the world to develop of their own accord. The concept of nature as a whole, the physical universe The universe is all of space and time and their contents, including planets, stars, galaxies, and all other forms ...

Flora Of Baja California
Flora is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. Sometimes bacteria and fungi are also referred to as flora, as in the terms '' gut flora'' or '' skin flora''. 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) was first made by Jules Thurmann (1849). Prior to this, the two terms were used indiscriminately.Thurmann, J. (1849). ''Essai de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Malacothamnus
''Malacothamnus'' (bushmallow) is a genus of shrubs found throughout much of mainland California and on three of the Channel Islands. Outside of California, ''Malacothamnus'' is known from the northern half of Baja California and from a few disjunct locations in Arizona. Plants of this genus are most commonly found in early-successional, post-burn plant communities.Kearney, T. H. 1951. “The Genus Malacothamnus, Greene (Malvaceae).” Leaflets of Western Botany VI (6):113–40. ''Malacothamnus'' are currently thought to be most closely related to the ''Iliamna (plant), Iliamnas'' of the US interior and the ''Phymosias'' of Mexico, Central America, and the Caribbean. Taxonomy Taxonomy in the genus Malacothamnus has been controversial due to overlapping morphological variation and differences in opinion about how to treat that variation.Kearney, T. H. 1955. “Notes on Malvaceae VII: A New Variety in Malacothamnus.” Leaflets of Western Botany VII (12):289–90. Bates, D. M. 2015. ...

Edward Lee Greene
Edward Lee Greene (August 20, 1843–November 10, 1915) was an American botanist known for his numerous publications including the two-part ''Landmarks of Botanical History'' and the describing of over 4,400 species of plants in the American West. Early life Edward Lee Greene was born on August 20, 1843 in Hopkinton, Rhode Island. In 1859 Greene moved to Wisconsin and began studying at Albion Academy, a very reputable institution with a religious emphasis. There Greene met Thure Kumlien, a Swedish Naturalist with an interest in botany. Greene accompanied Kumlein on field trips, further developing Greene's interest in botany. In August 1862, Greene joined his father and brothers in joining the 13th Wisconsin Volunteer Infantry Regiment of the Union Army. Though he never rose above the rank of private in his three years of service, Greene was able to advance his botanical studies, collecting specimens as he marched through Tennessee, Kentucky and Alabama.

Trichome
Trichomes (); ) are fine outgrowths or appendages on plants, algae, lichens, and certain protists. They are of diverse structure and function. Examples are hairs, glandular hairs, scales, and papillae. A covering of any kind of hair on a plant is an indumentum, and the surface bearing them is said to be pubescent. Algal trichomes Certain, usually filamentous, algae have the terminal cell produced into an elongate hair-like structure called a trichome. The same term is applied to such structures in some cyanobacteria, such as '' Spirulina'' and ''Oscillatoria''. The trichomes of cyanobacteria may be unsheathed, as in ''Oscillatoria'', or sheathed, as in ''Calothrix''. These structures play an important role in preventing soil erosion, particularly in cold desert climates. The filamentous sheaths form a persistent sticky network that helps maintain soil structure. Plant trichomes Plant trichomes have many different features that vary between both species of plants an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
