La viviparidad es un fenómeno conocido sólo para un 0,1 % del total de especies, siendo menos frecuente en monocotiledóneas. En la familia Marantaceae solo había sido mencionado para la especie Marantochloa congensis. En este trabajo se presenta el primer registro de plantas originadas de semillas vivíparas de Goeppertia inocephala (Marantaceae) encontradas en el sotobosque de un bosque mixto de la región andina del departamento del Quindío, Colombia. La viviparidad de esta especie se discute en el contexto de los mecanismos de adaptación a las actuales condiciones ambientales y de pre-acondicionamiento de los ancestros paleotropicales
Heliconia montana and H. venusta are endemic to the tropical forests of the Central Andes. They belong to Heliconiaceae, a family recognized by the showy inflorescences of its members and hummingbird pollination. Both species were already established in 1983 but, just a few years later, the name H. montana was synonymized under the name H. venusta. Observations of populations of both species show that they differ by features evident in the field. A floral morphometric and a Principal Component analyses yielded also a clear cut distinction between H. montana and H. venusta. Therefore, Heliconia montana is reinstated here. The morphological features that differentiate H. montana and H. venusta are discussed, presented in a key, and illustrated with photographs.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
