Abstract

The morphological ultrastructure of the various types of trichomes of Utricularia biflora was investigated using the scanning electron microscope. The mature utricle can be characterized as having specific types of trichomes ornamenting the following regions: the external surface, entrance, threshold, and pavement epithelium, and the internal utricle surface. The complex morphological relationship among the door, velum, and pavement epithelial zones is clearly elucidated using scanning electron microscopy.
