VASCAN lists Saxifraga tricuspidata var. subintegrifolia (Abromeit) Polunin,
but Polunin published this name at the rank of forma in 1938; the basionym, by Abromeit, was published as a variety in 1899; this is cited in Polunin's publication: Flora of the Southampton Island; J. Bot. vo. 76, pg. 100

The error came from the cited paper, DeChaine 2014: he interverted authorship for var. subintegrifolia Abrom. and f. sub. (Abrom.) Polunin. I have corrected authorship to Abromeit
