…I wasn’t able to find out if Wasabia and Armoracia are much related, though I doubt it.
No doubt I gave up too easily, something else I probably wouldn’t do now, like alliterate post titles and neglect to search for ex situ holdings. Anyway, the paper Toward a Global Phylogeny of the Brassicaceae ((Mol. Biol. Evol. (2006) 23 (11): 2142-2160. doi: 10.1093/molbev/msl087)), which came out a few months before that 2006 blog post on mine on wasabi which I have been revisiting, clearly relegates Eutrema (aka Wasabia) and Armoracia to quite distinct clades of the Brassicaceae (click on the phylogenetic diagram to see for yourself). Thanks to Ruaraidh for tracking that down. Not least because it gives me a chance to also link to yesterday’s post at The Botanist in the Kitchen on the phylogenetic tree of food plants in general, and nevermind that it doesn’t seem to feature wasabi.
