FIG. 3 in Populations of a new morphotype of corrugate Lessonia Bory in the Beagle Channel, sub-Antarctic Magellanic ecoregion: a possible case of on-going speciation

FIG. 3. — Internal morphology of the corrugate Lessonia Bory: A, small angular meristodermal cells on the surface of blade; B, transverse section through a sterile portion of the blade; C, detail of meristoderm and cortex showing cells with full (right arrow) and reduced (left arrow) protoplast and golden bodies in outer cortex and mid cortex; and rounded light refracting bodies (arrowheads); D, detail of medulla showing cylindrical cells (arrow) and some elongated filaments (arrowhead) immersed in a dense intercellular matrix; E, surface view of a sorus; F, transverse section through a sorus; G, detail of sorus. Abbreviations: mer, meristoderm; oc, outer cortex; mc, mid cortex; ic, inner cortex; m, medulla; p, paraphyses; l, part of the lacuna; s, sporangia. Scale bars: A, 15 µm; B, 50 µm; C, G, 20 µm; D, E, 40 µm; F, 30 µm.
