Bartsia was named after
Johann Bartsch (Latinized as Johannes Bartsius, 1709-1738), a botanist of
Königsberg. The plant was named for him by his associate
Carl Linnaeus, and the genus has been sometimes spelt as Bartschia.[1]
Starbia, an
anagram of Bartsia, is another genus of Orobanchaceae, synonym of Alectra.[2]
The cladogram has been reconstructed from
nuclear and
plastid DNA molecular characters (
ITS, rps16 intron and trnK region).[3][4]
Classification
In 1990, the genus was revised to contain 49 species; 45 of them are
endemic to the
Andes.[5] The most familiar species might be the well-studied Bartsia alpina, which has a
circumboreal distribution, occurring throughout northern regions of the Northern Hemisphere.[6] There are also two
afromontane species, restricted to the mountains of northeastern Africa: Bartsia decurva and Bartsia longiflora. These two plants, B. alpina, and the many Andean species are three distinct lineages, making the genus
polyphyletic.[7][4][8]
As a solution to the problem of Bartsia polyphyly, two taxonomic adjustments have been proposed.
All South American species are reclassified into the new genus Neobartsia.[8] This new name keeps traceability with Bartsia while incorporating information about its New World distribution (in
ancient Greek, νέος, i.e. néos, means 'new').
The two African species Bartsia decurva and Bartsia longiflora are reclassified into the existing genus Hedbergia.[4]
Accepted species names include the following taxa classified according to geographic distribution groups.[9][8]
