Variation in pollen size in transplanted clones of four widespread prairie grasses was correlated geographically. Pubescent, non—glaucous clones of Andropogon gerardi Vitman, Andropogon scoparius Michx., and Sorghastrum nutans (L.) Nash, as well as non—glaucous clones of Panicum virgatum L. from eastern Texas, had larger pollen grains than non—pubescent, glaucous clones of these species from central Texas and non—pubescent, glaucous P. virgatum from north—central Texas under garden conditions.
