同域种群的Eaclus canadensis和Eaclus virginicus在中南部俄克拉荷马州发现许多植物与中间形态，从而表明杂交和渐渗的两个物种。对140株水稻的花序、颖片、外稃等8个性状进行了测定，并分析了其变异规律。分析表明，这些个体可被识别为E。弗吉尼亚变种glabriflorus和F1杂种或回交和渐渗类型。
Sympatric populations of Elymus canadensis and Elymus virginicus in southcentral Oklahoma revealed numerous plants with intermediate morphology, thus suggesting hybridization and introgression of the two species. Eight characters of the infloresence, glumes, and lemmas of 140 plants were measured and the variation patterns analyzed. Analysis suggests individuals identifiable as E. virginicus var. glabriflorus and F1 hybrids or backcrossed and introgressed types.
