| Summary: | Bibliography: leaves 100-133. === Desiccation tolerance of the inner leaves of Eragrostis nindensis is compared with the desiccation sensitivity of the outer leaves, as well as those of the closely related species, E. curvula. Both E. nindensis and E. curvula dehydrate to a relative water content (RWC) ofless than 5% in two weeks. Photosynthetic activity in E. curvula is maintained down to 40% RWC, after which further drying results in a sudden irreversible breakdown of the photosynthetic system and its pigments. |
