形態特徵

• This variety is distinguished from var. morrisonensis by following points:<br> 1. Stems longer and usually branching.<br> 2. Leaves linear to linear-lanceolate.<br> 3. Heads smaller, 1.2–2 cm in diameter.<br> 4. Florets usually trisomic: (1) marginal ligulate pistillate, (2) marginal tubular pistillate, and (3) disc tubular bisexual florets mixed.
• Variety <i>morrisonensis</i> is restricted to alpine regions above 3,400 m. Between 2500 and 3400 m, are plants that appear intermediate between var. <i>morrisonensis</i> and var. <i>fukuyamae</i>. These plants have linear-lanceolate leaves and relatively large heads. The heads are sometimes tripmorphic and sometimes not in these intermediates.
