During lockdown I started growing clementine from seed. One of the interesting details of this genus is polyembryonism: multiple seedlings emerging from one seed. Apparently, one of the seedlings will be a clone of the motherplant and the rest will be the product of pollination/genetic reshuffling. My clementine seeds all had 2 seedlings per seed but other attempts (with lemon I think) yielded 3 or more). During my r…

Polyembryony is the reverse of what you think: one embryo is a result of pollination and all the others are clones. The sexual reproduction embryo is often less vigorous and sometimes doesn't develop at all. It makes it easy to reproduce "true" plants, but also makes it difficult to produce hybrids for some species.

Chinotto (apparently called mirtle leaves bitter orange in English?) also has some confused origin (perhaps it's a mutation of some other bitter orange, but it's unclear), and afaict it's not in this chart, or I can't find it.

Citrus fruits are fun.

Seems to be missing the Etrog? https://en.wikipedia.org/wiki/Citrus_taxonomy#Citrons Also, the "click to show search results" is cool but fails for "Arizona Citron" in obvious ways.

I assume the esrog is the primeval citron but I've noticed that Jewish tradition (which rejects the use of hybrid citrons) allows some surprisingly different citrons in practice, popularly associated with Israel, Morocco, Yemen, Corfu etc. These differ considerably in eg rind thickness.

I recently learned about the fact that Sichuan peppercorns are actually related to citrus, so was looking for where the connection is... As it turns out[1], there is a "citrus family" (Rutaceae[2]) and a citrus genus (Citrus[3], in that family). The Sichuan plant is a member of the family, but not the genus (that would be Zanthoxylum[4]). Confusing!

  [3] https://en.wikipedia.org/wiki/Citrus
  [4] https://en.wikipedia.org/wiki/Zanthoxylum
Also, this is a pretty good page on citrus (both family and genus): https://www.clovegarden.com/ingred/citrus.html

Thanks lovely piece of work.

I couldn't find Yuzu, I guess I could have looked at the source JSON file, worked out the co-ordinates that find it on the chart, if its there.

Yuzu seems to be having a bit of a moment, like pistachio nuts.

According to wikipedia they are cultivated from a hybrid of mandarin orange and Ichang papeda, the latter being from another wild lineage than the three shown.
