A study of the latter can hardly be made from preparations where the mitochondrial technique has been used, for, although the plastids are stained, there is no indication as to what pigments they contain. So in the flower of Clivia nobilis, it can be seen that the orange-red pigment, carotin, arises directly from chondrio- conts. Small starch grains are first elaborated and, at the moment when these are absorbed, the carotin

A study of the latter can hardly be made from preparations where the mitochondrial technique has been used, for, although the plastids are stained, there is no indication as to what pigments they contain. So in the flower of Clivia nobilis, it can be seen that the orange-red pigment, carotin, arises directly from chondrio- conts. Small starch grains are first elaborated and, at the moment when these are absorbed, the carotinoid pigment arises in the in- terior of the chondrioconts as small grains or more especially as long needle-shaped crystals. In the flower of Sternbergia the chondrioconts form several acicular crjstals of carotin which give them the appearance of thick spindles. In other cases, the chondrio- somes in which the pigment will form are always chondrioconts
