沙氏耳草（Hedyotis salzmannii）为茜草科（Rubiaceae）植物，为二裂花。实验授粉表明，这两种变体是自交亲和。然而，thrum变体被证明是更自我兼容。相同花型的不同植物之间的手异花授粉比针和线头或线头和针授粉之间的手异花授粉产生更少的种子集每次授粉。传粉昆虫主要有蜂科和海象科两种，双翅目食蚜蝇科两种。
Hedyotis salzmannii (Rubiaceae) is distylous. Experimental pollination revealed that both morphs are self-compatible. However, the thrum morph proved to be more self-compatible. Hand cross-pollination between different plants of the same floral form produced less seed-sets per pollination than hand cross-pollination between pin and thrum or thrum and pin pollination. Two species of Hymenoptera, one Apidae and one Halictidae, and two species of Diptera (Syrphidae) were observed as pollinators.
