For the two leaf-replacing forms, leaves are marked so that growth can be measured by
punching through the leaves within the leaf sheath, while for the two non-leaf-replacing
forms, leaves are marked for measuring by clipping off part of the leaf or plants are marked
for measurement by rhizome tagging. Clipping to mark a leaf, as described here, is distinct
from "leaf clipping" methods that remove all leaf material from a known area and check for
regrowth (Hauxwell et al. 2001). In all cases, marking enables one to differentiate existing
tissue at the time of marking from leaves or other plant parts produced after the mark is
made. In the two di-meristematic forms, rhizomes are marked by tagging the rhizome at a
known spot relative to the growing rhizome meristem and new growth beyond the mark is
measured after a time interval.
