Resumo: | A study on the vegetative organ anatomy of Ianthopappus corymbosus was conducted in order to provide a basis for comparison with the genus Richterago, since this species had been previously included in that genus. The anatomical characters of I. corymbosus that support its exclusion from the genus Richteragon are: epithelial cell organization of adventitious root secretory canals, non-glandular trichomes, and presence of cortical vascular bundles in the stem. In Ianthopappus corymbosus, the underground system consists of rhizophore from which adventitious roots branch off. The subapical meristem of the adventitious root revealed that the ground meristem forms the inner layer which in a meristematic phase, forms 2/3 of the cortex. This layer will differentiate in the endodermis, with Casparian strips, and is referred to as meristematic endodermis. Endodermic secretory canals, limited by four epithelial cells, appear in the region adjacent to the primary phloem. |
