Notes

Wilson (1999, p. 75) includes this in an appendix of poorly known species. The distinction from S. diversifolia remains unclear as no authentic material has been located. In addition to the type, Ulbrich (1924, p. 682) also cites a sterile specimen from Kenya (Fries 2049) and POWO (see https:// powo.science.kew.org/) records this for the Democratic Republic of The Congo, though the basis for the record is unclear. This is an accepted name in POWO (see https://powo.science.kew.org/) and in the African Plant Database (see https://africanplantdatabase.ch/en/nomen/ specie/81556/hibiscus-keilii-ulbr) but we are not confident that H. keilii is distinct from S. diversifolia (and the ‘carmine’ flowers would place this in subsp. agioxillos ), therefore we refrain from making a new combination here. We key out H. keilii based on the distinctions noted by Ulbrich (1924, p. 682) but further collections are clearly needed to ascertain the status of this entity. If this taxon does belong under S. diversifolia , then the epicalyx features must have been misinterpreted. A possible relationship with S. rostellata should also be considered.
