Descripción:Valeriana prionophylla (Valerianaceae) phenology in Costa Rican paramo. Valeriana prionophylla (Valerianaceae) is a medicinal plant used primarily to treat nervous disorders and respiratory problems. In Costa Rica it is found at 2 800-3 700 meters over sea level in Central Pacific Conservation Area and “Amistad Pacifica” Conservation Areas as well. Due to its medicinal importance, there has been various analysis done regarding its phenological aspects in wild populations.  Two plots of 88m2 were observed, and from December 2010 to September 2012 the phenological elements associated with their growth and spread were studied monthly. It was found that between May and September an asynchronous phenological behavior took place between plants and phenophases: floral tube, flower bud, unfertilized flowers, fertilized flowers and seeds. Exist a positive relation between precipitation and unfertilized flower (p=0.657) and fertilized flower (p=0.641). The appearance of the first phenological stage, the floral tube, matches with the beginning of the rainy season in the area. Only has one phenological period during the year.
