Ptilotrichum emarginatum Boiss. in Ann. Sci. Nat., Bot. ser. 2, 17: 160. 1842.
Bornmuellera emarginata (Boiss.) Rešetnik in Phytotaxa 159: 299. 2014.
Type: “[Aucher-Eloy] N. 288, mons Delphi Eubeae”.
Holotypus: GREECE: “in Mte Delph. Euboea”, s.d., AucherEloy 288 (G-BOIS [G00332420]; iso-: BM [BM000750102], G [G00371850], K [K000720736], P [P00835134, P00835135, P00835136]) (Fig. 21, p. 113) .
Notes. – None of the three sheets at P was annotated by Boissier, and the duplicate at G is part of the Moricand’s herbarium. Therefore, the treatment of the G-BOIS sheet as the holotype is fully supported (Fig. 21, p. 113).
The species has been known in Leptoplax O.E. Schulz for over 80 years since it was established by SCHULZ (1933), but molecular phylogenetic studies lead to its transfer to Bornmuellera (see REŠETNIK et al., 2013, 2014).
