Nomenclature Notes and Typification of Names in Dracaena (Asparagaceae, Nolinoideae)

Abstract

Two new names, Dracaena neoparviflora and Dracaena ridleyii are proposed as replacement names for the illegitimate names D. parviflora Baker, and D. nutans Ridl., respectively, the latter being a later homonym of D. parviflora Willd. ex Schult.f., and D. nutans H.Jaeger. Lectotypes are designated for D.cambodiana, D. interrupta (synonym of D. camerooniana), D. oddonii (synonym of D. camerooniana), D. cantleyi, D. cinnabari, D. cuspidibracteata (synonym of D. congoensis), D. haemanthoides, D. litoralis (synonym of D. braunii), D. parviflora, D. novoguineensis, D. nutans, D. petiolata, D. reflexa var. linearifolia, D. reflexa var. angustifolia, D. steudneri, D. tessmannii (synonym of D. mannii), and D. viridiflora. The second-step lectotypications are made for D. camerooniana, D. bushii, D. glomerata, D. papahu (synonym of D. steudneri), D. talbotii (synonym of D. bicolor), D. vaginata (synonym of D. viridiflora), and D. xiphophylla. A neotype is designated for the name Aletris arborea (basionym of D. arborea).
