“…However, there is substantial overlap in trait variation and therefore any distinction on morphological grounds seems rather arbitrary. Likewise, all available cytogenetic and nuclear genomic data on species of this clade indicated the same ploidy level [i.e., 2n = (44)-46 chromosomes (Taylor, 1945;Green, 1968;Briggs, 1970;Dawson, 1995;Kiehn, 2005;Yang et al, 2018;Carré et al, 2021)], except one count supporting tetraploidy in an unresolved Phillyrea taxon collected in Minorca, Balearic Islands (Cardona, 1991). By contrast, there is quite a clear geographic separation among the five taxa (Table 1), each seemingly having colonized different areas, which perhaps justifies Green's geographic concept (1958Green's geographic concept ( , 1963aGreen's geographic concept ( ,b, 1968.…”

“…They also grow on diverse substrates that range from volcanic in Macaronesia, Hawaiian Islands, and Norfolk, to ultramafic in New Caledonia. Similarly, there is a great diversity of sexual system in this small group (Table 2), ranging from hermaphroditism in Nestegis sandwicensis (Sakai et al, 1995), Notelaea (Green, 1968(Green, , 2004, and Picconia (Green, 2004) to androdioecy in 'Notosmanthus' (and in Osmanthus s.s. for that matter; Green, 1958Green, , 1963aGreen, , 1998, Phillyrea (Lepart & Dommée, 1992;Green, 2004), and possibly in Picconia as well (Artega et al, 2006;Ferreira et al, 2011), and even polygamy in New Zealand Nestegis (Green, 1963b;Wagner, Herbst & Sohmer, 1999). Such variability in sexual reproduction is considered a hallmark of lineage diversification and facilitates adaptive radiation (Barrett, 2013).…”

“…for Osmanthus, and Olea excelsa Sol. for Picconia) and there has been a continuous and frequent transfer of species from one genus to another (e.g., Johnson 1957, Green, 1968, which all denotes the complexity of this group. Morphologically, members of the MMP clade can be distinguished from Olea by their inflorescences that are axillary and mostly racemose-decussate, which are usually terminal and cymose-paniculate in Olea (Green, 2004), yet morphological limits are obscure among them.…”

Tackling the complicated infrafamilial classification of the economically important Oleaceae requires a piecemeal approach that addresses generic circumscriptions. Here, focusing on the distinct clade formed by the generic complex Nestegis, Notelaea, Osmanthus, Phillyrea, and Picconia within the subtribe Oleinae, we aim to elucidate their boundaries and relationships and to evaluate their biogeographic history in light of their peculiar disjunct distribution in the Macaronesian, Mediterranean, and Pacific Regions. Based on phylogenomic data from plastid and nuclear DNA of an extensive sampling, the results show six subclades within this generic complex, which are also geographic segregates found in Australia (Notelaea), Hawaiian Islands (Nestegis sandwicensis), Macaronesia (Phillyrea and Picconia), Mediterranean Region (Phillyrea), New Caledonia (Osmanthus section Notosmanthus), and New Zealand (Nestegis s.s.). Accounting for broad morphological overlaps within this clade, we recognize three genera (Phillyrea, Picconia, and Notelaea s.l.), subsuming all Pacific taxa under Notelaea s.l. Molecular dating and biogeographic analyses indicate that this clade originated in Eurasia during the Early Miocene (mean 23.2 Mya, 95% HPD: 23.8 -14.7). Finally, dispersal (rather than continental vicariance) is likely the main explanation for the global, disjunct distribution of this group; with island-hopping and local extinction as the hallmarks of its evolutionary history.

“…While there is some geographic structuring among N. lloydii populations, these two species are not reciprocally monophyletic, suggesting that N. lloydii and N. microcarpa may constitute a single taxon. Notelaea lloydii is described as a multistemmed shrub with linear leaves (Guymer, 1987), while N. microcarpa is described as a tall tree with lanceolate leaves (Green, 1968;Guymer, 1987). Such morphological variation may be a phenotypic response to local environmental conditions and requires further investigation and a detailed morphological analysis to delineate species boundaries.…”

Conservation decision‐making and prioritization of management actions for taxa at high risk of extinction require a clear understanding of systematic relationships and species boundaries. Taxonomic uncertainty surrounds two threatened species of native olive (genus Notelaea) endemic to Australia. Notelaea ipsviciensis is known from only one small population and is listed as critically endangered under Australian and Queensland legislation, while Notelaea lloydii is listed as vulnerable due to its restricted distribution in south‐east Queensland, Australia. Notelaea ipsviciensis occurs in sympatry with N. lloydii, at the only site where it is found, and exhibits intermediate morphology between N. lloydii and Notelaea ovata raising speculation that it is a natural hybrid of the two. To address this uncertainty, we have reconstructed the molecular phylogeny of the genus Notelaea using both single‐gene sequencing and single nucleotide polymorphism (SNP) data. While the chloroplast DNA markers were not found to be informative, the genome‐wide SNPs used in this study have unequivocally resolved the long‐standing question of the hybrid origin of N. ipsviciensis. Results of the phylogenetics and hybrid analyses of SNP data show that N. ipsviciensis is a natural hybrid of N. lloydii and N. ovata, and the taxon's circumscription needs to be re‐evaluated. Our results also revealed unclear species boundaries among numerous other Notelaea species, including the threatened N. lloydii, indicating that further investigation and taxonomic revision may be necessary.

The intensive geographical exploration of the world, starting in the mid eighteenth century, resulted in the discovery of numerous plant species new to science of which many were subsequently introduced into cultivation in Europe. Etienne-Pierre Ventenat (1757-1808) contributed widely to this process. After the end of his curatorial and teaching commitments at Sainte-Geneviève Abbey in Paris he became an active botanist following in the footprints of his mentor Charles Louis L'Héritier de Brutelle (1746-1800). Ventenat was attracted by a trend of his period : publishing magnificent botanical books splendidly illustrated. He published three flower books from 1800 to 1808 on exotic plants recently brought to France from all over the world by various expeditions. Two flower books describe plants cultivated by Jacques-Martin Cels (1740-1806), an influential horticulturist who had built one of the most impressive plant collections of his period at Montrouge, just outside Paris. Another plant lover was Empress Joséphine (1763-1814). After her wedding with Napoléon Bonaparte (1769-1821), she bought in 1799 the splendid estate of Malmaison west of Paris. There the Empress assembled a remarkable collection of exotic plants, largely cultivated in her orangery and the "Grande Serre Chaude". She engaged Ventenat to describe her luxurious collection and the artist Pierre-Joseph Redouté (1761-1841), later known as the "Raphaël des fleurs", to depict the plants. This resulted in the famous flower book Jardin de la Malmaison, a masterpiece of botanical illustration. Ventenat, exhausted, passed away in 1808. His personal herbarium was bought in 1809 by Benjamin Delessert (1773-1847) whose herbarium was later donated to the City of Geneva in 1869. In his three flower books Ventenat treated a total of 343 plant names. A search in the herbaria of Geneva, Paris, Berlin and Madrid resulted in the finding of nearly all the original material relative to these names. A comprehensive list of names is provided here with comments on the origin of the plant material in the context of the explorations of this period, as well as information on typification and currently accepted names. In his three flower books Ventenat validated the names of 208 taxa (207 species and one variety) new to science : of these 67 are still accepted today as published while 52 are basionyms of names currently placed in another genera. Of these 208 names, lectotypification was not needed for 116 and the holotype has been found in G. For the remaining 92 names, 21 previous lectotypifications have been published but 5 of them needed a second-step lectotypification ; 70 new lectotypes have been selected and one neotype. Further comments on the typification of ten species are also provided.
