Euphorbia cryptorubra

The paper is out! The paper describing Euphorbia cryptorubra as a new species is officially out. Here is the link to the paper for anyone interested:

I also posted the observation. For now, it is IDed as Euphorbia.

Congratulations! I'll read the paper before confirming the ID.

An interesting and thorough paper, and great illustrations! Thanks for the etymology section, too - I was trying to make sense of "hidden red." Thanks also for the references concerning the recent treatment of the genus Chamaesyce. When I was a baby botanist, they were included within Euphorbia, and now they're back! I'm looking forward to reading up on why.

Thanks for sharing your knowledge with us on iNat.

Thanks! @stevejones , I'm glad you liked it! The main reason Chamaesyce is back in Euphorbia is that it is well nested phylogenetically within the rest of Euphorbia such that it can't be cut out as a separate genus without either making a lot of genera that might not make sense or haveing a paraphyletic group (Chamaesyce is monophyletic but the recognition of Chamaesyces would make the rest of Euphorbia in what is now classified as E. subg. Chamaesyce paraphyletic). I'm still holding out some hope that the group can be teased apart into more genera in a way that morphologically makes sense but it doesn't look like it at this point. Another group classically treated as a separate genus is Pedilanthus which looks very different from most other Euphorbias. @connlindajo , My pleasure!
