Besides the Hortus being a beautiful place where visitors can relax and learn more about plants, we also facilitate botanical research. At the botanic garden, our ‘Living Botany’ research group investigates (plant) biodiversity and the relationship between plants and people.

This article discusses the coevolution of several species of the tribe Phyllantheae and moths of the genus Epicephala.

The treasure houses of Leiden's University Library and Naturalis house wonderful historical collections with dried plants and botanical drawings. Tinde van Andel, extraordinary professor of History of botany and gardens, studies these collections.

The largest genus within the Phyllanthaceae family is a group called Phyllanthus L. Recent studies have shown, that Phyllanthus is paraphyletic with the genera Glochidion, Breynia and Synostemon nested within it.

The treasure houses of Leiden's University Library and Naturalis house wonderful historical collections with dried plants and botanical drawings. Professor by Special Appointment Tinde van Andel will be studying these collections. Inaugural lecture 6 January.

The Botany Laboratory is part of the Faculty of Archaeology, University of Leiden. Under the supervision of Dr Mike Field, research is carried out here on archaeo- and palaeo-botanical material including seeds and fruits, pollen and spores, and wood.

Calamus javensis is polymorphic. Morphometry and molecular approach resulted in all names used in the complex are regarded as synonyms of C. javensis except C. tenompokensis, which is retained as a distinct species. One variety is here recognized, C. javensis var. polyphyllus (including C. acuminatu…

The Hortus botanicus Leiden has one of Europe’s largest collections of living plants from the Asian region. This rich resource is no longer the sole domain of botanists. Extraordinary professor Paul Kessler studies what the Hortus botanicus Leiden can offer research, higher education and the public…

Chinese materia medica (CMM), comprising a diverse array of natural substances from plants, animals, and minerals, has been integral to Traditional Chinese Medicine (TCM) throughout history. This study investigates the dynamic evolution of CMM, noting shifts in species for improved therapeutic effects…

The availability of complete plant genome sequences together with the ever increasing amount of data on the molecular, cellular and physiological mechanisms of plant development require mathematical and computational models to obtain a complete overview of and generate new insights into the quantitative…

In this thesis, I targeted the orchid genus Lepanthes, one of the six genera of angiosperms that surpasses 1,000 species in the Neotropics, as a study model to investigate the evolutionary processes that promoted species diversifications.

The haplolepideous mosses (Dicranidae) comprise about 4000 species distributed over a wide range of habitats, with great gametophytic and sporophytic morphological variation. Their monophyly is well supported by the results of several molecular phylogenetic studies, which shed light on their relationships…

My PhD thesis investigates the ecological significance of resistance against drought-induced air bubble formation inside the water conduits of plants (embolism), and the plasticity and functional aspects of stem anatomical traits in woody and herbaceous species.

In my research, I used a comparative wood anatomical approach to address wood evolution of the (largely) tropical flowering plant families Apocynaceae and Sapotaceae.

The study of orchid flowers, fruits, and inflorescences is crucial due to the remarkable diversity of orchid species and their unique adaptations to pollinators and seed dispersers. However, our understanding of the evolution and development of these organs within the orchid family remains limited.

Leiden University regularly confers honorary doctorates, and presents awards and prizes.

This thesis presents the systematics, epidermal defense, and bioprospecting of wild orchids.

To gain more insight into the evolutionary development of orchid flowers and fruits, the orchid species Erycina pusilla was studied. The evolutionary origin of the median petaloid sepal, the callus on the labellum, and the stelidia was studied.

In recent decades, climate change has led to more frequent and severe drought events, causing serious consequences such as increased forest mortality and significant crop yield losses. Understanding how drought affects plants, especially economically important herbaceous species, is crucial for predicting…

In our lives we often have little attention or appreciation for plants, let alone the ones we commonly call weeds. This inattention for plants has been described as plant blindness. The Stoepplantjes project aspires to decrease plant blindness by changing the image of weeds and using citizen science.…

How can we monitor and protect biological and cultural diversity in Suriname best? What can we learn from local knowledge and customs associated with biodiversity? How can we understand current species, acoustical, behavioural, and ecological diversity from an evolutionary perspective? Can we predict…

The oldest university in the Netherlands has produced many well-known scientists. Some of them are known to the wider public; others are perhaps less well known, but their achievements are no less impressive.
