It's not often pteridophytes make the news, and as someone who collected pteridophytes in New Caledonia forty years ago (and certainly came across Tmsipteris, though I can't see a record of having collected it), I'm rather chuffed.

(News reports keep calling it a fern. I can't quite remember all the taxonomy, but it's Psilotales, and I don't think that's ferns. I'll have to dig out my copy of Sporne to check it out.)
