A study of a number of morphological characters confirms the presence of a hybrid between the two species of Costa Rican Gunnera, G. insignis and G. talamancana. Despite wind pollination and similar habitat preferences among all known species, hybrids of Gunnera are rare in nature because the disturbed sites they prefer are so small and labile. Road building, especially of the Pan-American Highway, has established large areas of more or less permanently disturbed habitat allowing the populations of the two different species to interdigitate and hybridize.
