Morfología y anatomía foliar de Jodina rhombifolia (Hook. y Arn.) Reissek (Santalaceae)
Ruiz, Ana Inés; María I. Mercado & Graciela I. Ponessa. 2007. “Foliar morphology and anatomy of Jodina rhombifolia (Hook. and Arn.) Reissek (Santalaceae)”. Lilloa 44 (1-2). In Argentina Santalaceae family includes six genera with ten species. Jodina genus is represented in our country only by one species, Jodina rhombifolia. Objective: foliar anatomy study of specimens collected in 1999 in Trancas department (Tucumán). J. rhombifolia leaves are alternate, rhombic, leathey, with pinnate, camptodrome brochidodrome venation. Anatomical features are: isolateral mesophill, amphistomatic leaves, polygonal epidermal cells with slightly sinuous anticlinal walls and numerous primary pitt fields. Sunk parasytic stomata complex, are surrounded by the neighboring epidermal cells. Multiple collenchymatous epidermal cells, with anticlinal and periclinal thicked walls and rhombic solitary calcium oxalate crystals. Pallisade chlorenchyma exhibit two layers of rectangular cells in adaxial position and one layer in abaxial position, calcium oxalate crystals (rhombic and druses) are present. Spongy chlorenchyma has cells with abundant intercellular spaces. The middle collateral vascular bundle presents sclerenchymatic fiber sheath in phloem and xilem. The petiole presents subtriangular shape, one collateral vascular bundle, calcium oxalate crystals (rhombic and druses) in cortical parenchyma cells.
