Italian alien species in Caryophyllaceae: nomenclatural remarks Author Iamonico, Duilio Laboratory of Phytogeography and Applied Geobotany, Section Environment and Landscape, Department PDTA, University of Rome Sapienza, 00196 Rome, Italy. text Phytotaxa 2020 2020-06-03 446 5 291 300 http://dx.doi.org/10.11646/phytotaxa.446.5.3 journal article 10.11646/phytotaxa.446.5.3 1179-3163 13878680 Gypsophila elegans Bieberstein (1808: 319) . Neotype (designated here): Caucasus, Terek ad Kafbek, s.d., Bieberstein s.n. (LE 01042983 !) ( Fig. 4 ). Note:— Gypsophila elegans was validly proposed by Bieberstein (1808: 319) in the 1 st volume of his Flora Taurico-Caucasica where a short diagnosis, a detailed description, and the provenance (“Habitat in glareosis torrentis Terek, circa portas caucaficas et alpem Kafbek”) were provided. One specimen was found at LE (code 01042983 ) bears some parts of a single plant, and the original label “ Gypsophila elegans | Terek ad Kafbek” which corresponds to the information given in the protologue by Bieberstein (1808: 319) . Although this specimen is the only one currently deposited at LE, unfortunately no date of collection was reported, and I cannot be sure that this specimen was a pre-1808 addition to the collection. As a consequence I here designate LE 01042983 as the neotype of the name Gypsophila elegans (Art. 9.8 of ICN).
