Development of the inflorescence and paraclades of Actinodium cunninghamii. A. Vegetative meristem before flower production. B. Inflorescence meristem with increased size and changed phyllotaxis (two clockwise and three counterclockwise parastichies in A and a 3/5 set in B). C. Vegetative meristem after flower production exhibiting the same phyllotaxis as before flowering. D. Side view of a transitional zone of an inflorescence with proximal flower buds (f) and distal paraclades (pc) developing in basipetal sequence. Some bracts have been removed in order to visualize the axillary products. E. Inflorescence development showing acropetal flower production. F. Tip of an inflorescence primordium producing the last flower buds. G. After flower production the meristem continues growth and leaf production (l). 1, 2, leaf pairs at paraclades, br, bracteoles below flower, en, enation, m, meristem. Bars: A-C: 50 μm; D, 200 μm; E, F: 100 μm; G: 1 mm.
