Revisiting the ancient concept of botanical therapeutics

Mixtures of interacting compounds produced by plants may provide important combination therapies that simultaneously affect multiple pharmacological targets and provide clinical efficacy beyond the reach of single compound-based drugs. Developing innovative scientific methods for discovery, validation, characterization and standardization of these multicomponent botanical therapeutics is essential to their acceptance into mainstream medicine.

Dr. Auzoux's botanical teaching models and medical education at the universities of Glasgow and Aberdeen

In the 1860s, Dr. Louis Thomas Jérôme Auzoux introduced a set of papier-mâché teaching models intended for use in the botanical classroom. These botanical models quickly made their way into the educational curricula of institutions around the world. Within these institutions, Auzoux’s models were principally used to fulfil educational goals, but their incorporation into diverse curricula also suggests they were used to implement agendas beyond botanical instruction. This essay examines the various uses and meanings of Dr. Auzoux’s botanical teaching models at the universities of Glasgow and Aberdeen in the nineteenth century. The two main conclusions of this analysis are: (1) investing in prestigious scientific collections was a way for these universities to attract fee-paying students so that better medical accommodation could be provided and (2) models were used to transmit different kinds of botanical knowledge at both universities. The style of botany at the University of Glasgow was offensive and the department there actively embraced and incorporated ideas of the emerging new botany. At Aberdeen, the style of botany was defensive and there was some hesitancy when confronting new botanical ideas.     

ALMIRA HART LINCOLN PHELPS (1793–1884) AND THE SPREAD OF BOTANY IN NINETEENTH CENTURY AMERICA

Mrs. Phelps was influenced by her older sister Emma Willard, a well known educational reformer, and by Amos Eaton, who helped form her botanical and scientific understanding. Feeling the lack of a suitable botanical textbook particularly for female students who were becoming more prevalant, she wrote, Familiar Lectures on Botany, published in 1829, using her first husband's surname (Lincoln). It quickly became popular and continued to be revised and reprinted through 1869. In 1833, a second botany text for lower level students, Botany for Beginners, appeared. It too, went through many reprintings up to 1891. Mrs. Phelps’ other books and writings on science and education were popular also. The botanical texts were educationally innovative in starting with flower structure using common living examples and integrating morphological and physiological aspects of plants. The Linnaean System was used to classify the “most common native and foreign” plants that were described mainly from Eaton's manuals. Clear figures, often copied from well-known authorities helped to instruct teachers and students. Because of its wide usage, even in later years in competition with the widely used textbooks of Asa Gray and Alphonso Wood, Mrs. Phelps’ books were an important factor in educating many students, especially females, in botany and inducing some of them to have a life-long interest in the science and in teaching it to others. She was, through her writings, a person who helped provide a favorable climate for the developing profession of botany in America.     

Interactive plant identification based on social image data

Speeding up the collection and integration of raw botanical observation data is a crucial step towards a sustainable development of agriculture and the conservation of biodiversity. Initiated in the context of a citizen sciences project, the main contribution of this paper is an innovative collaborative workflow focused on image-based plant identification as a mean to enlist new contributors and facilitate access to botanical data. Since 2010, hundreds of thousands of geo-tagged and dated plant photographs were collected and revised by hundreds of novice, amateur and expert botanists of a specialized social network. An image-based identification tool – available as both a web and a mobile application – is synchronized with that growing data and allows any user to query or enrich the system with new observations. An important originality is that it works with up to five different organs contrarily to previous approaches that mainly relied on the leaf. This allows querying the system at any period of the year and with complementary images composing a plant observation. Extensive experiments of the visual search engine as well as system-oriented and user-oriented evaluations of the application show that it is already very helpful to determine a plant among hundreds or thousands of species. At the time of writing, the whole framework covers about half of the plant species living in France (2200 species), which already makes it the widest existing automated identification tool (with its imperfections).     

Application of nanotechnology for the encapsulation of botanical insecticides for sustainable agriculture: Prospects and promises

This review article discusses the use of nanotechnology in combination with botanical insecticides in order to develop systems for pest control in agriculture. The main types of botanical insecticides are described, together with different carrier systems and their potential uses. The botanical insecticides include those based on active principles isolated from plant extracts, as well as essential oils derived from certain plants. The advantages offered by the systems are highlighted, together with the main technological challenges that must be resolved prior to future implementation of the systems for agricultural pest control. The use of botanical insecticides associated with nanotechnology offers considerable potential for increasing agricultural productivity, while at the same time reducing impacts on the environment and human health.     

WALTER HOOD FITCH AND THE HOOKERS – THE CONTINUING TRADITION OF BOTANIST AND ARTIST COLLABORATION AT KEW GARDENS

Validation of botanical origins and geographical sources of some Saudi honeys using ultraviolet spectroscopy and chemometric analysis

This study aims at distinguishing honey based on botanical and geographical sources. Different floral honey samples were collected from diverse geographical locations of Saudi Arabia. UV spectroscopy in combination with chemometric analysis including Hierarchical Cluster Analysis (HCA), Principal Component Analysis (PCA), and Soft Independent Modeling of Class Analogy (SIMCA) were used to classify honey samples. HCA and PCA presented the initial clustering pattern to differentiate between botanical as well as geographical sources. The SIMCA model clearly separated the Ziziphus sp. and other monofloral honey samples based on different locations and botanical sources. The results successfully discriminated the honey samples of different botanical and geographical sources validating the segregation observed using few physicochemical parameters that are regularly used for discrimination.     

BOTANICAL COLLECTING IN 18TH‐CENTURY LONDON

The correspondence exchanged between Captain John Blake, John Bradby Blake, and their associates offers a valuable insight into the sociable world of Enlightenment botany. By considering these sources alongside the records of other contemporary scholars of botany, this paper examines the composition of the community of plant collectors and botanical scholars with whom father and son were interacting in the 1760s and 1770s. The documents also reveal the ways in which botanical knowledge circulated among the members of these communities. Amateur botany, it turns out, was deeply linked to gardening and to the emerging trade in horticultural plants, yet the contributions made by gardeners and nurserymen have been largely overlooked. In sum, the Blake collection at Oak Spring helps to answer larger questions about the nature of Enlightenment sociability, about diversity within botanical networks, and about the ways in which that social diversity affected botanical collecting.

Neural networks in chemosystematic studies of Asteraceae: a classification based on a dichotomic approach

This paper describes the application of artificial neural nets as an alternative and efficient method for the classification of botanical taxa based on chemical data (chemosystematics). A total of 28,000 botanical occurrences of chemical compounds isolated from the Asteraceae family were chosen from the literature, and grouped by chemical class for each species. Four tests were carried out to differentiate and classify different botanical taxa. The qualifying capacity of the artificial neural nets was dichotomically tested at different hierarchical levels of the family, such as subfamilies and groups of Heliantheae subtribes. Furthermore, two specific subtribes of the Heliantheae and two genera of one of these subtribes were also tested. In general, the artificial neural net gave rise to good results, with multiple-correlation values R>0.90. Hence, it was possible to differentiate the dichotomic character of the botanical taxa studied.     

INTRODUCTION

The Oak Spring Garden Library, a legacy of Rachel Lambert Mellon (1910–2014) and now part of the Oak Spring Garden Foundation, contains the archive of John Bradby Blake (1745–1773), a young trader who worked for the British East India Company in the late 1760s and early 1770s in Canton (Guangzhou) and Macau. The archive provides an unusually detailed insight into Bradby Blake's life and botanical work, including his attempts to send living plants back to England. The archive also contains almost 200 pieces of exquisitely detailed early British‐Chinese hybrid botanical art, which Bradby Blake prepared with a Chinese artist, Mauk‐Sow‐U. With their emphasis on botanical detail and careful depiction of the detailed structure of flowers, these illustrations are as accurate as any produced at this relatively early date in the post‐Linnaean development of botanical science.     

中国植物园展望

In China, a new period of development in the first decaje of the 21st Century with rapid urbanization,was marked by investment in construction of over five billion yuan. At this time of rapid change it is important for botanical gardens to follow three principles, "scientific contents, artistic appearance, and cultural display", so as not to become public parks. The scientific component is important. It is not necessary for every botanical garden to do basic botanical research but they should all be involved in plant conservation issues, especially ex-situ conservation and keep accurate data on their living collections. Although a heavy responsibility this documentation is the foundation and the bottom line of scientific meaning for a botanical garden. Economic plant research, exploring new resources, was a major contribution of botanical gardens historically and remains important for sustainable cities and the national economy of China. Education and ecotourism are important ways for botanical gardens to serve the public displaying the interesting plant collections to enhance relaxation and well-being. It is reasonable to make income through all activities in a botanical garden but this should not be the major goal. It should be understood botanical gardens are comprehensive and multi-functional bodies determined by science, the arts and culture.
