Notes
Subsp. mannii (fig. 1/5) seems to be restricted to Fernando Po and the Cameroun Republic (Cameroon Mt., Bamenda and the adjacent higher parts of the Bambutos). It differs from subsp. ripicola mainly in the dimensions of the flowers, of which the main features and average measurements are as follows: pedicels 4.9 mm. long; sepals connate at the base and persistent, 1.8 mm. long; petals strongly reflexed, 4.8 × 1.7 mm.; fertile stamens 3.6 mm. long with 1.3 mm. long anthers; sterile stamens (like subsp. ripicola) 3.5 mm. long; fertile gynoecium 3 mm. long; sterile gynoecium 3.5 mm. long. Some difference in ecological requirements must be associated with the noticeably higher altitude records of 915–2600 m. with an average of 1880 m. In the absence of flowers the two subspecies cannot be reliably distinguished, and for this reason all the specimens collected from west of Nigeria cannot be certainly placed. P. mannii replaces P. viridiflorum in the middle and western parts of northern tropical Africa and these closely related species overlap only in Uganda, Kenya and Ethiopia.
