basal ovule. As a result of the differing geographical focus of the two revisions, none of the Monoon species recognised by Miquel was specifically included in Polyalthia sect. Monoon by Hooker & Thomson, although it is clear that the latter authors’ application of the sectional name corresponds with the species group that includes M. canangioides (Zoll.) Miq. (= P. canangioides (Zoll.) Boerl.) and M. lateriflorum (Blume) Miq. (= P. lateriflora (Blume) King), which only have one ovule per carpel. Although the name Monoon has very rarely been used at the generic level, several authors have followed Hooker & Thomson in recognising it as a section within Polyalthia (e.g., Fries in Melchior, Nat. Pflanzenfam. 17a II: 1–171. 1959; Sinclair in Gard. Bull. Singapore 14: 149–516. 1955; Van Heusden in Blumea, suppl. 7: 1–218. 1992). In order to maintain consistency of the application of the name Monoon for those species with a single ovule per carpel (as recommended by Mols & al. in Syst. Bot. 33: 490–494. 2008), we have opted to typify the generic name using M. lateriflorum, a species currently known as P. lateriflora. The name Enicosanthum was first validly published by Beccari (l.c.) with the description of E. paradoxum Becc. as the only included species name and hence the type. Thus far 20 names have been published in the genus (IPNI, l.c.), of which 18 are currently accepted (Annonaceae checklist, l.c.). Molecular phylogenetic research has indicated that several sampled Polyalthia species, including P. lateriflora, form a well-supported clade with all sampled Enicosanthum species (Mols & al., l.c. 2004; Xue & al., l.c.). In order to ensure recognition of strictly monophyletic genera, we intend to recognise all the species in this clade under the same generic name, which will unavoidably necessitate the renaming of a large number of species currently classified in Polyalthia. With our lectotypification, application of the principle of priority would require all species in this clade to be recognised under the generic name Monoon; this would require not only the renaming of many Polyalthia species, but also the transfer of all 18 Enicosanthum species. The name Enicosanthum has been very extensively used (e.g., Fries, l.c.; Sinclair, l.c.; Walker in Contr. Gray Herb. 202: 1–131. 1971; Klucking, Leaf Venation Patterns, vol. 1, Annonaceae, 1986; Van Heusden, l.c.; Van Setten & Koek-Noorman in Biblioth. Bot. 142: 1–101 + pl. 1–50. 1992). Conservation of the name Enicosanthum is therefore proposed, enabling its continued use and avoiding the unnecessary loss of a long-established and widely used generic name.
