This is a hybrid by Frances Batcheller. It is a cross of C. panamensis and C. melittifolia, the same parentage as C. ‘Caribbean Pink’. It is reported in the information on a herbarium specimen at the Smithsonian as an F2 hybrid, meaning that it is a seedling grown from the original cross. At the time, the two species involved were known as Nautilocalys villosus and N. melittifolius.
