ABSTRACT
A description of the leaf anatomy of two rosette plants that grow at 4.040 m, Oritrophium paramense and O. Peruvianum is dealt with. The common and differential features that enable them to adapt themselves to the Páramo enviroment where they are submited to conditions of intense radiation, low temperatures, physiological water stress and strong winds, are supplied. In O. peruvianum the presence of numerous fungi hyphes that intermix with the tricomes of the indumentum of the adaxial side is described and their probable function is suggested.
