The Trujillo 8464 collection from Estado Merida is the only collection known outside of the Coastal Cordillera. The corollas are 5.5-6 mm long and the hypanthium 4 mm long, thus measuring somewhat smaller than in material from the Coastal Cordillera. The external surface of the corolla tube of the Merida specimens shows perhaps somewhat more uniformity of puberulence as contrasted with the specimens from the Coastal Cordillera, in which the pubescence appears as vertical lines of strigose or appressed hairs mainly on the lower portion of the tube. However, these differences appear to be too minute to warrant any separation at this time. The leaf shape and pubescence appears identical in both the material from Merida and that from the Coastal Cordillera.
