Mononeuria, Minuartia, Arenaria -- groenlandica
As I write July 1, 2024, I note that within the last 30 years, what is now called Greenland Stitchwort (Mononeuria groenlandica) has had at least five different names. i.e., three different scientifc names and two different common names.
Somewhere around 2000, I first learned it as Minuartia groenlandica, or Mountain Sandwort. At the time, that represented a recent scientific name change from Arenaria groenlandica, to differentiate it from a European species. Newcomb's Wildflower Guide (Little, Brown and Company, 1977, p. 276) lists the plant as Arenaria groenlandica.
Gilman's New Flora of Vermont (New York Botanical Garden Press, 2015, p. 281) includes it as Minuartia groenlandica, Mountain Sandwort, as does Ted Elliman's and the then-New England Wildflower Society's Wildflowers of New England (Timber Press, 2016, p. 90).
It's only relatively recently that it has been called Mononeuria groenlandica and Greenland Stitchwort.
GoBotany is still calling it Minuartia groenlandica, rather than Mononeuria groenlandica!

Just another comment on how confusing botanical identification can be, but interesting that while the genus name has changed three times, the species appellation, groenlandica, remains constant! :-D
