artifact description
Light and electron microscopy was employed to study the morphology and development of the bracteal nectaries of several species of Aphelandra (Acanthaceae). Special emphasis was given to the sub-secretory cells that show striking differences in wall structure and cytoplasmic detail when compared to the cells of the adjacent secretory layer. The appearance and location of these cells in the nectary are considered in the over-all functioning of this gland.
