From: Phloem wedges in Malpighiaceae: origin, structure, diversification, and systematic relevance
Light micrographs showing phloem wedges inclusion in cross-sections. All sections were double-stained in safranin and Astra-blue. A, B Niedenzuella multiglandulosa. A The inclusion of wedges portions is given by the mechanical pressure exerted by the adjacent wood at both sides of the phloem wedges (W) (yellow dotted lines and arrowheads). B Once the portion of the phloem wedge is included (Ip), the adjacent regions of the wedges are in contact (yellow dotted lines and arrowheads). Scale bars A = 1 mm, B = 500 µm
