BOTANICAL NOTES 487Hieracium coldei Szeląg was described from the Hargita Mts in the Eastern Carpathians in Romania (Szeląg 2006a). Only two locations of the species were known so far, both near Băile Tuşnad: Mt. Piatra Şoimilor (locus classicus) and Mt. Cetăţii (Mt. Vártető in Hungarian) (Szeląg 2006b). During further study of the genus Hieracium in the Car-pathians I found two new stations of H. coldei recently.The ﬁ rst station is on Mt. Tomeasa in the Ţarcu Mts (Southern Carpathians). At ﬁ rst I did not identify the Mt. Tomeasa plants as H. coldei, the Hargita Mts stations of which are 300 km dis-tant from the Ţarcu Mts (Fig. 1). The distinctness of the plants from Mt. Tomeasa was suggested by their tetraploid chromosome number (Ilnicki & Szeląg 2011 as Hieracium sp. ‘Mt. Tomeasa’), while H. coldei in the Hargita Mts is triploid (Szeląg 2006a).It was only when the transplanted living plants from Mt. Tomeasa could be observed in garden conditions that I found them to be morpho-logically identical with H. coldei of the Hargita Mts. Also very helpful were molecular analyses (AFLP), which showed no differences between the two groups, their different ploidy level notwith-standing (Ronikier, Cieślak & Szeląg unpubl.). Such a lack of genetic distinctness between geo-graphically isolated populations was found previ-ously in agamospermous H. silesiacum E. Krause (Ronikier & Szeląg 2008), which is tetraploid over its whole range, however (Chrtek 1996; Chrtek at al. 2004; Szeląg 2004; Mráz 2005; Ilnicki & Szeląg 2011).I found a record of another new location of H. coldei in the Babeş-Bolyai University Herbarium in Cluj-Napoca (CL), where I revised two sheets of plants collected in the Calimani Mts (Kelemen in Hungarian) in the Eastern Carpathians in 1942 by Zoltán Zólyomi and determined by E. I. Nyárády as H. sparsum subsp. borbasii (R. Uechtr.) Zahn (Fig. 2). This station was not included in Flora Republicii Populare Romîne (Nyárády 1965).NEW CHOROLOGICAL DATA ON HIERACIUM COLDEI (ASTERACEAE)ZBIGNIEW SZELĄGZbigniew Szeląg, Institute of Botany, Jagiellonian University, Kopernika 31, 31-501 Kraków, Poland; e-mail: azszelag@wp.plFig. 1.

Specimen of Hieracium coldei Szeląg from the Calimani Mts (CL 511279).BOTANICAL NOTES 489Based on label data, in 2009 I tried to re-ﬁ nd the H. coldei in the Calimani Mts., but to no avail.Until now, the only representative of Hier-acium sect. Cernua R. Uechtr. in the Calimani Mts was H. kotschyanum Heuff. discovered by Mária Höhn in the Ungurasul Mare valley in 1992 (Höhn 1998). Recently the record’s author kindly allowed me to examine the specimens she collected. It is a very interesting isolated locality which I did not include (due to the lack of available material for identity conﬁ rmation) on the distribution map of H. kotschyanum (Szeląg 2006b).NEW LOCALITIES OF HIERACIUM COLDEI: 1 – Southern Carpathians, Ţarcu Mts, Mt.
