Plant Taxonomy

What is the difference between a plant species and a sub-species, and how are those plants related to hybrids, varieties and forms? These questions have often created frustration and confusion between botanists, horticulturists and scientists. Finally there is a detailed video which explains the systems for naming, classifying and identifying plants. Plant Taxonomy: The Universal Language, is a video program which covers many related topics including scientific nomenclature, classification, identification and field botany. The first half of the program starts by introducing viewers to the internationally recognized system of binomial nomenclature developed by Carl Linnaeus(1707-1778). While older models of classification are based on plant morphology, this program also presents new systems based on recent molecular findings. See how plant samples and records are stored in a modern herbarium. Text graphics make it easy for students to grasp the many rules which are used when recording plant names. The second half of the video shows how to develop observation skills for recognizing plant families in gardens and natural environments. Clear and readable text is shown as the narrator presents the terms used to describe flowers and leaves. These terms are repeated as students see how to identify flowering plant families and species. Dichotymous keys are shown alongside video images which help to illustrate the key terms and definitions as they are being narrated. Extensive graphics, clear examples, original music and beautiful photography make this program a powerful resource on this complex yet important topic. Two videos on one DVD. Part 1: 21 min. Part 2: 28 min
