Notes
Kramer has identified some São Tomé material as a probably undescribed species; he also makes the perennial error of referring Stolz’s specimen to Malawi where he never collected. The other São Tomé taxon is O. chinensis var. divaricatum H. Christ in Chevalier in Journ. de Bot., sér. 2, 2: 23 (1909). Type: São Tomé, towards the Pic, after Lagua Amelia, Chevalier 14309 (P, syn.).
