Premise of research. The pantropical magnoliid family Lauraceae has an extensive macrofossil record that dates back to the Early Cretaceous. However, flower anatomy among extant species is relatively poorly known. We investigate flower structure and development in six Neotropical genera to elucidate the homologies of the floral parts, especially the prominent appendages that occur on the filaments of the inner fertile stamen whorl in some species.

Methodology. We used SEM and LM to examine flower organization and development in 11 species of six genera (Aniba, Cryptocarya, Endlicheria, Licaria, Nectandra, Ocotea) and flower vasculature in two species (Cryptocarya moschata and Ocotea prolifera).

Pivotal results. All the flowers examined are typical of Lauraceae: they are very small and possess two whorls of tepals that are similarly vascularized, with three bundles each (resembling bracteopetals), multiple androecium whorls, and a single carpel. Variation exists in some characters, especially in the androecium. A fourth (innermost) androecial whorl is present as staminodia in some species. The prominent stamen appendages are highly vascularized.

Conclusions. The presence of three vascular bundles supplying both outer and inner tepals supports their potential homology as bracteotepals. Floral vasculature also indicates that the staminodia of the fourth androecial whorl are derived from stamens. A potential homology between the stamens and appendages remains debatable, because existing evidence is contradictory.

Cuticular features potentially offer valuable information on phytotaxonomy, especially for plants that are difficult to classify or identify. Cryptocarya is one such difficult and poorly known genus, and we investigated its cuticular features to evaluate their taxonomic implications. We examined cutinized leaf epidermis and the stomatal complex for 21 species from Peninsular Malaysia, Thailand and Indo-China, as well as one species endemic to Borneo and one to Sumatra, and compared features among members of this group, between this group and congeners in the other countries, and between this group and the other genera of Lauraceae. Many of the Cryptocarya species studied have straight to slightly curved anticlinal epidermal walls and butterfly-shaped stomatal ledges, although some variation was seen in the ornamentation of the periclinal epidermal walls and the appearance of the stomatal complex. Based on these results, we recognized four groups and two subgroups among the South-east Asian species. Comparison with congeneric taxa in the other countries indicates that butterfly-shaped stomatal ledges are often shared among the species across the regions. However, no cuticular features occur exclusively in any of the species groups of Cryptocarya studied here, nor in the genus as a whole. We consider that cuticular features are useful in the recognition of infrageneric groups within Lauraceae, bearing in mind that they might have evolved in parallel in different genera.

An account of the genus Hexapora (Lauraceae) is presented. It comprises morphological descriptions of the genus and species, a provisional IUCN conservation assessment, ecological information and taxonomic notes. The morphology of the genus is compared to that of a number of possible close relatives, leading to the conclusion that it most likely belongs within the Beilschmiedia clade, and is likely closely related to Sinopora.

It describes a new species of Lauraceae for the Neotropics, southeastern Brazil, São Paulo and Rio de Janeiro. Ocotea koscinskii Baitello & Brotto is an unisexual species very similar to Ocotea dispersa (Nees) Mez, but differs in particular by the globular shape of the fruit, no remaining tepals at the cupule of the fruit and thyrso-paniculate inflorescence. They still differ by occurrences in different strata when coexist in ombrophilous forests, respectively canopy and understory.

Three endemic new species of Cryptocarya R.Br. are described from New Caledonia.  Cryptocarya adpressa Munzinger & McPherson, sp. nov., is a small-leaved, pinnately veined species resembling species such as C. leptospermoides Kosterm. and C. gracilis Schltr., but differing most notably in its persistent and strongly appressed indument of the inflorescence.  Cryptocarya barrabeae Munzinger & McPherson, sp. nov., resembles C. pluricostata but can be distinguished most easily by its elliptical leaf shape and longer, straighter indument.  Cryptocarya chrysea Munzinger & McPherson, sp. nov., resembles C. guillauminii Kosterm. in its ovate, densely and persistently pubescent leaves with ascendant lateral veins, but differs most notably in its prominently lenticellate stems and abaxially golden leaves. All three new species are trees occurring in dense humid forest. Two are restricted to non-ultramafic substrate while C. chrysea, sp. nov., occurs on both substrates. They are all known from at least three protected areas, and do not appear to be threatened; thus they are all assigned a preliminarily Least Concern IUCN status.

Earlier studies indicated that the genus Nectandra, currently the second-largest genus of the Neotropical Lauraceae, might be diphyletic in its traditional circumscription, but the evidence was not quite conclusive. Our phylogenetic analyses based on nuclear (ITS) and chloroplast (psbA-trnH) sequences of 45 Nectandra species as well as 42 representatives of 18 genera of the core Lauraceae (Ocotea complex, Laureae, Aiouea, Asian Cinnamomum and Persea groups) confirm the suspicion that Nectandra is diphyletic. The two groups, Nectandra s.str. and the N. coriacea group, are each well supported in the maximum parsimony and Bayesian analyses, but they are not sister to each other. Nectandra s.str. is sister to Pleurothyrium, and the clade including Nectandra s.str. and Pleurothyrium is very likely closer to the dioecious taxa of the Ocotea complex. The N. coriacea group, on the other hand, appears to be closer to bisexual taxa known as the Ocotea helicterifolia group. In addition, Nectandra s.str. is characterized by a large deletion in the psbA-trnH spacer compared to all other core Lauraceae, including its sister group Pleurothyrium. Considering these facts, Nectandra cannot be maintained in the traditional sense. We therefore transfer the species of the N. coriacea group to the oldest generic name applied to this group, Damburneya . On the basis of fossil records from the American subcontinents and in accordance with previous phylogenetic and molecular clock studies we suggest a scenario of a climate-driven migration from North to South America, with a subsequent rapid radiation of Nectandra s.str. in South America.

Species-level relationships within the pantropical, largely rainforest genus Cryptocarya R.Br (Lauraceae) and allied groups have long been problematic. Here, we utilise nuclear RPB2 and plastid trnL–trnF sequence data to reconstruct the phylogenetic relationships among Australian Cryptocarya species. We relate our findings to the previous two disparate attempts to resolve species-level relationships on the basis of traditional taxonomic tools. Our results showed that an early diversification gave rise to two lineages present in Australia and globally. The loss of cataphylls (bract-like leaves in seedlings) seems to be a derived state only found in the larger of these two clades. Ruminate cotyledons is another potentially informative character; however, it is highly likely that this condition arose through convergent or parallel evolution. Little or no molecular variation was observed between many species, which suggests recent diversification. Furthermore, the close relationships between species from two geographically disjunct centres of rainforest diversity within Australia suggests that loss of between-region connectivity is recent. A global revision of the group, incorporating molecular analyses and seedling and fruit morphology, is needed to untangle the complex evolutionary relationships within this genus.

Tropical and subtropical amphi-Pacific disjunction is among the most fascinating distribution patterns, but received little attention. Here we use the fossil-rich Cinnamomum group, a primarily tropical and sub-tropical Asian lineage with some species distributed in Neotropics, Australasia and Africa to shed light upon this disjunction pattern. Phylogenetic and biogeographic analyses were carried out using sequences of three nuclear loci from 94 Cinnamomum group and 13 outgroup samples. Results show that although there are three clades within a monophyletic Cinnamomum group, Cinnamomum and previously recognized subdivisions within this genus were all rejected as natural groups. The Cinnamomum group appears to have originated in the widespread boreotropical paleoflora of Laurasia during the early Eocene (ca. 55 Ma). The formation and breakup of the boreotropics seems to have then played a key role in the formation of intercontinental disjunctions within the Cinnamomum group. The first cooling interval (50–48 Ma) in the late early Eocene resulted in a floristic discontinuity between Eurasia and North America causing the tropical and subtropical amphi-Pacific disjunction. The second cooling interval in the mid-Eocene (42–38 Ma) resulted in the fragmentation of the boreotropics within Eurasia, leading to an African–Asian disjunction. Multiple dispersal events from North into South America occurred from the early Eocene to late Miocene and a single migration event from Asia into Australia appears to have occurred in the early Miocene.
