Southern African grasses with foliage that revives after dehydration

Abstract

A brief survey in Southern Africa revealed 11 grass species and a number of sedges with foliage that recovers from air-drying (equivalent to equilibrium with air at 20-40 % relative humidity at 28° C.). The desiccation tolerance limits were extremely low being equivalent to approximately 0-5  % relative humidity. Some species may have a potential use in agriculture.
