Vessels solitary with angular outline ; perforation plates scalariform ; intervessel pits and vessel - ray pitting alternate to scalariform ; helical thickenings only in vessel elements tails
導管橫切面為多角形，單管孔，散生。螺紋加厚僅出現導管分子尾端。梯狀穿孔為主。It was shown that vessel elements in secondary xylem of p. emblica have many different forms and most of them have tails and their perforation plates divide into two types : ( 1 ) there is one simple perforation plate at each end of the vessel elements and ( 2 ) there is one simple perforation plate at one end of the vessel elements and two simple perforation plate at the other end ; ( 3 ) a few vessel elements have special inclusions ; ( 4 ) the intervascular pits are alternate pits ; ( 5 ) the pits between the vessels and rays are mixed pits, pits with transverse gashes and scalariform pits
