  • Summary Roots of 34 species out of 19 genera of Orchidaceae showing a peculiar modification of the cortical tissue were investigated by light- and scanning electron microscopy. The root cortex of these orchids is built up partially or totally by living tracheoidal cells. They form an almost velamen-like tissue (pseudovelamen). The anatomy and some developmental aspects of this cortical modification are analyzed. Functionally the velamen-like cortex is not involved in the rapid absorption of… CONTINUE READING
