ZUR OKOLOGIE VON MONOCHAETUM MERIDENSE UND MONOCHAETUM BONPLANDII IM NEBELWALD DER SIERRA NEVADA DE SANTA MARTA

Abstract

In the cloud forest of San Lorenzo (2050 m) near Santa Marta temperature and relative humidity were registrated for 24 hours. During this time variation of weight from leaves, caused by dew, was noted from two species of the genus Monochaetum (Melastomataceae). Anatomy of those leaves was analysed and discussed in relation to fine structure of cuticle, edaphic factors and differences of weight. Evolution of epiphytic characteristics on terresterial Melastomataceae was analized im comparison to the other species of Monochaetum from Sierra Nevada.
