FIG. 1. — Nodal configurations of Mallotus nudiflorus (L.) Kulju & Welzen: A, trilacunar three traces for both cotyledonary leaves; B, trilacunar three traces for first alternate green leaves in seedling; C, D, typical trilacunar three traces situation for both the oppo- site leaves; E-G, left side with two separate lateral traces and right side with a "split-lateral"; H-J, left side with two separate traces within a single gap and right side with very closely approximated two traces with separate gaps, note the tiny part of parent vascular cylinder in between the traces (I); K-M, left side with two separate traces within a single gap and right side with a "split-lateral" (note sclerenchymatous layer absent); N-P; typical "split-lateral" situation for both the opposite leaves, note initiation of division of "splitlaterals" (O). Abbreviations: lt, lateral trace; mt, median trace; pc, parent vascular cylinder, sl, split lateral; p, phloem; s, sclerenchyma; x, xylem. Scale bars: A, B, 1 mm; C, D, 5 mm; E-P, 4 mm.
