Cristaliferous’ cells are found in the internal and external cortical and medullar parenchyma of E. Flowering tree at Milagres, Bahia, Brazil. Last update on Velutiina branch Photograph by: Greater stomatal density on the abaxial surface is common in species that occur in xeromorphic environments, a fact explained as a feature that minimizes water loss by ostiolar evapotranspiration Esau, ; Cutter, The vascular bundle is collateral closed, with angular collenchyma over and under the veins.
Flower of Erythrina velutina Willd. J Arnold Arboretum Stunning photographs of each species, brief details on the plant, its uses and how to grow it from seed.

Great grooves on the abaxial epidermis can be a diagnostic character to E.
In cross-sectional view, the leaf-blade presented branched trichomes with uniseriate stems Figure 6b. The anticlinal walls of epidermal cells are sinuous on both surfaces Figure 5a-d. Due to the similarities among the species, with the same pharmaceutical application, with external leaf blade and petiole and stem morphology of Erythrina velutina Willd.

The phenolic compounds are heterogeneous groups of substances that are present in almost erythhrina plants, inside the vacuole, cytoplasm or consisting the wall cell Fahn Anatomy of leaf and stem of Erythrina velutina. Fiber caps on the erythriha and phloem as well the crystals into the cells of vascular bundle sheaths also have been described for E. Furr M, Mahlberg PG Prismatic crystals are present inside the uniseriate layer of cells that involve the fibre cap around the vascular bundles on the mesophyll interior.

Dorsiventral mesophyll type is velutija recorded in the literature for the Erythrina genus, as in C. The identification of veluitna substance inside of these secretory cavities was not possible, which have an internal coating by periclinal flat or convex cells, arranged in a single layer Figure 3d. Secretory cavities in stem and leaf, types of trichomes and stomata, its location and distribution constitute diagnostic characters for this specie.
Authors contributions 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. A greater quantity of stomata was observed on the abaxial surface of the epidermis, similar to that recorded for Centrolobium tomentosum, E.
