Botany is the branch of biology that deals with plants. It involves the study of the structure, properties, and biochemical processes of all forms of plant life, including trees. As a branch of biology, it is also sometimes referred to as plant science(s) or plant biology. Botany covers a wide range of scientific disciplines that study the growth, reproduction, metabolism, development, diseases, and evolution of plants.
Also included within its scope are plant classification and the study of plant diseases and of the interactions of plants with their physical environment. Over the years various specialized branches of botany have developed, and the principles and findings of botany, moreover, have provided the base on which depend such applied plant sciences as agriculture, horticulture, and forestry.
Botany originated as Herbalism, the study and use of plants for their medicinal properties. The early recorded history of botany includes many ancient writings and plant classifications. Examples of early botanical works have been found in ancient sacred texts from India dating back to before 1100 BC, archaic Avestan writings, and works from China before it was unified in 221 BC.
Bach Flower Remedies
Bach flower remedies are dilutions of flower "essences" developed by Dr. Edward Bach. They are similar to homeopathy in many respects and form a part of alternative medicine. Some researchers believe that they exert their claimed effects via the placebo effect, however practitioners feel the "energetic signature" of the flower can be transmitted to the user and affect a person's psychological state.
Remontant is a botanical word that refers to a plant that blooms or produces more than once in a growing season or year. From the French, it literally means 'rising again' and is particularly used to describe cultivated roses that have the ability to flower multiple times a year, which are sometimes called remontants, recurrents or repeat flowering roses.
One of the reasons people get so excited about seeing cherry trees in full blossom this time of the year is that cherry trees are not remontant, which means you only get one chance per year to see them in their glory.
Modern botany traces its roots back to Ancient Greece, specifically to Theophrastus (c. 371-287 BC), a student of Aristotle who invented and described many of its principles and is widely regarded in the scientific community as the "Father of Botany". His major works, 'Enquiry into Plants and On the Causes of Plants,' constitute the most important contributions to botanical science until the Middle Ages, almost seventeen centuries after they were written.
In mid-16th century, "botanical gardens" were founded in a number of Italian universities - the Padua botanical garden in 1545 is usually considered to be the first which is still in its original location. These gardens continued the practical value of earlier "physic gardens", often associated with monasteries, in which plants were cultivated for medical use. They supported the growth of botany as an academic subject. Lectures were given about the plants grown in the gardens and their medical uses demonstrated. Botanical gardens came much later to northern Europe; the first in England was the University of Oxford Botanic Garden in 1621. Throughout this period, botany remained firmly subordinate to medicine.
German physician Leonhart Fuchs (1501Š1566) was one of "the three German fathers of botany", along with theologian Otto Brunfels (1489-1534) and physician Hieronymus Bock (1498-1554) (also called Hieronymus Tragus). Fuchs and Brunfels broke away from the tradition of copying earlier works to make original observations of their own. Bock created his own system of plant classification.
Physician Valerius Cordus (1515Š1544) authored a botanically and pharmacologically important herbal Historia Plantarum in 1544 and a pharmacopoeia of lasting importance, the Dispensatorium in 1546. Naturalist Conrad von Gesner (1516-1565) and herbalist John Gerard (1545-c. 1611) published herbals covering the medicinal uses of plants. Naturalist Ulisse Aldrovandi (1522-1605) was considered the father of natural history, which included the study of plants. In 1665, using an early microscope, Polymath Robert Hooke discovered cells, a term he coined, in cork, and a short time later in living plant tissue.
In the 17th century, as a result of the earlier revival of learning and of increased facilities for travel and study in Europe and Asia, many more plants became known, and some botanists turned from medical botany to attempts to name and catalog all known kinds of plants.
In the 18th century the greatest figure in botany was the Swedish scientist Carolus Linnaeus. His most valuable and lasting contributions were his careful descriptions of approximately 6,000 species arranged in genera (the same arrangement used today), his collation of the species that he knew with the names and descriptions of previous botanists, and his rules of nomenclature.
He established binomial nomenclature - i.e., the naming of each species by two words, of which the first is the name of the genus to which it belongs and the second is a qualifying word, usually an adjective (e.g., the dog rose is Rosa canina).
Even in this early period, botany was becoming specialized. While many botanists were occupied only with the classes and names of plants, the foundations of anatomy, morphology, and physiology were being laid. The important field of genetics was initiated in the 19th century, principally through the work of the Austrian botanist Gregor Mendel.
Modern botany is a broad, multidisciplinary subject with inputs from most other areas of science and technology. Research topics include the study of plant structure, growth and differentiation, reproduction, biochemistry and primary metabolism, chemical products, development, diseases, evolutionary relationships, systematics, and plant taxonomy. Dominant themes in 21st century plant science are molecular genetics and epigenetics, which are the mechanisms and control of gene expression during differentiation of plant cells and tissues. Botanical research has diverse applications in providing staple foods and textiles, in modern horticulture, agriculture and forestry, plant propagation, breeding and genetic modification, in the synthesis of chemicals and raw materials for construction and energy production, in environmental management, and the maintenance of biodiversity.

Can Plants Die Of Old Age? How Long Can They Live? IFL Science - July 12, 2023
As you may have found out if youÕve ever dabbled in horticulture: plants die. Too much water, too little water, insufficient light, lack of nutrients, parasites, disease - these are among the reasons your favorite fern may have made its way to the big plant pot in the sky. Environmental factors, such as these, all help determine a plantÕs longevity, but, as in our own species, genetics also has a part to play. In the absence of adverse conditions, plants may live for longer but they will eventually die of old age.
407-Million-Year-Old Fossilized Plant Bamboozles Scientists By Not Following Fibonacci Sequence IFL Science - July 6, 2023
The world of botany is usually pretty good at following certain rules. It was previously thought that because the Fibonacci sequence is present in the structure of so many extant plant species, it must have evolved in some of the earliest living plant species. However, an ancient species, one of the first examples of a plant with leaves in the fossil record, has thrown a spanner into the understanding of this by having leaves arranged in such a way that canÕt be described by Fibonaaci numbers.

Ethereal New Plant Species Doesn't Use Photosynthesis - It's Found Something Sneakier Science Alert - January 2, 2023
Found widely across East and Southeast Asia, from the Himalayas to Japan, Monotropastrum humile was thought to be a single species. Now researchers from Japan and Taiwan have discovered a pink-hued plant that qualifies as a unique species in its own right, one they've named Monotropastrum kirishimense.
Wood wide webs Š incredible networks of fungi and plant roots that span entire forests Š act as highways for nutrient deliveries as well as wires for transferring information between plants via electrical and chemical signals. These connections help strengthen a forest as a whole by distributing resources from nutrient-rich to nutrient-poor areas of the network. They also allow plants to warn each other of predators and even help protect them from drought.

The largest known plant on Earth - a seagrass roughly three times the size of Manhattan - has been discovered off the coast of Australia BBC - June 1, 2022
Using genetic testing, scientists have determined a large underwater meadow in Western Australia is in fact one plant. It is believed to have spread from a single seed over at least 4,500 years. The seagrass covers about 200 sq km (77 sq miles), researchers from the University of Western Australia said. The team stumbled upon the discovery by accident at Shark Bay, about 800km (497 miles) north of Perth.
164 million-year-old plant fossil is the oldest example of a flowering bud. The discovery changes what we know about the evolution of flowering plants Live Science - January 19, 2022
Researchers have uncovered the earliest example of a flower bud in a 164 million-year-old plant fossil in China. The discovery firmly pushes back the emergence of flowering plants into the Jurassic period, between 145 million and 201 million years ago. The fossil, which was uncovered in the Inner Mongolia region of China, is 1.7 inches (4.2 centimeters) long and 0.8 inches (2 cm) wide. It contains a stem, a leafy branch, a bulbous fruit and a tiny flower bud around 3 square millimeters in size. The researchers have named the new species Florigerminis jurassica.
New Evidence Challenges The Idea That Mutations Are Entirely Random Science Alert - January 13, 2022
It's a common misconception that evolution has a sense of direction Š a notion that biology nerds around the world are constantly trying to correct. But new research reveals there may be a semblance of truth to this misconception, at least more than we ever realized. While it's not as straightforward as mutation with a purpose, it now appears that not all DNA is equal when it comes to being mutable.
How 'Flower Power' Quite Literally Transformed Earth Millions of Years Ago Creating the world for us to flourish Science Alert - January 8, 2022
Following the time of the dinosaurs, it might well be that the evolution of flowering plants drove the explosion in the diversity of life on Earth, according to a 2021 paper. Most of the plants we now eat, drink, wear, and build with are of the flowering variety. They're called angiosperms, which roughly translates from Greek as 'seed vessels'.

Earliest records of three plant groups uncovered in the Permian of Jordan PhysOrg - January 2, 2019
A "hidden cradle of plant evolution" has been uncovered in Jordan. In Permian sedimentary rocks exposed along the east coast of the Dead Sea, a team led by paleobotanists from the University of Mnster discovered well-preserved fossils of plant groups bearing characteristics typical of younger periods of Earth history. The Permian began some 300 million years ago and ended around 250 million years ago.
Researchers unlock secrets of plant development PhysOrg - August 23, 2018
Researchers have discovered an internal messaging system that plants use to manage the growth and division of their cells. These growth-management processes are critical for all organisms, because without them, cells can proliferate out of control as they do in cancers and bacterial infections. Plants use this messaging system to survive under harsh conditions or to compete successfully when conditions are favorable. It tells them when to grow, when to stagnate, when to flower, and when to store resources all based on the prevailing conditions. Understanding how it all works could enable innovations in agriculture, forestry and conservation as climate change takes hold.
Stomata - the plant pores that give us life -arise thanks to a gene called MUTE, scientists report PhysOrg - May 7, 2018
Through photosynthesis, they use sunlight and carbon dioxide to make food, belching out the oxygen that we breathe as a byproduct. This evolutionary innovation is so central to plant identity that nearly all land plants use the same pores - called stomata -to take in carbon dioxide and release oxygen. Stomata are tiny, microscopic and critical for photosynthesis. Thousands of them dot on the surface of the plants. Understanding how stomata form is critical basic information toward understanding how plants grow and produce the biomass upon which we thrive.
Plants colonized the Earth 100 million years earlier than previously thought PhysOrg - February 20, 2018
For the first four billion years of Earth's history, our planet's continents would have been devoid of all life except microbes. All of this changed with the origin of land plants from their pond scum relatives, greening the continents and creating habitats that animals would later invade. The timing of this episode has previously relied on the oldest fossil plants which are about 420 million years old.
