Notes on African Euphorbiaceae: XIV

Abstract

Cephalocroton is reported as new to West Africa. In Croton, a reduction to synonymy is made and new records are reported for Kenya and Somalia. In Cyathogyne, a new record is also reported for Somalia. In Drypetes a new variety is described from Kenya. In Erythrococca, a new record is reported for Mozambique, and a new species is described from Somalia. In Jatropha a new varietal combination is made, a new record is reported for, and a new species described from, Somalia. In Mallotus, a forma is upgraded to the varietal level, and is recorded as new for Mozambique. In Margaritaria a new forma is described. In Neoholstia a new varietal combination is made. In Neopalissya, two new subspecies are described, one for Zimbabwe and one for Tanzania, the latter constituting a new record of the genus for Tanzania. In Phyllanthus, two new records are reported for Mozambique, and one for Kenya. In Ricinus, further information is reported concerning the alleged quellgebiet of this taxonomically rather isolated monotype. In Sapium a new variety is described from Angola and a remarkable brace of colligenda from Tanzania are tentatively attributed to it. In Sibangea, a description is amplified. In Tragia, a lectotype is chosen for a Linnean species. These have all come to light during routine naming of African Euphorbiaceae and the consequent updating of the account of the family for the Flora of Tropical East Africa.
