Fig. 5

Light micrographs of stem cross-sections in Malpighiaceae showing phloem wedges diversity. All sections were double-stained in safranin and Astra-blue. A Peixotoa sericea with 6 phloem wedges. Note xylem under the phloem wedges is different from that of interwedges, with fewer vessels and more fibers. B Mascagnia sepium showing approximately 15 phloem wedges some deeper than the others, because of their different formation onset times. C Niedenzuella multiglandulosa showing 8–12 phloem wedges of different ages, some being deeper than the others D Stigmaphyllon blanchetii showing 6 phloem wedges generating marked concavities in the stem. E Mascagnia divaricata showing at least 4 well-formed phloem wedges. F Alicia anisopetala showing 9 well-formed phloem wedges. G Tristellateia greveana showing 8 phloem wedges, without apparently forming depressions in the stem. H Tristellateia australasiae showing 8 well-formed phloem wedges slightly marking concavities on the stem. Images not to scale
