The line is distinguished by low or very low height and the presence of weak or medium stem pubescence. Leaves are small or medium in size, light green or medium green in color, and have fine or medium dentation. The head is characterized by a small size.
Ray florets are medium yellow in color; anthocyanin coloration of the stigmas is absent. Branching is predominantly apical; the position of the nearest lateral head is above the main one. The line is fertile and produces pollen, which suggests its use in the creation of hybrids.
