Fig. 3

Transverse section diagram of the tissues in the Larix gmelinii var. japonica branch with well-developed rhytidome. Living secondary phloem (Sp) is composed of inner and outer part, i.e., conducting phloem (cSp) and non-conducting phloem (ncSp), respectively. Rhytidome (R) consists of dead and dying layers. The layers are constituted by the consecutive development of the periderm (Pe) and the separation from the non-conducting phloem. Other details: X secondary xylem, Vc vascular cambium, dSp dead secondary phloem, dPe developing periderm, Rc resin cavity, Rd resin duct, Ra ray
