. The chloroplasts of two species of the Crassulaceae and their F 1 hybrid were compared by electron microscopy. The two species had contrasting leaf tissue δ 13 C values of −25°/ ∞ ( Sedum greggii ) and −13°/ ∞ ( Cremnophila linguifolia ), and the F 1 hybrid had a value of − 18°/ ∞ . S. greggii had a mean of 8.9 thylakoids per granum in contrast to C. linguifolia which had a mean of only 3.8 thylakoids per granum. The F 1 hybrid had a mean of 6.4 thylakoids per granum. Crystaloids were observed in S. greggii and the hybrid but not in C. linguifolia
