BIODIVERSITY REFERENCE


Index to the kingdom PLANTAE



As allowed by the current ICBN (see classification), "phylum" is used instead of "division". Ranks below phylum are used selectively here and are not comprehensive.

The Rhodophyta are accepted here as part of the plant kingdom rather than being in the Chromista (or Protoctista). A good review was provided by Ragan & Gutell (1995).
The classifications of the Rhodophyta and Chlorophyta used here follow van den Hoek et al. (1995). Some other authors prefer a broader view of the class Chlorophyceae. Orders in the Magnoliophytina now follow Stace (2010).

Image links

Mosses and Liverworts in Wales
(Alan Hale)
Excellent set of pages on Welsh bryophytes, also with good habitat descriptions.

Photographs of liverworts
(D.S. Rycroft, University of Glasgow)
Some nice photographs, mostly Scottish.

Flora of Europe: a photographic herbarium
(A.Voswinkel)
Photographs of European wild flowering plants.

Wild Flowers of the British Isles
(Peter Llewellyn)
Excellent and important reference site for photographs of British flowering plants, also with links to companion sites for Europe and Australia.

Floral Images
(J.R. Crellin)
"This site is all about flowers that grow in North-Western Europe - particularly the wild flowers of the British Isles." A large collection of photographs (also including a selection of bryphytes, lichens and fungi), organised by colour and by geography as well as by systematics and alphabetically. A valuable British resource.

British Wild Flowers
(John Somerville)
Another major compilation of photographs of British wild flowers, with contributions from other photographers. However, contributions in the more critical genera need to be vetted more carefully and the index seems to be common names only. The display is IE specific, with page arrangements incorrectly shown in Firefox without an addon being installed (so, based on my own current user statistics, that's about 40% of visitors who will not be able to see the site properly). On the other hand, there is a fine set of reference photographs for anyone interested in microspecies of Rubus (bramble) – a specialised but very valuable resource.

Irish Wildflowers
(Jenny Seawright)
A beautifully designed, authoritative and highly recommended site with many, many photographs carefully chosen to show key features. If only other websites were this good!

Belles Fleurs de France
(Erick Dronnet)
A large site with photographs and descriptions of the French flora.

University of Wisconsin-Madison: Plant Systematics Collection
Many images of American plants.

A Digital Flora of Newfoundland and Labrador Vascular Plants
(The Provincial Museum of Newfoundland and Labrador)
A beautiful site with many, many stunning images, including many species that we have in Britain.

Gallery of Connecticut Wildflowers
(Connecticut Botanical Society)
A good site for descriptions and illustrations of a large selection of American species – a valuable web flora.

Galleria Carnivora
An excellent and comprehensive if slightly quirky archive of photographs of carnivorous plants. Long one of my favourite sites.
