Abstract

The structure and the ontogenetic process of the reproductive shoot apex forming a terminal inflorescence ofClethra barbinervis were examined, especially concerning the superficial view of the apex.

The system of contact parastichies is 2+3 in phyllotaxis in the vegetative phase, changing to 5+8 for bract arrangement in the reproductive phase. At the same time the size of the apex is conspicuously enlarged. The size of the foliage leaf primordia in the vegetative phase is larger than that of the bract primordia in the reproductive phase. The radial cell files, which are clear in the vegetative shoot apex, are not recognizable at least in the early stage of the reproductive phase.

The author proposes a close correlation between the appearance of the radial cell files, as well as the construction of the apical sectors, and the sizes of the shoot apex and leaf primordia. It may be proposed also that the construction of the apical sectors is closely correlated with the phyllotaxis.
