Description
Summary:Fifty-one names of plants now recognised as Chlorophytum that are based on type materials from Angola are reviewed. Twenty-three of these names are based on Welwitsch's collections for which there is generally no holotype. All the original materials have been critically reviewed. For eight names, some of the original materials did not match the protologue or comprised several taxa. For nine names, erroneous application of the term holotype is corrected to lectotype ("inadvertent lectotypifications"). For twenty-one names, lectotypifications are provided, including a new lectotype for Chlorophytum limosum and three second-step lectotypifications. A lectotype is also designated for Chlorophytum subpetiolatum based on materials from Mozambique. Eleven new synonyms and six new combinations are proposed (Chlorophytum benguellense, Chlorophytum fernandesii, Chlorophytum molle, Chlorophytum orchideum, Chlorophytum sphacelatum var. arenarium, Chlorophytum ustulatum. Current accepted names are provided for all taxa. Seven accepted taxa are endemic to Angola. Ten names remain unplaced because no material was found.
