Dianthus superbus var.
rupifragus is a perennial inhabiting a dry, rocky area. It closely
resembles another variety, that is, D. superbus var. longicalycinus.
With the former, the stem to set flowers, not erecting, extends
sideways, the leaves having a powdery tinge, the flower hairy
inside, the petals a bit more deeply split. Another difference is
that it has two pairs of bracts. In contrast, the latter has 3 or 4
couples. Iwao Maruyama considers this variety, rupifragus, a
survivor of an old type in a uniquely dry, rocky area. Bloom time:
June-September. |
