Two endemic species of the same flowering plant — O nakaiana and O hexandra — have distinctly different origins. Their study is based on molecular analysis of chloroplast samples of this genus taken from surrounding areas. The study demonstrates the complexity of floral speciation and distribution.

Tree beta diversity — a measure of site-to-site variation in the composition of species present within a given area — matters more for ecosystem functioning than other components of biodiversity at larger scales. The finding has implications for conservation planning.
