Abstract. As part of the preparation of a taxonomic revision of Cestrum (Solanaceae) for Flora Mesoamericana eight hitherto undescribed species from Mexico, Guatemala, Costa Rica and Panama were identified. These eight new species are described and illustrated. Affinities of the species are discussed and Global Species Conservation Assessments presented.The new species are Cestrum amistadense A.K. Monro, sp. nov. (Vulnerable) which most closely resembles Cestrum longiflorum Ruiz & Pav., Cestrum contrerasianum A.K. Monro, sp. nov. (Vulnerable) which most closely resembles Cestrum formosum C.V.Morton, Cestrum darienense A.K. Monro, sp. nov. (Near Threatened) which most closely resembles Cestrum morae Hunz., Cestrum gilliae A.K. Monro, sp. nov. (Near Threatened) which most closely resembles Cestrum morae, Cestrum haberii A.K. Monro, sp. nov. (Vulnerable) which most closely resembles Cestrum poasanum Donn.Sm., Cestrum knappiae A.K. Monro, sp. nov. (Near Threatened) which most closely resembles Cestrum acuminatum Francey, Cestrum lentii A.K. Monro, sp. nov. (Near Threatened) which most closely resembles Cestrum johnniegentrianum D’Arcy and Cestrum talamancaense A.K. Monro (Least Concern) which most closely resembles Cestrum laxum Benth.
