Indigo in the Americas

I knew a bit about indigo — but not that in addition to the Old World’s Indigofera tinctoria there’s a separate species in the same genus that was used in ancient America for making dye. I found out because of some interesting detective work on the Maya pigment. I figured that the indigo plant mentioned in the research was something completely different, but it turns out to be I. suffruticosa. Although there do seem to be other genera that produce the colour.

Weekly helping of potatoes

The Economist seems to have a thing about potatoes this week. There’s a story about how Peru is trying to cash in on its spud heritage. (Note to editor: the olluco is not a type of potato.) There’s a book review, of John Reader’s Propitious Esculent. And there’s even an editorial explaining how the humble tuber is at the root — as it were — of globalization. The International Year of the Potato cannot be over too quickly.
