gonium and made the combination, L. carinthiacum) In 1836, how- 
ever, Grisebach, in his preliminary publication upon the Gentianaceae, 
instead of adopting the properly published Lomatogonium, took up for 
the genus the Eschscholtz name but modified to Pleurogyne,? ascribing 
it to Eschscholtz and citing Lomatogonium as a synonym; and this 
name was later used by Grisebach in his more extended work? And, 
although the original form of the name, Pleurogyna, was preferred by 
George Don‘ and has been adopted in Index Kewensis, the name 
Pleurogyne has been in general use up to the present time. In the 
same year, 1836, that Grisebach formally put forward Pleurogyne 
as a genus, Rafinesque published Narketis,> based upon Swertia rotata, 
Gentiana carinthiaca, etc. But, since Pleurogyna was published by 
Chamisso & Schlechtendal only as a synonym for a section of Gentiana 
and consequently, as Professor Briquet says in a letter to the present 
writer, “must be considered as a genus non rite publicatum," and since 
neither Pleurogyne nor Narketis were published as generic names until 
1836, it should be clear that the first properly published name for the 
genus is Lomatogonium A. Br. (1830).
