This is a test on how to include additional information. The scans are from Volume III of the manual de Plantas de Costa Rica. I have included a scan of the keys for Stelis (prepared by Luer) ; the descriptions for cooperi, tridentata (since it was mentioned in the discussion in the original submission), argentata (since it is paired with cooperi in the key) and, superbiens ( since it is closely related to argentata and the description for argentata raises the very high chance of intermediate forms with superbiens.)
