On Whorled Phyllotaxis. III. True and False Whorls

As already pointed out earlier (19, p. 186), in the literature on phyllotaxis relatively small attention has been paid to the whorled systems, the interest usually being centered in the explanation of the curious divergence phenomena of the spiral systems. O JT X J Yet the notion of false whorls is as old as the doctrine of phyllotaxis itself; Brongniart in 1828 wrote about „des verticilles floraux [qui] ne sont pas réellement verticillés” (7, p. 226), and S ch imper wrote in 1829 that whorls in which the leaves are inserted around a single node do not exist, all leaf whorls having a definite succession of their members (17, p. 85).
