A plant that was last seen in the forests of Sarawak a century and a half is lost no more. Ladies and gentlemen (drumroll please!) here comes the “fairy lantern”!

The plant Thismia neptunis has been dubbed as such thanks to its extravagantly rococo-style flower, which makes it resemble a flamboyant lantern or else a praying mantis, if you will. The flower was discovered for science in 1866 by Odoardo Beccari, an Italian botanist who went on an expedition in the jungles of Borneo and Sumatra.

In the Malaysian part of Borneo Beccari came across a curious-looking plant. The plant, which boasted a weird-looking flower, had no leaves and contained no chlorophyll, which means it didn’t perform photosynthesis and thus needed no sunlight to survive. More curiously still, it turned out to live underground where it subsisted on fungi parasitically.

“Thismia neptunis is what’s called a ‘mycoheterotroph,’ meaning it’s part of a group of plant species that has given up photosynthesis entirely, in favor of living as parasites,” LiveScience explains. “They grow no functional leaves and do most of the work they need to survive underground. T. neptunis is most easily identified by its sexual organ: a small, 3.5-inch (9 centimeters) flower it pokes out of the ground, that looks like it might belong on an alien planet or perhaps deep in the ocean.”

So there you have it.

Beccari was an accomplished illustrator and penciled intricate drawings of the plant. But then no one saw the “fairy lantern” until last year when a Czech team of researchers rediscovered in the same area of Sarawak where the Italian botanist himself saw it. That area, they explain in a paper they wrote on their (re)discovery, is at the Gunung Matang massif in western Sarawak.

The plant has a smooth off-white stem attached to a simple system of roots through which the plant sucks nutrients from underground fungi. “Its bulb has the shape of a bruised and swollen thumb — only it is sickly pale, striped with red, and has an opening at the tip like the mouth of a sea-worm,” LiveScience notes. “The most dramatic part of the flower is the trio of “red, hairy” appendages sticking straight up like a shrimp’s long antennae from flat protrusions around the bulb — part of its pollen-producing organ.”

It’s as yet not known how far and wide the plant ranges in the area, but the plant is definitely rare. It can be detected only during its short annual flowering when it pokes part of itself out of the ground so that it can be pollinated by insects through its weirdly shaped flower. There are 76 species of “fairy lanterns” currently known to belong to the plant’s genus and of those 30 have been discovered since 2011.
