The article comprises investigation of the adventitious root, rhizome and leaf anatomy of an aquatic perennial herb Anubias barteri var. nana.
The anatomical characteristics of the adventitious roots exhibit a primary structure but some specific histological features such as the exodermis, endodermis and stele are present (Figs. 1, A, B, 2).
The rhizome discloses a cortex with large intercellular spaces and a number of amphivasal and collateral bundles, embedded in the ground tissue are present (Figs. 3, A, B; 4).
The petiole of both species is polistelic with regular and aleatory arrangement of the vascular bundles, embedded in aerenchyma.
The petiole cortex is differentiated into two regions (Fig. 5, A, B). The blade possesses a homogenous mesophyll with few small air chambers (Fig. 6, A).
The midrib is polistelic with poor-developed collateral vascular bundles (Fig. 6, B, 7).
The anatomy of the vegetal organs of this two Anubias barteri var. nana discloses certain features of anatomical and ecological interest. |
