Pollination biology of a Chloraeinae orchid
The pollination biology of very few Chloraeinae orchids has been studied to date, and little is known about pollinator behaviour. Sanguinetti et al. study the floral features, breeding system and pollinator behaviour in...

Floral characters in Capanemia
Capanemia, an orchid comprising seven species and mostly found in the Brazilian Atlantic rain forest, is divided into two sections based on leaf shape. Buzatto et al. examine floral morphology and anatomy and conclude...
Vanda Miss Joaquim
A.J. Cann: I posted here recently about my orchid addiction, and Vanda is one of my favourite genera, so it was fascinating to read the history of a beautiful cross, Vanda Miss Joaquim, originally made in 1893, brought...
The Eric Young Orchid Foundation
In recent years (since I got the bug), my holidays have included orchid-hunting as a compulsory element! On a recent visit to Jersey, I came unstuck as by the end of a rather dry July, the wild orchid season on the...
Phylogeographic patterns of Epipactis lineages
Phylogeographic patterns of <i>Epipactis</i> lineages Epipactis is a widespread orchid genus encompassing morphologically and genetically problematic aggregates of taxa, such as the E. helleborine species...
An orchid that persuades wasps to date outside their species
Margaret Moran at My Growing Passion has put up a photo of Cryptostylis subulata the Large Tongue Orchid that she has growing in her garden. Her post includes an explanation of how it reproduces. It relies on wasps to...

Coexistence of multiple cytotypes of an orchid
Coexistence of multiple cytotypes of an orchid Large-scale cytotype surveys have indicated that intraspecific ploidy diversification is much more common than previously thought. Trávníček et al. examine inter- and...
Orchid reproductive isolation and pollination success
Orchid reproductive isolation and pollination success Few studies have investigated whether non-rewarding plants affect the pollination success of rewarding plants when they grow in close proximity. Sun et al...
Pollen viability in Mediterranean orchids
Pollen viability in Mediterranean orchids Evaluation of pollen viability has generally been confined to a relatively low number of species. Bellusci et al. study five related Mediterranean orchid genera (Anacamptis...
Evolution of mycoheterotrophy from mixotrophic ancestors
Evolution of mycoheterotrophy from mixotrophic ancestors Nutritional changes associated with the evolution of achlorophyllous, mycoheterotrophic plants have not been inferred within a robust phylogenetic framework...
