Abstract
The gametophytes, embryogeny and pericarp of the orchidGoodyera repens are described. The anther wall consists of an epidermis, fibrous endothecium, middle layer and a uniseriate tapetum of binucleate cells. Meiosis is normal. Decussate, isobilateral, linear and tetrahedral pollen tetrads are formed. At shedding the massulae are 2-celled. Ovules are anatropous, bitegmic and tenuinucellate. The inner integrument alone forms the micropyle. Development of the female gametophyte is monosporic. The primary endosperm nucleus degenerates without and division. Development of embryo corresponds to the Asterad type. the mature embryo lacks differentiation. The seeds are minute and nonendospermic. The seed coat is formed entirely by the outer layer of testa.
