ABSTRACT

ABSTRACT Leaf glands are common structures in Malpighiaceae and exhibit great morphological diversity, yet information on their anatomy, secretion and type of visitors remains scarce. Th e aim of this study was to describe the distribution, anatomical development and chemical and functional properties of leaf glands of Banisteriopsis muricata (Malpighiaceae). Leaves at diff erent stages of development were collected and processed according to standard techniques for light and scanning electron microscopy. Secretion composition was determined by histochemical tests and test-strips, while gland funciton was determined by fi eld observation of interactions with visitors. Leaf glands were located on the petiole and on the abaxial base of the leaf blade. Th e gland secretion was found to be a protein-rich nectar that was foraged upon by ants ( Solenopsis ); it was found accumulated in subcuticular spaces without pores or stomata for its release. Leaf glands were found to develop from protoderm and ground meristem, and consisted of typical secretory epidermis, nectariferous parenchyma and vascularized subnectariferous parenchyma. Th erefore, it can be concluded that the distribution, chemical nature of secretion and anatomy of leaf glands of
