Seedlings of invasive plants


This key helps to identify seedlings of invasive plants, so plants can be recognized in an early stage of development. The species included are those of invasive terrestrial plants and/or plants which are introduced as weeds in imported potplants.

A total of 92 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. Several species are also treated in the Key to the invasive terrestrial plants and/or the Key to the Weeds in bonsai plants. This key is also available in French and Dutch.


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.

Thysanoptera Aotearoa (Thrips of New Zealand)

There have been few studies on the thrips of New Zealand. Most of the information presented in this system is derived from two Fauna of New Zealand volumes (Mound & Walker 1982; 1986). However, much of the data in those two volumes was derived from limited amounts of field work, both in space and time. Particularly missing are biological studies on thrips species that are native to New Zealand, with many of these remaining known from very few specimens.

Only for some Thripidae have there been studies on biology and host-plant range. Teulon & Penman (1990) produced outstanding data on the diversity of plants on which Thrips obscuratus breeds. Martin & Mound (2004) explored the host associations of several species, and Martin (2017) provided good data on the host plants of Panchaetothripinae in New Zealand.

For the many species of fungus-feeding Phlaeothripidae there have been no studies on biology or behaviour, although the sexual dimorphism and male polyphenism many such species exhibit suggests the existence of competitive behaviours.
