AB  - Pollination biology studies of the endangered herbal medicines <i>Dendrobium chrysotoxum</i> were conducted in natural pollination conditions using flower observation, pollinator observation and artificial pollination experiments. Populations of <i>D. chrysotoxum</i> with fragrance and nectar were pollinated by <i>Ctenoplectra davidi</i> Valhalla (Hymenoptera: Apidae) species. The floral structure of <i>D. chrysotoxum</i> adapted precisely to its pollinators. Flowers had a low capsule setting (0.17%) under natural conditions. However, compared to open pollination, artificial pollination experiments showed a significant increase in capsule setting, and <i>D. chrysotoxum</i> was cross-compatible and self-compatible, but there was pollinator limitation also. This study will provide important information for the preservation of this endangered species.
