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)
