Secretory tissues in plants. Date 21 August Erythrina velutina is a species of leguminous tree. There are, approximately, 12 collateral vascular bundles, with cells of thickness circumference with lignified cell walls.

The angular collenchyma Figure 2b is observed immediately under the epidermis with layers of cells. The external cortical parenchyma cells exhibit inter cellular spaces of various dimensions Figure 4a4b. MMBS MSc student and ASCOS undergraduate student contributed in plant sample identification, confection of herbarium, running the laboratory work, analysis of the data and drafted the paper.

If the file has been modified from its original state, some details such as the timestamp may not fully reflect those of the original file.

In cross-sectional view, the leaf-blade presented branched trichomes with uniseriate stems Figure 6b. Among the genres with native species, more common in the northeast region are Phaseolus, Crotalaria, Erytrhina, Andira, Sophora, Indigofera and Mucunaamong others Judd et al. Prismatic crystals are present inside the uniseriate layer of cells that involve the fibre cap around the vascular bundles on the mesophyll interior.


The stomata density on the abaxial surface was This file contains additional information such as Exif metadata which may have been added by the digital camera, scanner, or software program used to create or digitize it. According to Joly is one of families with the greatest representative numbers in the dicotyledons. The structural characterization of the stem and leaf allows its distinction from other ones of this genus, ensuring safety for commercial pharmacological uses, allowing certification of the authenticity of raw material.

Sinuous anticlinal walls were observed in E.

The same was true to indolic alkaloids, mainly the erythrinic type Almeida, The presence of secretory cavities in the stem and leaf, types of trichomes and stomata, its location and distribution in the leaf epidermis constitute diagnostic-characters that are important for an accurate and safe identification for E. Santana I ; Rejane M.

The inflorescence is fascicle type, presenting orangish flowers. Anatomy of the dicotyledons: Methodology The samples were fixed in FAA 50, and subsequently semipermanent histological slides were prepared, containing crosssections and paradermal sections of the material previously prepared, following normal plant anatomy procedures Sass, ; Johansen, The petiole presents a uniseriate epidermis, branched trichomes, covered by a thickened cuticle, followed by three to four layers of angular collenchyma.

Publisher University of Wisconsin Year ISBN Description An amazing and comprehensive work, giving a brief guide to the many genera of the family Fabaceae and also the principle uses of the genus.

The Sudam reaction detected total lipids in cuticle and branched trichomes The presence of alkaloids in parenchyma cells and secretory cavities in the stem, in glandular, tector and capitate glandular trichomes in the leaf are according to the literature findings to the genus Erythrina Virtuoso, References Almeida EE The vascular bundles, in the lower caliber leaf vein region of the show sheath extensions in the direction of the adaxial surface and fiber cap on the xylem and the phloem Figure 6c.

In the region of the phloem, the secretory structures have various sizes Figure 3d. In the celutina surface, epidermal cells on the veins have prismatic crystals on their interior.
