Carl Linnaeus The Younger
Carl Linnaeus the Younger, Carolus Linnaeus the Younger, Carl von Linné den yngre (Swedish; abbreviated Carl von Linné d. y.), or ''Linnaeus filius'' ( Latin for ''Linnaeus the son''; abbreviated L.fil. (outdated) or L.f. (modern) as a botanical authority; 20 January 1741 – 1 November 1783) was a Swedish naturalist. His names distinguish him from his father, the pioneering taxonomist Carl Linnaeus (1707–1778). Biography Carl Linnaeus the Younger was enrolled at the University of Uppsala at the age of nine and was taught science by his father's students, including Pehr Löfling, Daniel Solander, and Johan Peter Falk. In 1763, aged just 22, he succeeded his father as the head of Practical Medicine at Uppsala. His promotion to professor — without taking exams or defending a thesis — caused resentment among his colleagues. His work was modest in comparison to that of his father. His best-known work is the ''Supplementum Plantarum systematis vegetabilium'' of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Volunteer (botany)
In gardening and agronomic terminology, a volunteer is a plant that grows on its own, rather than being deliberately planted by a farmer or gardener. Volunteers often grow from seeds that float in on the wind, are dropped by birds, or are inadvertently mixed into compost. Some volunteers may be encouraged by gardeners once they appear, being watered, fertilized, or otherwise cared for, unlike weeds, which are unwanted volunteers. The action of such plants – to sprout or grow in this fashion – may also be described as volunteering. Volunteers that grow from the seeds of specific cultivars are not reliably identical or similar to their parent and often differ significantly from it. Such open pollinated plants, if they show desirable characteristics, may be selected to become new cultivars. Law This definition also has the meaning in the law context, defining the drug-producing plant like cannabis as a "volunteer" if it grows of its own accord from seeds or roots and is not inte ...

Deadheading (flowers)
Deadheading is the horticultural practice of removing spent flowers from ornamental plants. Deadheading is a widespread form of pruning, since fading flowers are not as appealing and direct a lot of energy into seed development if pollinated. The goal of deadheading is thus to preserve the attractiveness of the plants in beds, borders, containers and hanging baskets, as well as to encourage further blooming. Deadheading flowers with many petals, such as roses, peonies, and camellias prevents them from littering. Deadheading can be done with finger and thumb or with pruning shears, knife, or scissors. Ornamental plants that do not require deadheading are those that do not produce a lot of seed or tend to deadhead themselves. These include lobelias, salvias, and fuchsias. Deadheading is undesirable if the plant's seed is enjoyed by birds, as is the case with many species from the family Asteraceae The family Asteraceae, alternatively Compositae, consists of over 32,000 known ...

Hardiness Zone
A hardiness zone is a geographic area defined as having a certain average annual minimum temperature, a factor relevant to the survival of many plants. In some systems other statistics are included in the calculations. The original and most widely used system, developed by the United States Department of Agriculture (USDA) as a rough guide for landscaping and gardening, defines 13 zones by long-term average annual extreme minimum temperatures. It has been adapted by and to other countries (such as Canada) in various forms. Unless otherwise specified, in American contexts "hardiness zone" or simply "zone" usually refers to the USDA scale. For example, a plant may be described as "hardy to zone 10": this means that the plant can withstand a minimum temperature of 30 °F (−1.1 °C) to 40 °F (4.4 °C). Other hardiness rating schemes have been developed as well, such as the UK Royal Horticultural Society and US Sunset Western Garden Book systems. A heat zone (s ...

Levada Das 25 Fontes
The Levada das 25 Fontes is a levada that is located in Rabaçal, Paul da Serra, Madeira, Portugal. It is one of the most visited levadas on the island. Access is possible via the road ER110 in Paul da Serra. From there walking or taking a bus is possible to the start of the levada which is at the casa do Rabaçal, from here it is possible to get to the lagoon of the Wind (Lagoa do Vento), 25 Fontes Falls and the Risco levada, which leads to the impressive Risco waterfall that emerges from the lagoon. A valley of vertical walls where different types of volcanic rock allow water from the upper water table to emerge in the form of numerous fountains along the walls of the mountain. The only problem is the narrowness of the road, in the middle of the Laurel forest Laurel forest, also called laurisilva or laurissilva, is a type of subtropical forest found in areas with high humidity and relatively stable, mild temperatures.

Wind Dispersal
Biological dispersal refers to both the movement of individuals (animals, plants, fungi, bacteria, etc.) from their birth site to their breeding site ('natal dispersal'), as well as the movement from one breeding site to another ('breeding dispersal'). Dispersal is also used to describe the movement of propagules such as seeds and spores. Technically, dispersal is defined as any movement that has the potential to lead to gene flow. The act of dispersal involves three phases: departure, transfer, settlement and there are different fitness costs and benefits associated with each of these phases. Through simply moving from one habitat patch to another, the dispersal of an individual has consequences not only for individual fitness, but also for population dynamics, population genetics, and species distribution. Understanding dispersal and the consequences both for evolutionary strategies at a species level, and for processes at an ecosystem level, requires understanding on the t ...

Dandelions
''Taraxacum'' () is a large genus of flowering plants in the family Asteraceae, which consists of species commonly known as dandelions. The scientific and hobby study of the genus is known as taraxacology. The genus is native to Eurasia and North America, but the two most commonplace species worldwide, '' T. officinale'' (the common dandelion) and '' T. erythrospermum'' (the red-seeded dandelion), were introduced from Europe into North America, where they now propagate as wildflowers. Both species are edible in their entirety. The common name ''dandelion'' ( , from French , meaning 'lion's tooth') is also given to specific members of the genus. Like other members of the family Asteraceae, they have very small flowers collected together into a composite flower head. Each single flower in a head is called a ''floret''. In part due to their abundance, along with being a generalist species, dandelions are one of the most vital early spring nectar sources for a wide host ...

Rosette (botany)
In botany, a rosette is a circular arrangement of leaves or of structures resembling leaves. In flowering plants, rosettes usually sit near the soil. Their structure is an example of a modified stem in which the internode gaps between the leaves do not expand, so that all the leaves remain clustered tightly together and at a similar height. Some insects induce the development of galls that are leafy rosettes. In bryophytes and algae, a rosette results from the repeated branching of the thallus as the plant grows, resulting in a circular outline. Taxonomies Many plant families have varieties with rosette morphology; they are particularly common in Asteraceae (such as dandelions), Brassicaceae (such as cabbage), and Bromeliaceae. The fern '' Blechnum fluviatile'' or New Zealand Water Fern (''kiwikiwi'') is a rosette plant. Function in flowering plants Often, rosettes form in perennial plants whose upper foliage dies back with the remaining vegetation protecting the plant. ...
