Changes in the distribution of iron during the embryo sac formation of Hemerocallis middendorffii var. esculenta were cytochemically examined. Iron was detected as Prussian blue products of various forms. The reaction products were not observed in the early stages of the megaspore, but they appeared in some cells in the chalazal region of the nucellus. The degenerating nucellar cells around the megaspore also had a number of small granular reaction products.
In the mature embryo sac, the egg contained a number of small granular products around the nucleus, and a few products were observed under the filiform apparatus of the synergids in some preparates. The degenerating antipodals and the central cell contained a cluster of granular products or the products of the complicate shape. The reason for the difference in the distribution of iron between Hemerocallis and Lilium is still unknown.
