New Names in African Celastraceae and Rutaceae Roy E. GereauMissouri Botanical Garden, P.O. Box 299, St. Louis, Missouri 63166-0299, U.S.A.ABSTRACT. Maytenus masindei Gereau (Celastra-ceae) and Vepris hiernii Gereau (Rutaceae) are pub-lished as avowed substitutes (replacement names)for Maytenus conferta Masinde ex N. Robson andCranzia angolensis Hiern. Key words: Africa, Celastraceae, Cranzia, May-tenus, Rutaceae, Vepris. Although Loesener (1892: 206) failed to providefull and direct reference to a basionym when hepublished the combination Maytenus conferta(Ruiz & Pav6n) Reissek ex Loesener (Celastra-ceae), the citation of "Celastrus Ruiz & Pay., Baill.pr. Parte" in the synonymy of Maytenus on thepreceding page and the parenthetical citation of"Ruiz et Pav." in the new combination constitutean indirect reference to the basionym Celastrusconfertus Ruiz & Pav6n (Fl. peruv. 3: 7. 1802) andsatisfy the requirements of the ICBN Article 32.4(Greuter et al., 2000: 54). The combination wasnever listed in Index Kewensis, although Macbride(1951: 263) and Liesner (1993: 344) used thisname for a species occuring in Peru and Bolivia.The recently published name for a species fromEast Africa is a later homonym of this combinationand thus requires an avowed substitute (replace-ment name).Maytenus masindei Gereau, nom. nov. Re-placed name: Maytenus conferta Masinde ex N. Robson, Fl. Trop. E. Africa (Celastra-ceae): 16. 1994, nom. illeg. Not M. conferta (Ruiz & Pav6n) Reissek ex Loesener, Nat. Pflanzenfam. 3(5): 206. 1892. TYPE: Kenya. Kilifi Dist., Marafa, Luke & Robertson 2498 (holotype, EA not seen; isotypes, K not seen, MO). Robson (1994: 16) ascribed the name Maytenusconferta solely to Masinde, but with no indicationthat Masinde provided the description; as in theICBN Article 46.4, Ex. 17 and 18 (Greuter et al.,2000: 73), the name must be attributed to Masindeex N. Robson. Maytenus masindei is a species en-demic to coastal Kenya and Tanzania, distin-guished from M. heterophylla (Ecklon & Zeyher)N. Robson by thickly coriaceous capsules, veryshort, few-flowered pistillate inflorescences, andusually small, crowded, coriaceous subsessileleaves. Mziray (1992: 68) included Diphasia Pierre inthe synonymy of Vepris Commerson ex A. Jussieu(Rutaceae). Crainzia angolensis Hiern was longtreated as Diphasia angolensis (Hiern) I. Verdoorn(e.g., Gilbert, 1958: 106). Due to the prior publi-cation of Vepris angolensis Engler, an avowed sub-stitute (replacement name) is required to treatCrainzia angolensis as a species of Vepris.Vepris hiernii Gereau, nom. nov. Replaced name: Crainzia angolensis Hiern, Cat. afr. pl. 1: 115. 1896; Diphasia angolensis (Hiern) I. Verdoorn, Kew Bull. 1926: 411. 1926; Vepris angolensis (Hiern ['Verdoorn']) Mziray, Symb. Bot. Upsal. 30(1): 70. 1992, nom. illeg. Not Vepris ango-lensis Engler, Nat. Pflanzenfam. 3(4): 178. 1896; Fagaropsis angolensis (Engler) Dale, Trees and Shrubs of Kenya 99. 1936. TYPE: Angola. Cuanza Norte, Golungo Alto, Sobado de Bumba, rio Quiapoza, Welwitsch 4552 (ho-lotype, BM not seen; isotype, LISU not seen). Vepris hiernii is a shrub or small tree distributedin gallery forests of Angola, Gabon, and DemocraticRepublic of Congo, distinguished from other spe-cies of Vepris in those countries by an isostemonousandroecium and bilocular ovary (diagnostic char-acters of Diphasia).Literature CitedGilbert, (. 1958.
