St Helena ebony (Trochetiopsis ebenus) flower with secondary pollen presentation, endemic to St Helena, critically endangered

---

St Helena ebony (Trochetiopsis ebenus) critically endangered in the wild. A related species the dwarf ebony (Trochetiopsis melanoxylon) is now completely extinct, last recorded by Banks in 1771. Example of secondary pollen presentation. The pollen-producing anthers split open while the flower is still in bud. This has the effect of depositing some pollen on the top edges of the petals. Pollinators visiting the flower are nearly certain to brush against the petal-borne pollen and thereby increase cross-pollination. fromDaniel Mosquin explanation:
