Abstract
Two new species of Conyza (Asteraceae, Astereae) are proposed: C. chionea and C. perijaensis. The first one, from Nevado del Ruíz (Caldas), is close to C. primulaefolia but differs in the kind of inflorescence, the number of series of bracts, and female and hermaphrodite florets. Conyza perijanensis, from the Serranía del Perijá (Cesar) and with populations from Guajira, is similar to C. mima but it diverges from that in having female florets slightly ligulated.
