The tropics comprise the hottest hotspots of global biodiversity. They contain more than two thirds of vascular plant species worldwide with a density 10 times higher than the European flora. Many well-known and economically important plant taxa such as bananas, cocoa, coffee, and yam are of tropical origin.
The identification of tropical plants is a crucial aspect in conservation biology, systematic, ecological, evolutionary and ethnobotanical research. Because of the high species diversity, the poor exploration of many tropical regions, and the unavailability of regional floras and identification tools, however, identification is often problematic.
The botanical diversity of the tropics is being explored and documented by the Naturalis Biodiversity Center in international projects such as Flora Malesiana, Flora of the Guianas and the Flore du Gabon, involving numerous experts with an in-depth knowledge of the plants and habitats of the tropics. One of the aims of Naturalis Biodiversity Center and Hortus botanicus Leiden is the knowledge transfer of plant diversity. This course has been set up to provide an overview of the most commonly encountered tropical plant families, and the knowledge and tools needed for their identification.
Course objectives: Specialists working at Naturalis and botanical gardens in Amsterdam, Leiden and Utrecht will give the participants an overview of the most commonly encountered tropical plant families, including their key features, characteristic genera, and ecological and economic importance. General introductions to plant morphology, systematic research, plant collection techniques, tropical vegetation types, biogeography and ethnobotanical research will be given.
Through lectures, extensive hands-on practicals and excursions to various botanical institutions in the Netherlands, the participants will learn to recognize more than 40 tropical plant families based on generative (flower and fruit) and vegetative (leaf and bark) characters. The participants will learn to use both identifications keys in traditional Floras and interactive on-line keys. During the practical the participants will be able to examine living, herbarium and alcohol preserved material, and during excursions to the tropical greenhouses of botanical gardens in Amsterdam, Arnhem, Leiden and Utrecht special attention will be paid to collection techniques, biogeography and field characteristics.
Ability to identify tropical plant taxa based on vegetative and generative characters
Knowledge of botanical technical terms (plant morphology and anatomy) used in taxon diagnoses, descriptions and identification keys
Ability to use identification tools (dichotomous and multi-access keys)
Knowledge of collection techniques for plant material
Knowledge of the ecological and economic importance of tropical plant taxa
The course will take place from 10-28 januari 2022.
Mode of instruction
Lectures, demonstrations, excursions
28 January: A final recognition exam, and open questions testing knowledge at the end of the course.
Inspection and feedback on the examination
28 January: After the examination a course evaluation, including attention to the answers and discussion of the exam, will be given, followed by a handout of certificates to those with sufficient marks.
All information of lectures and papers will be available on Brightspace.
Mandatory book: Utteridge & Bramley, the Kew Tropical plant families identification handbook (2021), which can be bought with a discount during the course.
Via uSis. However, register in time (October), because there is a maximum of 15 students from Leiden University. Students from other Dutch universities, international students and staff of the botanical gardens will compete for the remaining 15 positions.
Exchange and Study Abroad students, please see the Prospective students website for more information on how to apply.
Minimum 8, maximum 30 students. Students from other Dutch universities, international students and staff of the botanical gardens will also compete for these positions. Ca. 15 places are available for Leiden University Biology students.
The course will mainly be housed in the Leiden Hortus botanicus.
