''Ulmus crassifolia'' Nutt., the Texas cedar elm or simply cedar elm, is a deciduous tree native to south-central North America, mainly in southern and eastern Texas, southern Oklahoma, Arkansas, and Louisiana, with small populations in western Mississippi, southwest Tennessee, and north-central Florida; it also occurs in northeastern Mexico.Todzia, C. A. & Panero, J. L. (2006). A new species of Ulmus (Ulmaceae) from southern Mexico and a synopsis of the species in Mexico. ''Brittonia'', Vol 50, (3): 346 It is the most common elm tree in Texas. The tree typically grows well in flat valley bottom areas referred to as cedar elm flats. The common name cedar elm is derived from the trees' association with juniper trees, locally known as cedars. Description The cedar elm is a medium to large deciduous tree growing to 24–27 m tall with a rounded crown. The leaves are small, 2.5–5 cm long by 1.3–2 cm broad, with an oblique base, and distinguish it from '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Nuttall
Thomas Nuttall (5 January 1786 – 10 September 1859) was an England, English botany, botanist and zoologist who lived and worked in America from 1808 until 1841. Nuttall was born in the village of Long Preston, near Settle, North Yorkshire, Settle in the West Riding of Yorkshire and spent some years as an apprentice printer in England. Soon after going to the United States he met professor Benjamin Smith Barton in Philadelphia. Barton encouraged his strong interest in natural history. Early explorations in the United States In 1810 he travelled to the Great Lakes and in 1811 travelled on the Astor Expedition led by William Price Hunt on behalf of John Jacob Astor up the Missouri River. Nuttall was accompanied by the English botanist John Bradbury (naturalist), John Bradbury, who was collecting plants on behalf of Liverpool botanical gardens.

Monarch Butterflies
The monarch butterfly or simply monarch (''Danaus plexippus'') is a milkweed butterfly (subfamily Danainae) in the family Nymphalidae. Other common names, depending on region, include milkweed, common tiger, wanderer, and black-veined brown. It is amongst the most familiar of North American butterflies and an iconic pollinator, although it is not an especially effective pollinator of milkweeds. Its wings feature an easily recognizable black, orange, and white pattern, with a wingspan of . A Müllerian mimic, the viceroy butterfly, is similar in color and pattern, but is markedly smaller and has an extra black stripe across each hindwing. The eastern North American monarch population is notable for its annual southward late-summer/autumn instinctive migration from the northern and central United States and southern Canada to Florida and Mexico. During the fall migration, monarchs cover thousands of miles, with a corresponding multigenerational return north in spring. The western ...

William Jackson Bean (26 May 1863 in Yorkshire – 19 April 1947 in Kew, Surrey) was a British botanist and plantsman, who was curator of Kew Gardens from 1922 to 1929. He was responsible for some of the present collections of trees and woody plants there. Bean began his career at Kew Gardens as a trainee gardener. He remained at Kew for over 45 years, reaching the position of curator in 1922. Bean wrote a history of Kew Gardens, which was published in 1908. He wrote the first two-volume edition of the reference work ''Trees and Shrubs Hardy in the British Isles'', which was published in 1914. A revised four-volume edition of this work remains a standard reference work for woody plants grown in Britain today. Bean retired from Kew in 1929.

Späth Nursery
The Späth (often spelt ''Spaeth'') family created one of the world's most notable plant nurseries of the 19th and early 20th centuries. The nursery had been founded in 1720 by Christoph Späth but removed to the erstwhile district of Baumschulenweg (lit. 'nursery way'; now part of the Treptow-Köpenick district) in south-east Berlin in 1863 when Franz Ludwig Späth (1839 - 1913) succeeded his father Ludwig as manager when aged only 25. By the end of the 19th century, the nursery was the largest in the world, occupying 120 hectares. In 1874 Franz built a mansion on the site, now part of Humboldt University and, five years later, established an arboretum. After his death in Britz in 1913, Franz Späth was succeeded by his son, Hellmut, who revived the nursery's flagging fortunes during the Depression by joining the Nazi Party and securing lucrative landscaping contracts for the new autobahns and other public works. However, his outspoken criticism of the Nazi regime saw him i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australasia
Australasia is a region that comprises Australia, New Zealand and some neighbouring islands in the Pacific Ocean. The term is used in a number of different contexts, including geopolitically, physiogeographically, philologically, and ecologically, where the term covers several slightly different, but related regions. Derivation and definitions Charles de Brosses coined the term (as French ''Australasie'') in ''Histoire des navigations aux terres australes'' (1756). He derived it from the Latin for "south of Asia" and differentiated the area from Polynesia (to the east) and the southeast Pacific (Magellanica). In the late 19th century, the term Australasia was used in reference to the "Australasian colonies". In this sense it related specifically to the British colonies south of Asia: New South Wales, Queensland, South Australia, Tasmania, Western Australia, Victoria (i.e., the Australian colonies) and New Zealand. Australasia found continued geopolitical attention in the earl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Texas Root Rot
Texas root rot (also known as Phymatotrichopsis root rot, Phymatotrichum root rot, cotton root rot, or, in the older literature, Ozonium root rot) is a disease that is fairly common in Mexico and the southwestern United States resulting in sudden wilt and death of affected plants, usually during the warmer months. It is caused by a soil-borne fungus named ''Phymatotrichopsis omnivora'' that attacks the roots of susceptible plants. It was first discovered in 1888 by Pammel and later named by Duggar in 1916. A monograph of this disease, which includes a historical review, was written by R.B. Streets and H.E. Bloss in 1973. Host and symptoms ''Phymatotrichopsis omnivora'' is a necrotic fungal pathogen that has a very broad host range, attacking almost 2000 dicotyledonous species. It inhabits alkaline, calcareous soils in southwestern United States. It particularly targets dicots as most monocots are immune. Economically important plant hosts affected by the pathogen include: p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phoradendron Tomentosum
''Phoradendron tomentosum'', the leafy mistletoe, hairy mistletoe or Christmas mistletoe, is a plant parasite. It is characterized by its larger leaves and smaller berries than dwarf mistletoe. Leafy mistletoe seldom kill but they do rob their hosts of moisture and some minerals, causing stress during drought and reducing crop productions on fruit and nut trees. Leafy mistletoe has the ability to photosynthesize on its own but it relies on other plants in order to obtain its nutrients. It attaches itself to a tree and then grows haustoria, in order to get the food and water it needs. Host and symptoms Symptoms can include dieback, swelling, formations of witches’ broom and weakened branches. Leafy mistletoe can occur on several hundred host species. These include hardwood trees. Signs are green leafy green stems, and berries. Disease cycle Birds are the primary disease vector in the dispersal of the plant parasite leafy mistletoe. Birds consume the seeds from the fruit of ''P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
