Proner has proved the presence of sedoheptulose in Sedum acre L., S. boloniense Lois., and reflexum L. Bennet-Clark reported its presence in S. praealtum A. de C. Nordal ° identified sedoheptulose conclusively in S. acre, L., S. album L., S. roseum (L.) Scop., S. spurium M.-B., and S. Telephium L., and concluded from qualitative color reactions that sedoheptulose is widely distributed within the family Crassu-laceae, but it is not always present. The experiments of Wolf have made it appear highly probable that sedoheptulose occurs in Bryophyllum calycinum Salisb. and Sempervivum glaucum Tenore.

Extensive research by Richards (1915), Bennet-Clark (1933 a, b). Wolf (1937), and then by such investigators as Pucher, Vickery, Thomas, Beevers, and Ranson firmly established the relationship between dark COj fixation and organic acid synthesis in succulent plants. Furthermore, during this early period before 1950 it was clear that the organic acids which accumulated during the dark phase, termed acidification by the early workers, were nearly quantitatively converted to carbohydrates (viz., starch) during the subsequent light or deacidification period (see Bennet-Clark, 1933 for example).

It is generally accepted that low night and high day temperatures are correlated with enhanced CAM activity (e.g., Vickery, 1954 Bennet-Clark, 1933a, b Queiroz, 1965,1966).
