  Hello, I have a question regarding the key for Fabaceae. At question 22, it asks whether the leaves are paripinnate or imparipinnate. In the key, Chamaecrista is imparipinnate (has a terminal leaflet). However, in all of the pictures on the website, the leaves appear to lack a terminal leaflet. Is there something I'm missing here?

  Answer

  Dear SigFig, There was an error in the key, and Chamaecrista should be included under 22a with the species that are parapinnate. It is distinguished from species in 22a by the distinct (not fused) stamens, distinct sepals, resupinate flowers, and evident petiolar gland (not found in the other species of that lead). Best wishes.
