You’ll Never Guess What ‘Orchid’ Means (Hint: It’s Naughty)

At first blush, orchids seem dainty.    We adore their sweet scents, exquisite flowers, and even delicate taste, in the case of Vanilla‘s seed pods.

Few people know the real meaning of the word ‘orchid’: TESTICLE.

Yes, you read that right.   Vanilla is anything but vanilla.

Orchids
Clockwise from top: testicle, testicle, testicle, testicle, testicle

This is not some obscure plant family with a dirty name.  Orchids are literally ~28,000 species, 10% of the world’s seed plants.  And they’re named after gonads.

But why?  In order to find an orchid’s namesake, you’ll need to look where the sun don’t shine.

These evocative lumps are tubers that serve an adaptive purpose.  Many orchids live on tree branches or in other dry environments where they don’t have easy access to water and nutrients year-round.

When parts of an orchid seasonally die back, the orchid stores its carbohydrates in two starchy tubers to sustain itself until the next wet season.  The result is basically a pornographic potato.  Humans can eat orchid tubers as a starchy snack; they’re called chikanda in Zambia.

So how did such a naughty name become official?  It turns out that the name has a long, hard history.   The Latin word for orchid was orchis, which comes from the Greek orkhis, meaning “testicle”.

The Greeks weren’t the only ones to have dirty thoughts about monocots.  In Middle English, orchids were called “ballockwort”.

When a French botanist, Antoine Laurent de Jussieu, coined the official family name  Orchidaceae in 1789, he based it on the Latin.  And when John Lindley published School Botany in 1845, he shortened Orchidaceae to “orchid”.

Humans aren’t even the only ones to think that orchids look a little naughty.  Some orchids trick bees into pollinating them by looking like an attractive mate.

Ophrys sphegodes flowers have fake “wings” and “antennae”, and emit chemicals that mimic the sex pheromones of female bees.

Male bees attempt to copulate with the flowers, not knowing that they’re being duped by a plant.  As the bees go from flower to flower trying to get laid, O. sphegodes‘ pollen spreads.  This process is literally called “pollination by sexual deception”.

The same strategy is used by other tricky testicles against many of the world’s insects.

For example, the orchid Chiloglottis trapeziformis attracts wasps with pheromones…

… and Lepanthes glicensteinii tricks the heck out of fungus gnats.

So the next time you’re at a botanical garden or visiting your grandma, you should announce that orchids are deceptive testicles spread by horny insects.   Everyone will thank you for your knowledge of ~plant anatomy~!
