The cytoplasm of the plant cell cytoplasmofplant00guil Year: 1941 Chapter VIII 77 The Chondriome {cont'd) It is difficult to check these phenomena by observation of living material. Roots in general do not lend themselves to this type of investigation. On the other hand, in the course of our research, we have found exceptionally favorable examples in which the entire process of elaboration of starch can be followed with remarkable accuracy in living cells. In a fragment of the epidermis of the anther of a young flower of Iris germanica examined in Ringer's solution, a chondriome is observed with great clearness, composed of thin, elongated, and undulating chondrioconts which sometimes branch, interspersed with granular mitochondria and short rods. In some cells there is no elaboration of starch; in others there may be seen several stages in the formation of small, compound, very refractive starch grains on the long axis of the chondrioconts. Similar phenomena may be observed in epidermal cells of the leaves, of the bracts, and of all very young floral parts. At later
