Origin and Habitat: Hills Between General Cepeda and La Rosa, foot-hills and adjacent areas up to the Sierra de Paila. The plants grow among the shrubs and grasses or hidden amid fragmented stones of brown lime-rocks on fine sediment. They are almost exlusively found on the north side of small hill-formations elevating not more than 10 meters from the plain. The habitat isĀ located 1.100-1450 metersĀ above sea-level and wind is blowing most the time.
