本文还对E.检查cicutarium。埋葬首先取决于种子的裂缝的位置。种子更容易在大的裂缝中建立自己，即使他们的芒尾，芒毛和心皮尖端被实验去除。一旦进入裂缝，种子留在那里的概率和达到的深度在裂缝小的时候更大。在小裂缝，种子完整的芒和心皮达到更大的深度比那些没有这些结构。当裂缝小而常见时，种子在5次开卷-反冲循环后建立。在大裂缝中，需要8个周期才能建立;当裂缝较小且不频繁时，需要40个周期。
The self-planting mechanism of the hygroscopic seeds of E. cicutarium was examined. Burial depended first on the location of crevices by the seeds. The seeds were more likely to establish themselves in large crevices, even when their awn-tails, awn-hairs and carpel-tips were removed experimentally. Once in a crevice, the probability of a seed remaining there and the depth attained were greater when the crevices were small. In small crevices, seeds with intact awns and carpels attained greater depths than that of those without these structures. When crevices were small and common, the seeds became established after 5 uncoiling-recoiling cycles. In large crevices, 8 cycles were required for establishment; when crevices were small and infrequent, 40 cycles were required.
