Abstract

Leaves of five forma of Hydrangea macrophylla group listed below were anatomically investigated and many variations were found in the epidermal and mesophyll tissue. (1) Hydrangea macrophylla var. macrophylla forma macrophylla (2) H. macrophylla var. macrophylla forma normalis (3) H. macrophylla var. megacarpa forma megacarpa (4) H. macrophylla var. acuminata forma acuminata (5) H. macrophylla var. angusta forma angusta There was no difference in the anatomical characters between two forma of H. macrophylla var. macrophylla. Their leaves were composed of one-layered epidermis, in which the outline of the cell walls was straight, and ten or more cell-layers of the mesophyll, of which adaxial two-three layers were palisadal. In other three forma, also, the epidermis was one layer of cells, but the outline of cell walls was curved inwardly or outwardly. The palisade tissue was composed of only one layer of cells. It is known that section Hydrangea possesses unicellular hairs with a hillock-like structure at their base (STERN, 1978). Besides the hairs, unicellular hairs without a hillock-like structure at their base were found. These variations are fully expected to have an important significance, when an intra-specific relationship of H. macrophylla or/and an inter-specific one of the genus Hydrangea will be discussed in future.
