The Secret of a Plant's Sexual Attraction Is Betrayed by the Shadow of Its Scent

Pollination by sexual deception via pro-pheromone mimicry? nph.onlinelibrary.wiley.com/do

"The #orchid produces chemicals called alkenes, which do not attract the wasps. But these are unusual alkenes... they break down when oxidised into very specific aldehydes... When male #wasps get a whiff of these aldehydes, they go mad with lust & attempt to copulate with the plant."

I've finally managed to photograph my first orchid. As I was walking in the woods, daydreaming as usual, little bright pink dots caught my attention. There were five fairy slipper (Calypso bulbosa) growing on a bed of moss ready to be photographed. This is the first time that I see orchids in a forest. (Vertical photo: open to see in full).

Delicate bright pink orchid next to a pine cone. Around them are moss and twigs.

Drôme-Ragwurz und Fliegen-Ragwurz hybridisieren an Standorten mit gemeinsamen Vorkommen recht leicht. Das Ergebnis ist dann eine hohe, schlanke pflanze mit den Merkmalen beider Elternteile. Hier sind sowohl Fliegen-Ragwurz (links), Drôme-Ragwurz als auch die Hybride (Mitte) zusammen zu sehen.

Orchid's nutrient theft from #fungi sheds light on photosynthesis-parasitism continuum phys.org/news/2025-02-orchid-n paper: onlinelibrary.wiley.com/doi/10

"When the #orchid Oreorchis patens happens to grow close to rotten wood, it shifts its fungal #symbionts to those that decompose the wood and significantly increases the amount of nutrients it takes from them—without ceasing to employ photosynthesis. As a result, the #plants are bigger and produce more #flowers."
