  • What's that awful smell? Cat urine? Semen? Rancid butter? Possibly one of these gorgeous city trees?

    Speaking of terrible smelling plants... My mother did some massive gardenwork a few years ago and, like the good child that I am, I helped with some of the upkeep after everything was planted. One of those plants, when crushed or cut, was uniquely and overwhelmingly unpleasant to smell.
    I looked up what it was out of curiosity and was surprised to find it was Elderberry. That Monty Python insult makes so much more sense now.

      Draconic74 For the record, I'm not trying to say you're wrong here. However, when I asked what "smelled of elderberries" meant, my own mother told me that it means he's addicted to (presumably elderberry) wine - he's a drunkard. This has always sounded like an excellent explanation to me, as well as an effectively rude insult. As someone who's smelled elderberries before, would that make any sense?

    On day when I was a child, my sister and I saw a Pyrus Calleryana tree in Washington DC and because the flowers were so pretty, we decided to take one of the branches off and bring them home for our mom! For a few days, we couldn't figure out what that disgusting fishy smell was in our house! Our kitchen, since we put the branch in a vase next to our refrigerator, smelled terrible and it was so funny when we found that it was the beautiful and innocent looking flower branch! So I started smiling and laughing when I saw you brought it up in this video! 😂

    Ginkgo's are very interesting. What amazes me particularly, since I know Japanese, is the origin of the name. The tree comes from China originally, where it is called 白果 (bái guǒ), meaning white fruit - or in older times 銀果 (yínguǒ) meaning silver fruit, or else 銀杏 (yínxìng), meaning silver apricot. This last word (or rather it's middle Chinese equivalent) was what was borrowed by the Japanese, and is now pronounced as "ginnan" in modern Japanese.
    From 銀杏 (ginnan), we get the English name, but the change is really strange. in 1690, a German naturalist by the name of Engelbert Kaempfer was able to visit Japan (at a time when the country was otherwise closed to foreigners, remarkably). He recorded the name of the ginnan plant, and even brought seeds back to Europe. However, he seems to have misread the name of the plant, or else used an uncommon variant of the name, because the second character 杏 can also be read as "kyō."
    Japanese Kanji, unlike their Chinese counterparts, often have many different readings. They have readings based on Chinese loanwords, or meanings based on native Japanese words, or a variety of both. In this case, both these readings are ultimately from Chinese, but from words borrowed at different periods and different dialects.
    But more crazy than that error, we have the "kgo" spelling, which as far as anyone can tell, was just a mistake spelling. Had he written it correctly (using the Romanization style he had employed), it would have been kio or kjo.
    And then finally, we have the fact that everyone pronounces the word "ginkgo" as "gingko." The history of the word is just one mistake after another.

      Gotta be honest here I do not know near enough about Asian languages to understand exactly what happened besides the apparent mistranslation of kjo/kio to kgo. So I don’t think I can fault the guy for not being the best at Japanese in 1590. But hey just the attempt at trying to translate the Japanese name to English is a little admirable. Most distant cultures would be like “alright well that name is stupid as hell plus I can’t say it, we’re gonna call it the green fan tree” lol

    • @rdreher7380
      @rdreher7380 Před rokem

      @@monhi64 Yeah, understanding the complexities of Japanese and its kanji is very hard, though very rewarding. I tried to summarize it briefly, which can end up rather dense. Let me put it another way:
      When the Japanese borrowed the Chinese writing system, they first used it to simply write Chinese, like the way Latin was used throughout Europe in the middle ages. However, they were not reading and writing in modern Mandarin; at first they were writing in a very old dialect of Wu Chinese, which is very different. This was in the 5th and 6th century.
      Later on the Japanese began using and borrowing a different type of Chinese, "middle Chinese," an old type of Mandarin. This type of Chinese mostly overtook the old Wu-based type that Japan was using before, starting in the 7th century.
      But then the layers keep getting lathered on. Japanese never stopped borrowing words from Chinese. Even to this day there are words borrowed from modern Mandarin. Chinese continued to change, but the Chinese characters remained standard, so as Japanese borrowed new words, it sometimes borrowed new ways to read the same character.
      The Character that is important to this story is 杏, which means "apricot." When the Japanese borrowed it from Wu Chinese, it was pronounced something like "gyao" which later became just "gyō." When they borrowed the same word from Middle Chinese, it was "kao" which changed to "kō." However, the word for the fruit of the ginkgo tree: 銀杏 was borrowed even later, in the 12th century, and became the word "ginnan" in Japanese.
      So now 杏 can be read as gyō or kō or an, but oddly enough it seems that the 杏 in 銀杏 gained yet another way of reading it: "ginkyō." This likely comes from reading the character 杏 as "gyō" (the oldest reading), but applying the typical sound rules of Japanese. In Japanese, /g/ usually doesn't follow a /N/ sound, while /k/ can, so you get gingyō becoming ginkyō. Or else, this reading might have been a mix of gyō and kō, it's hard to say exactly where it came from, but it became the most typical reading for the character.
      Thus if you were a mostly literate Japanese person sometime in the Edo period, but were not familiar with the name of the fruit of ginkgo, and thus knew it used a more unusual reading of 杏 as "an," it would be a reasonable guess to think it is the more usual "kyō" reading.
      Engelbert Kaempfer was German, not English, so for him Y is not a typical letter. Instead he would have written the Y-sound as either or (like in German), so it's likely he meant to write the word 銀杏 as "ginkio" or "ginkjo." However, perhaps his notes were misread or something, and this became "ginkgo" instead.
      The funniest part is, you might notice I said that "ginnan" or "ginkyō" is the "fruit" of the ginkgo tree. In Japanese, the tree itself is not called either of these words, but rather "ichō." This too came from a Middle Chinese word, the name of the ginkgo tree itself. Again Kaempfer was likely confused or mistaken, thinking the name of the tree was "ginkyō" when that was rather then name of its fruit!

      加藤みずっち Simple. If you're trying to get someone to understand something, you use something they have a point of reference for. If I'd never smelled semen but had smelled those plants, your statement would make more sense. But considering semen is a fairly common substance that I'd guess a majority of people have interacted with, it's a better base descriptor than the other way around.

    In the field behind my house, there's a little patch of woods that's slowly being overtaken by Callery Pear trees. Its kind of fascinating to watch it happen as the seasons go by. My old highschool planted 2 a few years ago and now there's like 10. And they grow on the sides of highways and grow into power lines and stuff. When they call it an invasive species they aren't kidding.

    I once did an experiment where I presented Bradford pear (Callery pear) flowers to a group of people and asked each of them to take a whiff. A few people said they didn't smell anything, a few said the flowers smelled mildly unpleasant, and a few visibly cringed upon sniffing the flowers and reported that the smell was extremely unpleasant. My sample size was pretty small (about 6-8 people), but it suggests that some people might not be able to smell the smell of Bradford pears. (Unfortunately I didn't control for whether or not anyone had a stuffy nose, so better testing is needed)

    Callery Pears(aka Bradford Pears) are amazing, y'all. As mentioned here, they smell very much like spooge. The pears are laughably tiny, astringent things that are great for birds (their intended target, of course!), but inedible for humans.
    Best of all, though, is what they do once they grow big enough. Because they tend to have low-set trunk crotches, they also tend to split in half when subjected to high winds. My aunt and uncle got to enjoy dealing with both Callery Pears next to their house crashing onto different parts of the house over a period of 5 years.

      These smelly tree are hardy, they don't require a lot of care to look nice so they're chosen by city planning because they would require less overall time+money maintaining them. Plus, they only smell seasonally, and you usually have to get pretty close to them (unless there's a lot of them, or you're downwind) to actually smell them.

Almost everyone had gotten used to the smell and children (like me) used to pick the flowers and just hold a bunch of them. Kids from outside the neighborhood hated it. But to me it's the smell of childhood springtime. And it would often get combined with the smell of linden trees and lilacs.

    I've often noticed that trees with catkins smelled of rancid semen. In the UK there are still a lot of chestnut woodlands--though few trees have decent sized nuts (I think that some trees join the fruit clusters together in 4s, to make room for the good sized nuts). As I used to help record fungi year round, I was often in these woods when the chestnut trees were flowering, and was amazed at the awful headachingly powerful fumes from the catkins! Stinkhorn fungi are pleasant in comparison!

    I always wondered where the semen smell was coming from when I exited the front doors of the YMCA into the parking lot; I noticed it only happened during a particular time of year, but didn't relate it to the seasons, and although I thought it was coming from the trees, I thought I must be wrong/crazy...now I know! It's such an awful smell.

    Black Walnut! There was a small area (about 5 suburban lots) that wasn't deforested despite the rest of the surrounding land being farmland or developed. It was about 50% oak and 30% black walnut with a few poplar and mulberry. Every year when those walnuts dropped, our neighborhood smelled like roadkill covered in regurgitated sauerkraut.
    Last year when the new owner of the property decided it was too much of a fire hazard, he thinned it out considerably and the walnut trees were targeted with extreme prejudice.

    There's a flowering plant where I live that smells like a shirt that's been used at the gym too many times but only when it, the plant, is in bloom. I was standing at a crosswalk once, waiting for the light and I smelled this smell and turned and saw what I expected to be a homeless man but it was just some office drone waiting to cross the same direction. It took smelling the smell again and seeing the same plant in bloom to make the connection. Science has some unexpected twists sometimes.

    We had a few Callery Pears in front of my old school and I can confirm that they smell like dead fish. The semen part I'm not too sure about. It doesn't smell like any semen I've ever smelled. But that dead fish part is completely accurate. I'd have to walk past them a couple of times a day and I always remember thinking that those trees shouldn't exist because natural selection should've taken their genes out of the pool. Who knew bees liked fish?

They have kind of cracked looking bark, and i see the trunks painted white around town. In the spring, the white flowers smell sooo bad. There are about 4 giant ones in a row at my school, and I think it's funny to watch all the girls walk by them and gag

    Mmm lovely ginko fruits. TONS of those trees in the California bay area. The fruit smells like someone took a hot dump then glazed it in doughnut glaze. But the smell is really only the fruit and only lasts until someone comes and cleans them up. In some towns people are avid foragers and pick all the fruit before it falls (You can eat a small amount of the seeds as a treat, but too many is poisonous).

    Interesting fact:
    The earliest use of the term "aromatic" was in an article by August Wilhelm Hofmann in 1855.[1] Hofmann used the term for a class of benzene compounds, many of which have odors (aromas), unlike pure saturated hydrocarbons. Aromaticity as a chemical property bears no general relationship with the olfactory properties of such compounds (how they smell), although in 1855, before the structure of benzene or organic compounds was understood, chemists like Hofmann were beginning to understand that odiferous molecules from plants, such as terpenes, had chemical properties that we recognize today are similar to unsaturated petroleum hydrocarbons like benzene.
