Notes
It is probable that further field study may show that neither of the proposed varieties is valid. The original specimens of Junod, 747, on which J. brachyadenia, Pax & K. Hoffm., is based, belong in some cases to var. platyphylla, Pax, and Nelson, 119, shows the same transition. At the same time, the distinction between var. platyphylla, the type of which Pax has referred to J. Woodii as well as to J. Zeyheri, is quite arbitrary, and the truth appears to be that, exactly as in J. Woodii and in J. natalensis, there is in J. Zeyheri every transition from a lanceolate or ovate-lanceolate or ovate entire leaf to a lyrate- or runcinate-pinnatifid one.
