FIG. 5 in Structural and histochemical characterization of the osmophores in corollas of Asteraceae (tribes Onoserideae and Famatinantheae)

FIG. 5. — Osmophore elements in Famatinanthus and Plazia: A, two teeth of the marginal corolla showing the venation in Plazia daphnoides Wedd., note the two veins at each tooth margin joining at the apex (Safranin); B, sinus between the outer and the inner lips of the marginal corolla in Famatinanthus decussatus (Hieron.) Ariza & S.E. Freire showing starch grains (IKI);C, D, Plazia daphnoides; C, transection of the marginal corolla showing stomata with large substomatal chambers (Safranin-Astra Blue); D, abaxial surface view of one sinus of the central corolla, showing numerous stomata (arrows) near the osmophoric area (Safranin); E, apex of one lobe of the central corolla in Famatinanthus decusssatus, showing one large stomata and a cluster of starch grains below (TIOFH3); F, G, Plazia daphnoides; F, detail of one corolla stoma at the sinus area (Safranin); G, detail of one corolla stoma showing starch content as dark dots (IKI).Abbreviations:SM, starch mass;ST, stomata;VE, vein.A, D, F, Ruthsatz s.n.
