44 - 46. LEAF RANK Leaf rank is a semiquantitative description of the regularity of the leaf’s vein system, from an arbitrary level of 1r for the lowest rank or level of organization to 4r for the highest. The rank number corresponds to the highest order of veins that is well organized. The table on the next page gives the characters that define the ranks. 1r 2r ~3X ~3X 2° 2° 1° ~7X ~1X ~7 X ~1X Schisandra glaucescens (Schisandraceae) Polyscias guilfoylei (Araliaceae) Fig. 1 Fig. 2 3r 4r ~3X ~3X 2° 2° ~7X ~7X ~1X ~1X Toona sureni (Meliaceae) Fagus tientaiensis (Fagaceae) Fig.
