Anatomy and Histochemistry of Leaf and Stem of Brazilian Endemic Species Mollinedia clavigera Tul.

Abstract

This study aimed to investigate the anatomy and histochemistry of Mollinedia clavigera leaves and stems through photonic microscopy and scanning electron microscopy. Noteworthy features of leaves were: presence of paracytic stomata on both surfaces; simple as well as bifurcate non-glandular trichomes; prismatic calcium oxalate crystals; flat-convex midrib with a central and two dorsal bundles; concave-convex HIGHLIGHTS  This is the first report of the microscopic study of Mollinedia clavigera  Light microscopy, SEM, EDS and histochemistry analysis were made to support anatomical and chemical characteristics  Non-glandular unicellular, long uniseriate, and short bifurcate trichomes were observed • Prismatic crystals of calcium oxalate were observed on the surfaces of leaves Homem, I.

“…This characteristic was not previously mentioned for the genus and thus helps with species identification. These crystals on the epidermis are uncommon but have been found in some genus, such as Mollinedia [ 32 ], Piper [ 20 ], and Talinum [ 33 ]. Several simple non-glandular trichomes with a thick wall were observed, especially on the abaxial side ( Figure 1 G).…”
