Significance Large floristic datasets that purportedly represent the diversity and composition of Amazon tree flora are being widely used to draw conclusions about patterns evolution plant diversity, but these fundamentally flawed in both their methodology resulting content. We have assembled a comprehensive dataset Amazonian seed species from published sources includes falsifiable data based on voucher specimens identified by taxonomic specialists. This growing list should serve as basis...
suprageneric classifications of Lauraceae and the characters used in these are briefly concluded that androecial Cassytha, other including all genera.The latter group is divided into three tribes, ne Lau ureae, Perseeae, Cryptocaryeae, based on wood bark anatomy inflorescence structu form a large, predominantly tropical family trees shrubs, with exception an herbaceous parasite.The best represented American Asian tropics, has also rather large number species Australia Madagascar, but poorly...
The Persea group (Lauraceae) has a tropical and subtropical amphi-pacific disjunct distribution with most of its members, it includes two Macaronesian species. relationships within the are still controversial, intercontinental disjunction not been investigated extensive sampling precise time dating. •ITS LEAFY intron II sequences 78 species nine other Lauraceae were analyzed maximum parsimony Bayesian inference. Divergence estimation employed Markov chain Monte Carlo method under relaxed...

We used the chloroplast gene ndhF to reconstruct phylogeny of moonseed family (Menispermaceae), a morphologically diverse and poorly known cosmopolitan dioecious, primarily climbing plants. This study includes worldwide sample DNA sequences for 88 species representing 49 70 genera all eight traditionally recognized tribes. Phylogenetic relationships were estimated, Shimodaira–Hasegawa test was compare likelihood alternative phylogenetic hypotheses evaluate monophyly tribes currently in use....
Abstract The delimitation of genera within the Persea group (Lauraceae) has always been controversial. In an attempt to resolve phylogenetic lines this group, we analyzed ITS sequences 61 species and 30 other Lauraceae. Several traditional or subgenera form wellsupported groups, viz., subg. Eriodaphne, Machilus, , Alseodaphne including Dehaasia . included Phoebe two clades that are unresolved with respect However, Eriodaphne (together Macaronesian Apollonias barbujana ) forms one basal...
A phylogenetic analysis based on nuclear ITS and plastid trnK intron sequences confirms that Dahlgrenodendron, Sinopora, Triadodaphne, Yasunia are members of the Cryptocarya group, as expected from morphology. Dahlgrenodendron South Africa is sister to Aspidostemon Madagascar. Triadodaphne inaequitepala nested within Endiandra (both Australasia), America among American Beilschmiedia species. Sinopora a member clade, but its precise position still uncertain. Among large genera clearly...

In English, English and French abstracts.Two identification keys to the based on or fruiting specimens are provided. For each genus diagnostic characters, estimates species numbers, recent literature additional notes included. Eight Ravensara Sonn. transferred Cryptocarya R.

Pucara leucantha is transferred to Stenomesson as leucanthum based on the phylogenetic position of resolved by nuclear and plastid DNA sequences. An allied species, chloranthum, described from Departments Amazonas Cajamarca in Peru, but at lower elevations. Both these species release their pollen tetrads, unique within Amaryllidaceae, have tri-lobed stigmas, Stenomesson.

During preparation of a treatment Persea for the Flora Mesoamericana three new species were recognized. A description these (Persea albiramea van der Werff, P. brevipetiolata and laevifolia Werff) is presented, as well key to all known in region including brief notes giving synonyms, distribution, noteworthy features species.
Abstract— We studied leaf cuticles of 48 species Beilschmiedia, Endiandra, Potameia, Sinopora, and Syndiclis from eastern Asia Madagascar using light microscopy scanning electron microscopy. This study shows that Lauraceae possess characters useful in taxonomy, including the ornamentation periclinal walls, straightness uniformity thickness anticlinal stomatal ledges, surface complex. The ledges complex are valuable supraspecific grouping while presence/absence round oil deposits applicable...
species recently separated from Licaha and reinstated on its own, is included here in Mezilaurus.Eight species, Mezilaurus
We report on the cuticular features of a number Lauraceae species belonging to genera Aspidostemon, Beilschmiedia, Cryptocarya and Potameia , all from Madagascar. The goal this project was ascertain if could be used determine generic placement poorly known previously placed in Aspidostemon several specimens which combine characters Beilschmiedia . conclude that define groups or these are promising tool solving possess typical more than one genus.
A synoptic treatment of the Tachigali Aubl., including Sclerolobium Vogel, in northern South America (Colombia, Venezuela, Guyana, French Guiana, Suriname, Amazonian Brazil, Ecuador, and Peru) is presented contains brief descriptions of, a key to, 54 species recognized America. Ten species, T. barnebyi van der Werff, bicornuta candelabrum cenepensis chrysaloides ferruginea fusca inconspicua loretensis vaupesiana are newly described. Three overlooked names published by Tulasne (T. glauca,...
