1. Horseradish roots reach a stage of 'ripeness to regenerate' at the age of 1-2 months, when secondary thickening has begun, a phellogen has formed, and the primary cortex has been shed; provided that they are then detached from the parent plant. 2. New primordia arise (as is already known) only in association with the scars of lateral roots ; but they are produced, not as previously believed from a callus, but individually as organized meristems whose cells are derived only from the phellogen of the main root. 3. The primordia appear to be undetermined ('indifferent') in nature; their subsequent differentiation into buds or roots is described.
