Proposed introgression events (from Table 2) mapped onto the ASTRAL topology as a visual representation of hypothesized gene flow. Solid red arrows represent proposed hybridization ancestral to a clade; dotted lines represent hybridization among species or populations only; asterisks mark taxa where there was evidence for introgression but the source of the organellar DNA was unresolved.

将来自表2的推定渐渗（introgression）事件映射至ASTRAL拓扑结构，以可视化形式呈现假设的基因流。实心红色箭头代表对应某一演化支（clade）祖先的推定杂交事件；虚线仅代表物种或种群间的杂交；星号则标记存在渐渗证据但细胞器DNA（organellar DNA）来源未明确的类群。
