• species
  • A comprehensive review of each species was not intended but rather a user-friendly guide to quickly find accurate answers to the most obvious questions: Where does this plant originate? (namibiana.de)
  • In order to have as wide a coverage as possible, a summary table of more than 900 species was added, and a few plants have been treated as main species despite a lack of good photographs of flowers or fruits. (namibiana.de)
  • Approximately 60,000 plant species are harvested mainly for medicinal usage in the world. (cites.org)
  • Many medicinal plant species are threatened with extinction through overharvesting, habitat loss, climate change, and illegal international trade. (cites.org)
  • leaf
  • In my talk I will focus on the development of leaf primary vein in the growing leaf primordia of Arabadopsis Thaliana, a plant model system. (syr.edu)
  • In close experimental collaboration with a team of plant biologists, we show that the dynamic modulation of cell mechanical properties based on cell auxin concentration can reproduce primary vein pattern, as observed in growing leaf primordia. (syr.edu)
  • Health
  • The regulatory status of each plant is also given, whether it is listed in one or more pharmacopoeias, including the German Commission E monographs, the new ESCOP monographs of the European Community and the World Health Organisation's series of monographs. (namibiana.de)
  • leaves
  • Plant leaves and their vascular patterns not only provide some of the most impressive examples of complexity in the nature that surrounds us, but they are also a wonderful system for studying developmental dynamics. (syr.edu)
  • global
  • The global reported trade in plants for medicinal purposes alone(customs code HS1211, a subset of the custom codes analysed in the International Trade Centre study)was valued at over USD 3.4 billion in 2014 (United Nations 2016). (cites.org)
  • various
  • Historically, people have collected plants and used them for treating and preventing various symptoms and diseases. (cites.org)
