Abstract: 
Vegetative growth in the orchid Dimerandra emarginatawas assessed in more than 300 individual plants growing on the host tree Annona glabra.For each growing season D. emarginata develops one vertical shoot which persists over several years. Past growth was quantified by comparing stem lengths of subsequent years. Average yearly stem height increments were estimated for different plant sizes and used to model long-term growth, which proved to be very slow. The implications of slow growth for age estimates, survival, and community processes are discussed.
