ABSTRACT
Abstract Limonium brasiliense (Boiss.) Kuntze, Plumbaginaceae, is a coastal herb of the Southern Brazilian states and Rio de Janeiro State. In folk medicine, it is used in the treatment of female genitourinary tract infections and menstrual cycle irregularities. The aim of this study was to describe morpho-anatomical characters with details on venation pattern of L. brasiliense leaves, collected on the coast of Rio Grande do Sul State, in Southern Brazil. Leaf samples fixed in FAA50 (5% formaldehyde, 5% acetic acid and 90% ethanol: water mixture 50:50 v/v) and 1% glutaraldehyde and preserved in 70% ethanol, were histologically sectioned and analyzed by light and scanning electron microscopy. The L. brasiliense leaves were simple, entire, incomplete, oboval-lanceolate, venation penninervous and showed rosulated phyllotaxy, entire and revolute margin, with apex rounded to slightly retuse, base attenuate and venation pattern brochidodromous. On microscopic analysis, these leaves showed a thick and striated cuticle, salt glands, isobilateral mesophyll thicker in the apical region of the leaf blade, abundant aerenchyma in the petiole and main vein, collateral vascular bundles surrounded by fiber-sclereids, lipid substances in the cuticle and polyphenols in phloem cells.
