Taxonomic revision of the native Magnolia (Magnoliaceae) species of Brazil.
The genus (Magnoliaceae) has a wide and disjunct geographic distribution ranging from Eastern and South Asia to Malaysia, extending across the Neartics and reaching into the Neotropics. Regarding its infrageneric classification, the genus is divided into three subgenera: , and , the latter including the section Talauma in which the... -

Trials and tribulations of Neotropical plant taxonomy: Pace of tree species description.
Dada la inédita preocupación por la actual pérdida global de biodiversidad, resulta importante identificar las mejores estrategias para describir nuevas especies de manera más eficiente, completar el inventario de la flora Neotropical e implementar a tiempo estrategias de conservación apropiadas. Este estudio pretende responder la pregunta de cuánto tiempo... -

Repeated evolution of pollination syndromes in a highly diverse bromeliad lineage is correlated with shifts in life form and habitat.
Mutualistic plant-pollinator interactions play a critical role in the diversification of flowering plants. The spatiotemporal correlates of such interactions can be understood in a phylogenetic context. Here, we generate ddRAD-seq data for the highly diverse Vriesea-Stigmatodon lineage to test for correlated trait evolution among pollination syndromes and life form, habitat... -

Clusia chuj (Clusiaceae), a new tree species from the border between Guatemala and Mexico.
(Clusiaceae) is described and illustrated. This new taxon differs from the other species of the genus by being a tree up to 15 m tall with many-flowered inflorescences. The non-resiniferous, quadrangular flowers have thick, pale-yellow petals, and the androecium in the staminate flowers have 20 (– 30) free, short stamens....Luján, Manuel

Diversification dynamics in the Neotropics through time, clades, and biogeographic regions.
The origins and evolution of the outstanding Neotropical biodiversity are a matter of intense debate. A comprehensive understanding is hindered by the lack of deep-time comparative data across wide phylogenetic and ecological contexts. Here, we quantify the prevailing diversification trajectories and drivers of Neotropical diversification in a sample of 150... -

Clusia falcata (Clusiaceae), an endangered species with exceptionally narrow leaves endemic to Chiapas, Mexico.
(Clusiaceae), a new species from Chiapas, Mexico, is described and illustrated. This new taxon is distinctive for its leaves, among the narrowest of all known species, having lanceolate to oblong laminas that are mostly 10 – 15 × 2 – 2.5 cm. The flowers have a quadrangular perianth with succulent...Luján, Manuel ; Cacho, N. Ivalú ; Pérez-Farrera, Miguel Ángel ; Hammel, Barry

Morphoanatomical and phylogenetic characterization of the ectomycorrhiza between Laccaria squarrosa with Pinus pseudostrobus and its relevance for reforestation programs.
Background: Pinus (Coniferophyta) and Laccaria (Basidiomycota) establish ectomycorrhizal symbioses in natural forests. However, their detailed morphoanatomical and phylogenetic characterization have received little attention. Accurate identification of native host symbionts is of paramount relevance to the production of mycorrhized seedlings for successful reforestation programs. Questions/Objective: We aimed to determine if L....Herrera, Mariana ; Yu, Fu-Qiang ; Ramos-Rendón, David ; Martínez-Reyes, Magdalena ; Hernández-Santiago, Faustino …

Evolutionary history of CAM photosynthesis in Neotropical Clusia : insights from genomics, anatomy, physiology and climate.
Clusia is a remarkable genus of Neotropical woody plants as its members engage in either C3 photosynthesis or employ, to varying degrees, crassulacean acid metabolism (CAM) photosynthesis. Information about the evolutionary history of CAM in Clusia is scarce. Restriction site-associated sequencing of 64 species (20% of the genus) provided strong... -

Hybridization: a ‘double-edged sword’ for Neotropical plant diversity.
Hybridization can facilitate both evolutionary diversification and extinction and has had a critical role in plant evolution, with c. 25% of species known to hybridize in some temperate floras. However, in the species-rich Neotropical flora, the role of hybridization in the evolution of diversity remains unclear. Our review examines studies...Schley, Rowan J ; Twyford, Alex D ; Pennington, R Toby

Two new species of Poecilanthe (Leguminosae: Papilionoideae: Brongniartieae) from Bolivia and Brazil
Two new legume species, Poecilanthe goiasana G.P.Lewis from Brazil and Poecilanthe boliviana G.P.Lewis from Bolivia, are described and illustrated. Previously seven species of the genus were recorded from Brazil, and one from Bolivia. A summary is given of the current circumscription of the papilionoid legume tribe Brongniartieae Hutch., to which...Lewis, Gwilym ; Tebbs, M. ; Wood, J. R. I.

Revision of Guarea (Meliaceae).
The species of Guarea F.Allam. ex L. (Meliaceae) are revised. Sixty-nine species are recognised, a key to the species is provided, all names are typified and descriptions of all species are given. A phylogenetic analysis based on ITS sequence data is discussed. Six new species and one new subspecies are...Pennington, T. D. ; Clarkson, J. J.
