| Popis: | In the southern Julian Alps under the northwestern ridge of Kobilja Glava above the pasture of Lom and on the slopes of Krikov Vrh between pastures of Lom and Kuk (Podkuk), on stony shady pasturelands and in limestone and dolomite rocks at elevations ranging between 1,100 and 1,200 m, two forms of auricula ( Primula auricula ) occur side by side. The more common specimens with bright (deep) yellow flowers are accompanied and outnumbered by plants with slightly smaller stems and distinctly pale, lemon-coloured flowers. Although Primula auricula as a species boasts impressive variability in the size and shape of leaves and their meal covering, as well as in the size and colour of flowers, we have not observed populations with such distinctly pale yellow flowers anywhere else in Slovenia. The taxa described elsewhere in the distribution area of Primula auricula s. lat. (including those that supposedly belong to Primula lutea ) are distinctly different from the studied auriculas, at least in terms of flower colour. We infer that they are a new variety, Primula auricula var. tolminensis (the Tolmin auricula), but will have to conduct further research to corroborate this conclusion. In this paper we describe its sites and current distribution. Key words : flora, taxonomy, infraspecies variability, phytosociology, Primula auricula , Kobilja Glava, Julian Alps, Slovenia Izvlecek V južnih Julijskih Alpah, pod severozahodnim grebenom Kobilje glave nad planino Lom in na pobocjih Krikovega vrha med to planino in planino Kuk (Podkuk) na kamnitih osojnih pasnikih in v apnencastem in dolomitnem skalovju na nadmorski visini med 1100 m in 1200 m skupaj rasteta dve obliki lepega jeglica ( Primula auricula ). Poleg obicajno živo (temno) rumeno cvetocih primerkov, ki so v manjsini, prevladujejo rastline z nekoliko manjsimi stebli in cvetovi, ki imajo izrazito svetlorumeno, limonasto barvo. Ceprav je za vrsto Primula auricula znacilna velika variabilnost glede velikosti in oblike listov in njihovega poprha, kot tudi glede velikosti in barve cvetov, takih izrazito svetlorumeno cvetocih populacij drugje v Sloveniji do zdaj nismo opazili. Tudi taksoni, ki so opisani drugod v obmocju areala vrste Primula auricula s. lat. (tudi tisti, ki naj bi pripadali vrsti Primula lutea ) se vsaj v barvnem odtenku cvetov od preucenih avrikljev ocitno razlikujejo. Sklepamo, da gre za novo varieteto Primula auricula var. tolminensis, slovensko jo imenujemo tolminski jeglic, kar pa bomo morali v nadaljnjih raziskavah se potrditi. V prispevku opisujemo njena rastisca in do zdaj znano razsirjenost.
