The vascular system in the rhizome of ginger (Zingiber officinale R.) is arranged in three distinct systems: an inner system that form the principal vascular system of the rhizome, an intermediated system originating a thin camada of anastomosing vascular strands, having direct contact with the inner system and an outer system free of the anastomosis with the another vascular systems. The intermediated and inner system are associated with the root insertion and whole systems are relacioned with the formation of bud adventicious maintaing the same pattern of the rhizome and the communication between the outer and inner system occurs through the bridging to inner system leaf traces.
