Phylogenetic endemism of the orchids of Megamexico reveals complementary areas for conservation [PDF]

Plant Diversity, 2022
Orchid diversity provides a unique opportunity to further our understanding of biotic and abiotic factors linked to patterns of richness, endemism, and phylogenetic endemism in many regions. However, orchid diversity is consistently threatened by illegal

From flower to fruit: The origin of the trilocular ovary and fruit development in Phragmipedium longifolium (Warsz. & Rchb.f.) Rolfe (Orchidaceae: Cypripedioideae). [PDF]

Plant Biol (Stuttg)
Phragmipedium longifolium has a trilocular ovary with a post‐genital septum, and during fruit development, lignification plays a crucial role in facilitating dehiscence and seed dispersal. Abstract While carpels in Orchidaceae are predominantly unilocular, trilocular carpels can also occur, mainly in branches separated during the early diversification ...

Recent origin and rapid speciation of Neotropical orchids in the world's richest plant biodiversity hotspot. [PDF]

New Phytol, 2017
Summary The Andean mountains of South America are the most species‐rich biodiversity hotspot worldwide with c. 15% of the world's plant species, in only 1% of the world's land surface. Orchids are a key element of the Andean flora, and one of the most prominent components of the Neotropical epiphyte diversity, yet very little is known about their ...

Complete chloroplast genome of Oncidium Gower Ramsey and evaluation of molecular markers for identification and breeding in Oncidiinae [PDF]

BMC Plant Biology, 2010
Background Oncidium spp. produce commercially important orchid cut flowers. However, they are amenable to intergeneric and inter-specific crossing making phylogenetic identification very difficult.

Oncidiinae (Orchidaceae) on the great curve of the Xingu River, Pará state, Brazil [PDF]

Brazilian Journal of Biology, 2015
Among the studies on Orchidaceae in the Amazon, none comprised the region of the Great Curve of the Xingu River, located in the lower Xingu river. The aim of this study was to inventory and taxonomically study the species of Oncidiinae (Orchidaceae) in ...

Morphological and genetic evidence support the reinstatement of the long-forgotten Telipogon teuscheri (Orchidaceae, Oncidiinae) from southwestern Ecuador [PDF]

PhytoKeys
Telipogon teuscheri, a rare orchid species from southwestern Ecuador, was described by Garay in 1958, but has long been forgotten after being placed in synonymy with T. tesselatus by Dodson in 1989.
