Spindle membrane in meiosis of pollen mother cells of Tradescantia and in mitosis of endosperm cells of Zephyranthes.
In the previous paper (Wada, Nagao and Awasawa 1963), we have demonstrated the presence of spindle membrane in fixed preparations of root tip cells in Vicia faba and Allium cepa. These materials are most familiar in the laboratory for observations of mitosis in somatic cells and their mitotic figures are described in text-books of cytology as a standard type of somatic cell division. In this pa...
