The Kranz syndrome, as indicated by relatively high 13 C/ 12 C ratios is characteristic of 16 ½ tribes and about ½ of the species of the Gramineae. Data are given for 198 species from 129 genera and 47 tribes, and from at least 6 subfamilies of grasses. This information is correlated with data from the literature on anatomical and physiological characters of both Kranz and non‐Kranz grasses. All subfamilies, tribes, and genera seem to be uniformly all Kranz or non‐Kranz except the subfamily Panicoideae and the genus Panicum which have both Kranz and non‐Kranz species represented.
