Robert Scott's Irish mosses, Dicranum scottianum and Grimmia maritima: a note about their publication

Abstract

In 1803 Robert Scott published an illustrated paper describing two mosses, Grimmia maritima and Dicranum scottianum which he had gathered in Ireland. His paper predates Dawson Turner's Muscologiae Hibernicae spicilegium published in 1804, in which the two species were also described. Thus Scott, and not Turner, was the author of these binomials, and the authorities for the species therefore need to be adjusted thus, Grimmia maritima Sm. ex R. Scott (= Schistidium maritimum (Sm. ex R. Scott) Bruch & Schimp.) and Dicranum scottianum Turner ex R. Scott. Type specimens are discussed, in particular isolectotypes are reported in the herbarium of the National Botanic Gardens, Glasnevin, Dublin (DBN).
