Abstract

At altitudes below 1300 m most species of grasses in tropical Africa are ones that use 4carbon photosynthesis Above 4000 m only species of the subfamily Pooideae using 3carbon photosynthesis are found At intermediate altitudes the percent of 3carbon genera and species in the grass flora is a very regular function of altitude The correlate of altitude that controls the distribution of grasses appears to be temperature Fossil grass cuticles are identifiable to genus and should provide a useful paleothermometer If no other errors were involved the regular altitudinal distribution of genera in the flora of tropical East Africa would permit paleotemperature estimates with 95 confidence limits of ± 12°C
