10 Fascinating Facts About Corpse Flowers

Big, smelly, rare, phallic—these adjectives all describe Amorphophallus titanum, commonly known as the corpse flower. While native to western Indonesia, the plant is currently taking Washington, D.C. by smelly storm: The last of three—count 'em, three—corpse flowers to bloom this summer began its stinky blossoming this week at the United States Botanic Garden. In honor of the occasion, here's some trivia to celebrate one of nature's stinkiest plants.

1. THE CORPSE FLOWER'S LATIN NAME IS NSFW (OR BRITISH TV).

No, it's not just you: Amorphophallus titanum really does look like a large, lumpy penis. In fact, the plant gets its scientific name from three roots: amorphos (without form), phallos (penis), and titanum (giant).

Can't say the plant's Latin name in polite company without blushing? Thanks to David Attenborough, the English naturalist and TV personality, you can also opt to use its common name, Titan arum. While narrating BBC nature documentary series "The Private Life of Plants," Attenborough thought the corpse flower's proper name was too improper to say on TV, so he coined a less-scandalous moniker. Or, you could simply go with its Indonesian name, bunga bangkai.

2. A 19TH-CENTURY ITALIAN BOTANIST 'DISCOVERED' THE CORPSE FLOWER.

Western scientists first learned of Amorphophallus titanum in 1878, when Italian botanist Odoardo Beccari came across the enormous plant growing in the rainforests of Sumatra, a large island in western Indonesia. The specimen he recorded had a circumference of around 5 feet, and its height was around 10 feet.

Beccari tried to ship the flowering shrub's corms, or giant underground tubers, back to Europe, but French customs ended up holding them under an order designed to prevent the spread of the grapevine pest Phylloxera. Still, a few seeds survived against the odds, and a single seedling was sent to the Kew Botanic Gardens in England, where Beccari had once studied. There, it flowered in 1889. In 1926, when the same corpse flower bloomed again, the crowds were so large that police were brought in to control them.

3. THE CORPSE FLOWER GROSSED OUT THE ENGLISH (IN MORE WAYS THAN ONE).

Not surprisingly, the corpse flower quickly gained notoriety in Europe: An English artist hired to illustrate the plant is said to have become ill from the odor, and governesses forbade young ladies from looking at it, for obvious reasons.

4. A CORPSE FLOWER ISN'T REALLY A SINGLE FLOWER.

Technically, a corpse flower isn't a single flower; it's a flowering plant with clusters of blooms. The plant consists of a thick central spike, known as a spadix, with a base that's encircled by two rings of "male" and "female" flowers. A large, frilly leaf called a spathe envelops these flowers to protect them.

5. CORPSE FLOWERS ARE, AS THEIR LATIN NAME SUGGESTS, ENORMOUS.

Aside from its smell, a corpse flower's most noticeable quality is its sheer size. The plant holds the record for the world's largest unbranched inflorescence (a fancy term for describing a floral structure made of many smaller individual flowers), and it can reach heights of up to 12 feet in the wild. Cultivated corpse flowers are smaller, measuring anywhere from 6 to 8 feet.

6. THEY DON'T HAVE AN ANNUAL BLOOMING CYCLE.

Years, or even decades, can pass before a corpse flower reaches peak bloom. As the big moment finally approaches, the plant's bud grows several inches per day before slowing down its growth. Two protective leaves, called bracts, shrivel and fall off the spathe's base. Then, the spathe unfurls over roughly 24 to 36 hours, giving curious onlookers just a small window to see (and smell) its maroon-colored insides for themselves.

7. THERE'S SCIENCE BEHIND THE CORPSE FLOWER'S TERRIBLE SMELL.

When a corpse flower blooms, the spadix heats up to temperatures of up to 98°F as the plant unleashes a stench akin to rotting flesh. "Those pulses of heat cause the air to rise, like a chimney effect," Ray Mims, a spokesperson for the U.S. Botanic Garden, explained to Washingtonian magazine. "It gets the stench up in the air" to attract pollinating dung beetles and carrion beetles, who are drawn to the scent of rotting flesh.

Experts have identified different molecules responsible for titan arum's stink, including dimethyl trisulfide (like limburger cheese), trimethylamine (rotting fish), and isovaleric acid (sweaty socks).

8. CORPSE FLOWERS GROW FRUIT WHEN THEY'RE POLLINATED.

Once a corpse flower finishes blooming, it doesn't die. The spathe withers and collapses after a few days, and if pollinated, the plant soon produces hundreds of small, golden-colored fruits. These berry-like seeds are eaten and dispersed by animals such as birds and the rhinoceros hornbill, or harvested in captivity by garden conservation scientists. (No word on how they taste, as they're reportedly not suitable for human consumption.)

Once the seeds ripen from gold to dark orange, and then to dark red—a stage that lasts for five or six months—the corpse flower goes dormant. Then, it sprouts as a tree-like leaf during its next few life cycles as it stores away energy from the sun. Each cycle, the leaf grows bigger and bigger, before dying. Once the plant's corm is fully replenished, it finally blooms again.

9. THE CORPSE FLOWER WAS ONCE THE BRONX'S OFFICIAL FLOWER.

In 1937, the New York Botanical Garden became the proud home of America's first recorded corpse flower bloom. Two years later, yet another flower bloomed in the Bronx garden. Borough president James J. Lyons was so tickled, he designated Amorphophallus titanum as the Bronx's official flower. ''Its tremendous size shall be symbolic of the fastest-growing borough in the City of New York,'' Lyons said, according to The New York Times. Meanwhile, news crews covering the event are said to have nearly fainted from the smell.

The Bronx used the corpse flower as a symbol until 2000, when then-borough president Fernando Ferrer, aiming to overhaul the municipality's image, changed its official flower to the day lily. "I hate to think of the corpse flower as the Bronx flower, because people would think the Bronx and think, 'The Bronx stinks,'" Michael Ruggiero, then senior curator for horticulture at the New York Botanical Garden, told the Times. "The Bronx is a people place, and the corpse flower is not a people plant. The day lily is, and therefore is a good fit for the Bronx."

10. THE CORPSE FLOWER IS THREATENED BY HABITAT LOSS.

Corpse flowers aren't just rare—they're also vulnerable to habitat loss and destruction, as vast swaths of Sumatra's rainforests are chopped down for timber and to clear ground for oil palm plantations. According to one estimate provided by the Kew Royal Botanic Gardens, Indonesia has now lost around 72 percent of its original rainforest cover. This contributes to the flower's demise, and also threatens important pollinators like the rhinoceros hornbill.

Here’s What You Need to Know About the New Coronavirus

This morning, the Centers for Disease Control and Prevention (CDC) confirmed the second case of the recently discovered coronavirus in the U.S. Find out what it is, where it is, how to avoid it, and all the other need-to-know information about the illness below.

What is the new coronavirus?

Coronaviruses are a group of viruses named for the crown-shaped spikes that cover their surfaces (corona is the Latin word for crown). According to the CDC, human coronaviruses can cause upper-respiratory tract illnesses, including the common cold, and can sometimes lead to more severe lower-respiratory tract issues like pneumonia or bronchitis.

Because this latest coronavirus, 2019-nCoV, is so new, health officials are currently trying to figure out how it works and how to treat it. It’s not the first time a potent new coronavirus has caused an international outbreak: SARS-CoV originated in Asia and spread to more than two dozen countries in 2003, and MERS-CoV first infected people in Saudi Arabia before spreading across the globe in 2012.

Where is the coronavirus outbreak happening?

The majority of cases are in China, which counts more than 800 confirmed diagnoses. Most are in Wuhan, a city in China’s Hubei province where 2019-nCoV was first detected last month. Additional cases have been reported in South Korea, Japan, Singapore, Hong Kong, Macao, Taiwan, Thailand, and Vietnam.

The CDC has confirmed two U.S. cases—a man in his thirties outside Seattle, and a 60-year-old woman in Chicago—both of whom had recently returned from trips to Wuhan. A CDC official said another 63 potential cases are being investigated in 22 states, and airports in New York, Chicago, Los Angeles, Atlanta, and San Francisco are conducting health screenings on passengers arriving from China.

Chinese officials have shut down transportation to and from Wuhan. Tourist spots like Beijing’s Forbidden City, Shanghai Disneyland, and a portion of the Great Wall are also closed temporarily.

What are the symptoms of the new coronavirus?

Symptoms are similar to those caused by a cold or the flu, including fever, dry cough, and breathing difficulty. The New York Times reported that as of Friday morning, 25 people in China have died from the virus, and most of them were older men with preexisting health conditions like cirrhosis, diabetes, and Parkinson’s disease.

How does the new coronavirus spread?

Because most of the early cases of 2019-nCoV were traced back to a seafood and meat market in Wuhan, health officials think the virus originally spread from infected animals to humans, but it’s now being transmitted from person to person.

Though scientists are still studying exactly how that happens, the leading theory is that it travels in tiny droplets of fluid from the respiratory tract when a person coughs or sneezes.

How do you avoid the new coronavirus?

The CDC is warning everyone to avoid any nonessential trips to Wuhan, and to avoid animals or sick people if you’re traveling elsewhere in China. If you’ve been to China in the last two weeks and experience any of the symptoms listed above, you should seek medical attention immediately—and you should call the doctor’s office or emergency room beforehand to let them know you’re coming.

Otherwise, simply stick to the precautions you’d normally take when trying to stay healthy: Wash your hands often with soap and water, cover your nose and mouth when coughing or sneezing, stay away from sick people, and thoroughly cook any meat or eggs before eating them.

Should you be worried about the new coronavirus?

The global health community is taking 2019-nCoV seriously in order to curb the outbreak as quickly as possible, but you shouldn’t panic. The CDC maintains that it’s a low-risk situation in the U.S., and public health officials are echoing that message.

“We don’t want the American public to be worried about this, because their risk is low,” Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, told USA Today.

Has An Element Ever Been Removed From the Periodic Table?

Barry Gehm:

Yes, didymium, or Di. It was discovered by Carl Mosander in 1841, and he named it didymium from the Greek word didymos, meaning twin, because it was almost identical to lanthanum in its properties. In 1879, a French chemist showed that Mosander’s didymium contained samarium as well as an unknown element. In 1885, Carl von Weisbach showed that the unknown element was actually two elements, which he isolated and named praseodidymium and neodidymium (although the di syllable was soon dropped). Ironically, the twin turned out to be twins.

The term didymium filter is still used to refer to welding glasses colored with a mixture of neodymium and praseodymium oxides.

One might cite as other examples various claims to have created/discovered synthetic elements. Probably the best example of this would be masurium (element 43), which a team of German chemists claimed to have discovered in columbium (now known as niobium) ore in 1925. The claim was controversial and other workers could not replicate it, but some literature from the period does list it among the elements.

In 1936, Emilio Segrè and Carlo Perrier isolated element 43 from molybdenum foil that had been used in a cyclotron; they named it technetium. Even the longest-lived isotopes of technetium have a short half-life by geological standards (millions of years) and it has only ever been found naturally in minute traces as a product of spontaneous uranium fission. For this reason, the original claim of discovery (as masurium) is almost universally regarded as erroneous.

As far as I know, in none of these cases with synthetic elements has anyone actually produced a quantity of the element that one could see and weigh that later turned out not to be an element, in contrast to the case with didymium. (In the case of masurium, for instance, the only evidence of its existence was a faint x-ray signal at a specific wavelength.)
