Research news:

New research web pages by Shankar Pant and Kunjani Joshi have been published on this website about Nepalese Swertia, a genus used for its medicinal properties. (December 2008)

A field guide in English, Portuguese, or Spanish for the genus Tachia is now available as a free download on this web site. (May 2005)

The genus Wurdackanthus is no more. Phylogenetic analyses by Katherine Gould Mathews and Lena Struwe showed that Wurdackanthus was a paraphyletic unit most closely related to Symbolanthus, so it is now included inside Symbolanthus (Gould & Struwe, 2004; pdf; Struwe & Gould, 2004; pdf). (Jan 2005)

Several new species in Helieae, have been described in recent papers, for example in Symbolanthus (Struwe, 2003; pdf - Bolivia) (Jan 2005)


Macrocarpaea apparata, a new gentian species was named by Jason Grant and Lena Struwe after Harry Potter's adventures (Grant & Struwe, 2003; pdf). Jason has also published several other papers with many new Macrocarpaea species, some with Richard Weaver, see Grant & Weaver (2003) and Grant (2004; pdf). (July 2003, Jan 2005)


A detailed evolutionary analysis of Exaceae with biogeographic implications for the Indian Ocean region, Africa and Madagascar was published by Yong-Ming Yuan and collaborators (Yuan et al., 2003: pdf). (Jan 2005)

The large genus Centaurium, the centauries, has been divided up into 4 genera: Centaurium, Gyrandra, Schenkia, and Zeltnera by Guilhem Mansion (2004; pdf), based on new evolutionary results. It was necessary to split up Centaurium because the old genus included four unrelated groups of species. A paper on the biogeography of this group in tribe Chironieae was also published (Mansion & Struwe, 2004; pdf) as well as a paper on Zeltnera in the Americas (Mansion & Zeltner, 2004; pdf). This means that many of the common weeds in the Centaurium genus around the world now have a new genus name.  (Nov 2004)

Gentiana section Stenogyne has been segregated into the new genus Metagentiana by Ho (2004). Metagentiana is closely related to Crawfurdia and Tripterospermum. (Aug 2004)

7 new species of gentians were recently described from Vietnam by S. Hul (Hul, 2002; in Crawfurdia, Gentiana, and Tripterospermum)
