Key to the weeds in imported bonsai plants in Europe

Introduction

This key is an identification tool for weeds that are introduced in Europe as they are imported as weeds in bonsai or other potplants. As many potplants are produced in Asia and South America, many common weeds in those regions are included. The species treated in this key do not necessarily have invasive treats and some will not survive a European winter.

A total of 136 species is included. All features are illustrated with botanical drawings so that no knowledge of botanical terms is needed, basic knowledge of plant morphology, however, is helpful. Distinguishing characters have been added for certain groups of closely related species. The keys link to complete species descriptions on the Q-bank – Plants website. All species are well illustrated by photographs showing distinguishing characteristics or invaded sites. The key is regularly updated with new species and new photographs. This key is also available in French and Dutch.

Q-bank

Q-bank – Comprehensive databases on plant pests and diseases covers the following organism groups that contain quarantine organisms:

  • Fungi
  • Bacteria
  • Invasive Plants
  • Nematodes
  • Arthropods
  • Phytoplasma’s
  • Viruses and viroids

The databases are curated by internationally known specialists and contain specimen-based information including molecular data. The website offers the possibility to blast, in single- or multi-locus mode, sequences for identification.

Key to the invasive terrestrial plants in Europe

Introduction

This key helps to identify the major invasive terrestrial plants in NW Europe. Invasive are those species that pose a threat to the biodiversity of the ecoregion. Species included are both those that already are known to be invasive in this region, as well as species known to be invasive elsewhere in comparable climatic regions. Moreover, look-alikes are included to distinguish closely related taxa. A total of 140 species is included. All features are illustrated with botanical drawings so that no knowledge of botanical terms is needed, basic knowledge of plant morphology, however, is helpful. The keys link to complete species descriptions on the Q-bank – Plants website. All species are well illustrated by photographs showing distinguishing characteristics or invaded sites. The key is regularly updated with new species and new photographs. Species that are imported in Europe as weeds in potplants are treated in a separate key. This key is also available in French and Dutch.

Seeds of invasive plants

Introduction

This key is an identification tool for seeds of invasive plants. The choice of species was based on an extensive survey of seeds and seed mixtures in trade, where the seeds of these invasive species were found as contamination.

A total of 143 species is included. All features are illustrated with botanical drawings so that no knowledge of botanical terms is needed, basic knowledge of plant morphology, however, is helpful. The keys link to complete species descriptions on the Q-bank – Plants website. All species are well illustrated by photographs showing distinguishing characteristics or invaded sites. This key is also available in French and Dutch.
