| Dianthus superbus var.

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 while the latter
having 3 or 4 couples. By the name of I. Maruyama, the botanist
considers this variety, rupifragus, a survivor of an old type
in a uniquely dry, rocky area. |
