  • Erigeron fukuyamae Kitam.

    This variety is distinguished from var. morrisonensis by following points:
    1. Stems longer and usually branching.
    2. Leaves linear to linear-lanceolate.
    3. Heads smaller, 1.2-2 cm in diameter.
    4. Florets usually trisomic: (1) marginal ligulate pistillate, (2) marginal tubular pistillate, and (3) disc tubular bisexual florets mixed.

    Endemic; in mountain regions, 1,500-3,400m.

    Variety morrisonensis is restricted to alpine regions above 3,400 m. Between 2500 and 3400 m, are plants that appear intermediate between var. morrisonensis and var. fukuyamae. These plants have linear-lanceolate leaves and relatively large heads. The heads are sometimes tripmorphic and sometimes not in these intermediates.
