图3 鼠尾草各居群不同传粉者的传粉模式。毛地黄鼠尾草(干河坝)居群I: 背部传粉(A、C)和腹部传粉(B); 毛地黄鼠尾草(甘海子)居群II: 背部传粉(D); 圆苞鼠尾草居群: 背部传粉(E)和腹部传粉(F); 近掌脉鼠尾草居群: 背部传粉(G、I)和腹部传粉(H)。

Fig. 3 Pollination modes of different pollinators in each population of Salvia. Population I of S. digitaloides in Ganheba: dorsal pollinations by bigger Bombus friseanus (A) and B. personatus (C), and ventral pollinations by smaller B. friseanus (B); population II of S. digitaloides in Dongbagu: dorsal pollination by Psithyrus sp. (D); population of S. cyclostegia: dorsal pollinations by B. personatus (E) and ventral pollinations by smaller B. friseanus (F); population of S. subpalmatinervis: dorsal pollinations by bigger B. friseanus (G) and B. personatus (I), and ventral pollinations by smaller B. friseanus (H).
