FIGURE 4 in The hydrochorous Amazonian genus Glandonia (Malpighiaceae): new records, morphoanatomy updates and taxonomic contributions

FIGURE 4. Anatomical characters of Glandonia species. A. Adaxial surface of G. macrocarpa showing indument scars (black arrow). B. Abaxial surface of G. prancei showing a stoma (black arrow) and sinuous outline of the anticlinal epidermal wall. Abaxial surface of G. williamsii C. papillae covering a stoma (black arrow), D. papillose surface (SEM image), a stoma (white arrow). E. Transversal section of leaf of G. williamsii, papillae (white arrow), F. Sclereids in midrib of G. macrocarpa (black arrow). Diagrammatic schemas of petiolar vascular systems G. a curved arc with invaginated ends in G. prancei and H. a concentric arc delimiting a central pith in G. macrocarpa, dot-filled areas: phloem, striped areas: xylem. Leaf blade cleared I. in G. williamsii and J. in G. prancei, note the laminar gland (arrow). Transversal view of bracteole gland K. convex surface in G. macrocarpa, L. truncate surface in G. prancei. M–O. Sclereids on posterior petal of G. williamsii, N. Macrosclereids, O. Brachysclereids.
