Leitneria is a somewhat mysterious and obscure genus consisting of two species in the US and occurring nowhere else. It was once placed in its own family but today has been taxonomically placed in the Ailanthus family, Simaroubaceae. According to Flora of North America, it has a fossil record dating back to the Oligocene.
I first encountered it in Texas five years ago, and again it was in a small population that was nestled next to the road and generally unappreciated and unnoted by the general public, despite how weird the trees look compared to anything else. What mystifies me about this genus is its scattered, sporadic and small distribution in Southeastern North America and the fact that evolutionarily it is on its own little lonely branch and never seemed to diversify or spread, and if it did, those populations and other species are now extinct.
This episode was totally worth the poison oak that I
got.
