These may either form directly by transforma- tion of small leucoplasts, which may or may not have previously formed starch, or they may, in other cases, arise by a metamorpho- sis of chloroplasts whose chlorophyll disappears and is then re- placed by a carotinoid. Pigment may appear in the chromoplast either in the amorphous or in the crystalline state. In the former, which is always the case when the pigment is xanthophyll, the chromoplasts affect the same globular or lenticular form as the chloroplasts. In the crystalline state, which is frequently the case when the pigment is carotin, the crystals are contained in variable number in the chromoplasts, and usually take the form of needles
