Cotoneaster tomentosus in the North Hungarian Mountains
Somlyay Lajos – Sennikov Alexander
Cotoneaster tomentosus (Aiton) Lindl. is considered a montane species of sub-Mediterranean character with a local distribution area restricted to the Transdanubian and the Mecsek Mts in Hungarian literature (Jávorka – Soó 1951, Soó 1966, Bölöni 1999, Bartha et al. 2005, Bölöni 2012). The only record (cliff “Pyrker” at Szarvaskő village, Prodan 1909: 112) of this species from the Bükk Mts (North Hungarian Mountains) is now considered erroneous, neither confirmed by (known) voucher specimens nor subsequent observations (see Vojtkó 2001).
During revision of the genus Cotoneaster in Hungarian Herbaria, however, three specimens of C. tomentosus from the Bükk Mts, labelled by Soó (1943) as “C. integerrima ssp. nigra” (= C. niger (Wahlb. ex Fr.) Fr.), have been detected by us. Although Bölöni (1999: 217) was not able to revise Soó’s specimens, they appeared as a record of C. niger in Vojtkó (2001). In the presence of well-preserved vouchers (see below) that clearly display diagnostic characters of C. tomentosus, and considering the Slovak distribution area of this species (see Hrabétová-Uhrová 1962: 214), the historical occurrence of C. tomentosus in the Bükk Mts, especially at Mt. Bélkő, characterized by its unique flora and numerous relict taxa (e.g. Clinopodium thymifolium (Scop.) Kuntze), is undoubtedly reliable.
Cotoneaster tomentosus (Aiton) Lindl. – Bükk Mts: “in dumetis saxosis mt. Bélkő pr. pag. Bélapátfalva”, R. Soó, 16.VIII.1930 (as “C. integerrima ssp. nigra”) (BP 403677, BP 355680 – rev. Sennikov, 2010; DE, without accession number – rev. Somlyay, 2011).
It is noteworthy that Soó also collected C. integerrimus Medik. on Mt. Békő on the same occasion (as “C. integerrima ssp. nigra”, BP 269920, 292751, 431917 – rev. Sennikov, 2010; BPU 1130 – rev. Somlyay, 2011). Unfortunately, the peak of the mount has almost completely been destroyed through permanent mining during the 20th century. For this reason, the current occurrence of C. tomentosus on Mt. Bélkő is very questionable.
