It describes how to collect, press, dry, poison, mount, label, and store plant specimens. It discusses important herbarium collections around the world and includes techniques for staining specimens. The overall document serves as a guide for building and maintaining a herbarium collection.
Plant taxonomy
Taxonomy is the classification of organisms based on their characteristics in order to understand relationships. It began over 300 years ago and was popularized by Linnaeus in the 1700s. Plants are classified into a taxonomic hierarchy of kingdom, division, class, order, family, genus, and species based on shared characteristics. Correct classification and naming of organisms is important for identification and understanding relationships between taxa.
Herbarium
Herbaria are collections of dried plant specimens that are carefully preserved, labeled, and organized according to taxonomic classification systems. Specimens are collected, pressed, dried and mounted on paper to be stored in herbaria. This allows plants to be permanently preserved for scientific study, identification and reference. Herbaria play an important role in developing plant identification resources, documenting geographic distributions of species, and preserving type specimens that are critical for taxonomic research.
Plants organ system
Plants have several major organ systems that allow them to survive and reproduce. These include roots that absorb water and minerals, stems that provide structure and transport nutrients, leaves which perform photosynthesis, and reproductive structures like flowers and seeds. Plant tissues include meristematic tissues that facilitate growth and permanent tissues that carry out specialized functions. Together these organ systems and tissues enable key plant processes and allow plants to sustain life on Earth.
Angiosperm classifications
The document summarizes the history of angiosperm classification from ancient times to modern systems like APG. It describes the early work of ancient Greek and Roman scholars like Theophrastus and Pliny. It then discusses the major historical periods of classification including the Period of Herbalists, Period of Mechanical Systems established by Linnaeus, Period of Natural Systems, and Period of Phylogenetic Systems influenced by Darwin's theory of evolution. Finally, it outlines the modern Angiosperm Phylogeny Group systems from APG I to the current APG IV, which is based on molecular data and recognizes 64 orders and 416 families of flowering plants.
Botany an overview
Botany is the study of plants. It includes the study of bacteria, viruses, fungi, algae, bryophytes, pteridophytes, gymnosperms and angiosperms. Some key points covered in the document include:

Roots
Roots have several primary functions including anchoring the plant, absorbing water and minerals, transporting nutrients, storing food, and reproducing. Most dicots have a taproot system with one main root and smaller branch roots, optimized for support and storage. Monocots have a fibrous root system of many similarly sized roots that maximizes absorption. Adventitious roots develop in unusual locations to aid reproduction or support. Specialized roots include storage, gas exchange, photosynthesis, and parasitic roots. Mycorrhizal and nodular roots form mutualistic relationships with fungi and bacteria respectively.
Plant systematics
This document discusses the key concepts and components of systematics, which includes taxonomy and phylogeny. It covers topics such as:
- The goal of phylogenetic reconstruction and evolutionary history.
- The major parts of systematics including description, classification, nomenclature, and identification.
- Tools for communicating taxonomic information such as keys and scientific names.
- Methods for determining evolutionary relationships including cladistics and cladograms.
- Principles of formal taxonomic naming and types of specimens.
- Uses of keys to identify unknown taxa.
Plant classification
The document summarizes key characteristics of the four main groups in the plant kingdom - bryophytes, pteridophytes, conifers, and angiosperms. Bryophytes include mosses and are small non-vascular plants that reproduce using spores and live in damp environments. Pteridophytes are vascular plants like ferns that can grow larger than bryophytes due to possessing tissues like xylem and phloem. Conifers are gymnosperms that bear naked seeds in cones, while angiosperms are flowering plants that produce fruits enclosing seeds.
Herbarium- Concept ,types and Important
The document discusses herbariums, which are collections of preserved plant specimens used for reference and study. It provides details about what is included in herbariums, such as dried, pressed and mounted plant specimens arranged systematically. Herbariums serve important functions like conserving plant materials and data, aiding teaching and research, and acting as a record of plant diversity over time. The document lists several major herbariums around the world and highlights the Royal Botanic Garden in Kolkata, India as an important herbarium founded in 1787 that contains tropical plants and supports botanical research.
Binomial nomenclature
This document provides an overview of binomial nomenclature, which is the system used to universally name plant species. It discusses how binomial nomenclature was introduced by Linnaeus in 1751 to address issues with common names varying between locations and sometimes referring to different species. The document then explains how binomial nomenclature works, using two names (genus and species epithet), and the advantages it provides. It also outlines the International Code of Nomenclature which standardizes botanical naming, and how this code has evolved over time through different botanical congresses to establish standardized rules.
Nomenclature of fossils
This document summarizes the nomenclature used for naming fossil plants. It discusses the history of naming conventions for plant fossils and how the current Vienna Code provides flexible taxonomic concepts for paleobotanists. Individual plant parts discovered as fossils are often named as form genera to represent detached organs like leaves, stems, or cones. When plant parts can be reconstructed into a whole organism, a binomial name may be assigned. Common plant fossil genera discussed include Lepidodendron and Calamites along with the form genera used to represent their individual parts.
ROOTS
The document outlines the structure and function of plant roots. It discusses the evolution of roots from early vascular plants. There are two main root systems - taproots which develop from a single main root, and fibrous root systems with many branching roots. Primary root tissues include the epidermis, cortex, endodermis, pericycle and vascular tissues. Root growth and development is driven by the apical meristem. Lateral and adventitious roots develop from root primordia. Roots undergo secondary growth and have specialized structures to carry out functions like storage, support and nutrient absorption.
Ethnobotany
This document discusses the field of ethnobotany, which is the study of relationships between plants and humans in particular cultures. It examines how ethnobotanists explore how different peoples use plants for food, shelter, medicine, clothing, and religious ceremonies. Some key figures in the development of ethnobotany are mentioned, such as John Harshberger who coined the term. Different branches of ethnobotany are also outlined. The document emphasizes that ethnobotany requires both botanical and anthropological training to understand cultural plant concepts. Examples of some medicinal plants from South America and India are provided, and the significance of medicinal plants for developing new drugs and protecting human and environmental health is discussed.

The document is intended as an educational guide for those interested in learning about the standards for assigning and determining scientific names of plant taxa.
Monocot vs Dicot
This document discusses the differences between monocot and dicot plants. Monocot leaves typically have parallel venation and dicot leaves usually have netted venation. Monocot stems are usually round and solid while dicot stems are usually quadrangular or cylindrical with vascular bundles. Roots of monocots are fibrous and lack secondary growth while dicot roots have a taproot system and secondary growth.
Inferior ovary
The document discusses inferior ovaries in plants. It defines an inferior ovary as one where the internal wall of the thalamus is fused with the wall of the ovary, so only the style and stigma are visible from above. Flowers with this structure are called epigynous. Examples given are apple, sunflower, cucumber and guava. There are two theories for the development of inferior ovaries - the appendicular theory which proposes the ovary develops from the receptacle appendages, and the receptacular theory or axial theory which proposes the ovary develops from the receptacle itself.

Biodiversit y
Biodiversity refers to the variety of living organisms on Earth, including genetic diversity, species diversity, and ecosystem diversity. It provides both instrumental value through goods and services like food, fuel, medicine, and ecosystem functions, as well as intrinsic value as all organisms strive to grow and reproduce. However, biodiversity is being lost due to factors like habitat loss, overexploitation, climate change, and invasive species. Its conservation is important to protect both its consumptive and non-consumptive uses that benefit humanity.
Microbes as Biocontrol Agents & Biofertilizers.pdf
Microbes can be used as bio-control agents and bio-fertilizers to provide benefits over chemical pesticides and fertilizers. Bio-control uses microbes like fungi, bacteria, and viruses to control pests in a targeted manner. Bacillus thuringiensis produces crystal proteins that are toxic to insect orders like Lepidoptera and act by paralyzing the insect's digestive tract. Biofertilizers contain living microorganisms like Rhizobium bacteria that form symbiotic relationships with plant roots to fix atmospheric nitrogen into an organic form accessible to plants. Organic farming utilizes these biological methods to maintain soil fertility and ecological balance while avoiding synthetic substances.
Introduction to pharmacognosy

It defines biodiversity as the variety of life on Earth, including different ecosystems and the species within them. Genetic diversity refers to genetic variation within and among populations and species. Species diversity includes all life forms from microorganisms to plants and animals. Ecosystem diversity looks at how species interact within biological communities. The document notes that biodiversity is highest in tropical regions and outlines India's status as a mega-diverse nation with many endemic species of plants and animals.

Microbes are ubiquitous and include pathogens that cause disease as well as non-pathogens. While only 3% of microbes are pathogenic, microbes play many essential roles for life from producing oxygen to aiding decomposition. The human body hosts trillions of microbes as part of the normal microbiota. Pioneers like Anton van Leeuwenhoek, Louis Pasteur, and Robert Koch helped establish microbiology through early microscopy and development of germ theory and techniques like pasteurization and Koch's postulates. Careers in microbiology involve studying diverse microbes like bacteria, archaea, algae, fungi, viruses, and their roles in health, disease, ecology, biotechnology and more.

This is a short talk that I gave at the Banff International Research Station workshop on Modeling and Theory in Population Biology. The idea is to try to understand how the burden of natural selection relates to the amount of information that selection puts into the genome.
It's based on the first part of this research paper:

TOPIC OF DISCUSSION: CENTRIFUGATION SLIDESHARE.pptx
Centrifugation is a powerful technique used in laboratories to separate components of a heterogeneous mixture based on their density. This process utilizes centrifugal force to rapidly spin samples, causing denser particles to migrate outward more quickly than lighter ones. As a result, distinct layers form within the sample tube, allowing for easy isolation and purification of target substances.
