I am interested in the generation and maintenance of genetic, phenotypic and taxonomic diversity.
I have an ongoing research program elucidating the phylogenetic relationships, taxonomy and evolutionary history of Cape Asteraceae or Compositae, particularly the tribes Gnaphalieae (everlastings or immortelles) and Calenduleae (African marigolds, Namaqualand daisies).

Digital identification tool:
A digital interactive key to the Relhania clade of southern African daisies, using Delta-Intkey.
Bronwynne Busch & Nicola Bergh, January 2013
The Relhania clade is a group of about 120 species of mostly southern-African daisies that forms the sister group to the large, global radiation of gnaphalioid daisies.
This interactive key can be started from any character, and features illustrations of all characters, and all aspects of each species including geographic distribution maps.
Install http://delta-intkey.com/win32/intk32.exe and http://delta-intkey.com/testp/intkey.zip, then extract relhania_clade.zip and double click on intkey.ink to launch the key. Please read the introductory text accessible via the top left book icon on the intkey screen before using the key.
Please note that this is a test version of the key. You can help us to improve it by sending comments and suggestions to: N.Bergh -at- sanbi.org.za
