This species propagates vegetatively by extension of horizontal rhizomes resulting in programmed reiteration of apical and/or axillary meristems. The rhizome connection is persistent after the new ramet establishment. In order to investigate the photosynthate translocation between the ortet and the daughter ramet through the rhizome in the species and the ecological signific...
