“…This chemical composition and the shapes of crystals suggest that these crystals are composed of calcium oxalate. Recently, several authors have reported the chemical composition of the crystals using energy dispersive x‐ray spectroscopy (Brito et al, 2021; D'Almeida et al, 2021; Klider et al, 2021; Raman et al, 2022). Calcium oxalate crystals were also found in O. porosa (Brustulim et al, 2020).…”

This article describes the morpho-anatomies of the leaves and stems of Ocotea paranaensis Brotto, Baitello, Cervi & Santos (Lauraceae) using light and scanning electron microscopy. The main anatomical features characterizing the species are the presence of simple non-glandular trichomes in the leaves and stems, large secretory cells in the leaves, flat-convex petioles with two small lateral ribs, brachysclereids in the stem cortex and pith, and the presence of starch grains and various types of calcium oxalate crystals in the pith. Histochemical tests indicated the presence of lignin in stone cells, fibers, and xylem. Lipophilic contents were found in the secretory cells.Phenolic compounds were detected in the epidermis, hypodermis, phloem, and xylem. The present study's findings can contribute to the taxonomy and authentication of O. paranaensis. Research highlights• This article is the first morpho-anatomical study of Ocotea paranaensis.• Anatomy and histochemistry of the leaves and stems were studied by light microscopy, FESEM and EDS.• The findings of this study would aid in the species identification and taxonomy.

“…The presence of crystals in plants is common and may be formed in any organ or tissue. They usually occur in the stems (Brustulim et al, 2020) and leaves (Klider et al, 2020) and can be deposited in different tissues and locations, such as within epidermal cells (Traesel et al, 2017), externally to the epidermis (Almeida et al, 2020), in the mesophyll (Tirloni et al, 2018), and in the cortex and pith (D'Almeida et al, 2021) of the stem. They present a great variety of morphologies, such as prisms of different shapes, druses, styloid, and crystal sand, and are useful in the species identification.…”

“…However, other compositions can also occur, such as calcium carbonate (CaCO 3 ) crystals, or even silica crystals (SiO 2 ) (Bosqueiro, 1995;Webb, 1999). Crystals in plants have been reported as calcium oxalate using EDS in many studies (Lersten & Horner, 2011;Saulle et al, 2018;Santos et al, 2018;Almeida et al, 2020;Klider et al, 2020;Brito et al, 2021;D'Almeida et al, 2021;Pauzer et al, 2021;Gribner et al, 2022). Only a few studies have reported calcium sulfate crystals (Storey & Thomson, 1994;Pritchard et al, 2000;He et al, 2012).…”

This study provides a comprehensive account of the various types of calcium oxalate crystals found in the genus Baccharis and assesses the exceptional value of crystal macropatterns for the taxonomy of the genus. The morphotype, occurrence and chemical composition of the crystals found in the stems and leaves are studied. The 44 species included in this study were selected based on a broad phylogeny-based sampling covering seven subgenera and 31 sections. These species were chosen to represent all the main phylogenetic lineages of Baccharis; thus, the sampling also represents a comprehensive coverage concerning evolutionary significance for such a large and environmentally and economically important plant group. The samples were analyzed by light microscopy, scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDS). Several morphotypes of crystals, including druses, crystal sand, styloids and prisms, were present. Based on their chemical composition, the crystals were classified as pure calcium oxalate, mixtures of oxalates and sulfates, and mixtures of oxalates, sulfates and silica. The crystal macropatterns observed in this study aid in the species identification and provide novel data for the taxonomy of Baccharis.
