Notes on the typification of the names Utricularia bremii Heer and U. intermedia Dreves & Hayne (Lentibulariaceae) Author Astuti, Giovanni Author Peruzzi, Lorenzo text Phytotaxa 2018 2018-05-21 350 2 172 176 http://dx.doi.org/10.11646/phytotaxa.350.2.7 journal article 302390 10.11646/phytotaxa.350.2.7 a4505964-713a-4914-8f91-1b99654980e4 1179-3163 13702188 Utricularia bremii Heer in Koelliker (1839: 142) Type ( lectotype , first-step designated by Meister 1900: 23 , second-step designated here):— SWITZERLAND . Katzensee , 26 June 1836 , Bremi s.n. ( ZT !; Fig. 1 ) . Note on typification :—In the protologue (Koelliker 1839), Heer quotes a collection made by Bremi in Katzensee (“In torfmooren selten. Am Katzensee, Bremi” [Rare in peat bogs. At Katzen Lake, Bremi]). Hence, O . von Heer did provide neither a collection date nor an indication that can unequivocally refer to a single specimen considerable as the holotype , as regulated by Art. 9.1 of the ICN ( McNeill et al. 2012 , see also McNeill 2014 ). Consequently, any specimen collected by Bremii before 1839 in Katzensee could be considered as original material. Meister (1900) , in a study concerning the European Utricularia species , reported a list of studied herbarium specimens, among which we can find, listed as the first for U. bremii , the following indication: “ Katzensee: Bremi 26 Juni 1836 , Originalexemplare ” [Katzen Lake: Bremi June 26 th 1836 , original specimens]. It should be noted that the word “ exemplare ” is plural, thus indicating a gathering of more specimens. In accordance with Art. 9.22 of the ICN ( McNeill et al. 2012 ), only for lectotypifications after 1 January 1990 the specification of the herbarium where the type is conserved is needed. Accordingly, that of Meister (1900) clearly represents a first-step lectotypification (Art. 9.17, Ex. 12 of the ICN , McNeill et al. 2012 ). Starting from this consideration, we tried to locate the collection(s) indicated by Meister (1900) , and later also quoted by Taylor (1989) , in the herbaria were Heer’s material is conserved ( Z , B , GZU , K , HAL , and LE ; herbarium acronyms follow Thiers 2018 ) and in other Swiss herbaria ( ZT , G , NEU , CHUR , LUG , NMLU , NHMF and HKGL ). We only found a single specimen of U. bremii , in Zürich ( ZT ! see Fig. 1 ), matching the indication given by Meister (1900) . This specimen is designated here as lectotype in a second-step lectotypification (Art. 9.17, Ex. 12 of the ICN , McNeill et al. 2012 ). It fully agrees with the current circumscription of the species (see e.g., Astuti & Peruzzi 2018 ; Bartolucci et al. 2018 ).
