Type locality: On Volcano of Colima, Mexico.
Distribution: Known only from the type locality.
Dr. Rose saw flowers of this plant in the herbarium of the Botanical Garden at Berlin in 1912 and noted that it was a Rathbunia; otherwise it is known to us only from description. In transferring it to Rathbunia (loc. cit.) we associated specimens with it from Sinaloa and Tepic, Mexico, which now appear better referable to Rathbunia alamosensis, although the flowers are longer than in typical specimens (8 to 10 cm. long) and somewhat curved."
