PLANT FAMILY: Costaceae BOTANICAL NAME: Costus 'Red Baron' FORMAL SCIENTIFIC NAME: STATUS : CONTINENT: Neotropical SYNONYMS: BOTANICAL NOTES: This plant was found in the botanical garden at the University of Georgia Costa Rica campus at San Luis (near Monteverde). It appears to be closest to the described species Costus glaucus, but with shorter ligules and lacking the glaucus new stems that distinguish the species C. glaucus. It also has some characters of C. laevis but clearly is not that species. I asked about the origin of the plant and Lucas Ramirez told me it was collected in the Rio Penas Blancas valley on the other side of the Continental Divide. He said he had been told by indigenous people that this plant had superior medicinal qualities and to look for the darker stems. Later we crossed the Divide and went down into the valley where I saw this plant growing in the wild. Therefor it does not seem likely this is just a one-time ocurrence or natural hybrid but either a distinct species or an undescribed variety of C. glaucus or C. laevis. For now, I have decided to give this plant a new cultivar name, and if it can be successfully propagated, I believe it is worthy of cultivation in gardens, or at the least worth further study to determine its appropriate classification. Upon reflection, I have also concluded that this is the same species as a plant I found in 2006 at Pocosol in the same watershed, but had incorrectly placed it as C. aff. laevis. Whether it is a form of C. glaucus or a new undescribed species, I will leave that up to the taxonomists to ultimately decide, but for now it is Costus 'Red Baron'.
