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.

Indeed, thanks.

This takes the citrus gram into 3D

A Persian lime is a cross between a Key lime and a lemon? I never would have guessed that, that's really interesting.

Yeah makes sense though. And for those reading Persian lime is the regular lime found in US grocery stores. Kaffir lime (one of the cornerstone species not included on the ternary axes) is the lime used in Thai food

From what I can tell, the papeda is included as a sort of addendum in the bottom right corner of the chart.

You might need several more dimensions (assuming this quoted claim is correct - it does come with a Citation Needed)

> Recent genetic analysis shows the papedas to be distributed among distinct branches of the Citrus phylogenetic tree, and hence Swingle's proposed subgenus is polyphyletic and not a valid taxonomic grouping, but the term persists as a common name.

Good point, as ever.

So what would be interesting is an interdimensional citrus fruit.

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.

There are lots of citruses missing; the ones in the chart are only the ones I could find reliable values for (from the sources at the bottom). I'll add more if I can find other reliable sources. For what it's worth, I think the etrog is basically a pure citron variety. Yeah, that's definitely an issue. If I get a chance, I'll curate images to add!

Fascinating. Look forward to your update.
