A new species of Ochna (Ochnaceae) from the Barberton Mountains of Mpumalanga, South Africa.
Ochna barbertonensis is described as a new species from the Barberton Mountains in Mpumalanga, South Africa. The new species is characterised by its suffrutescent habit, elongate-deltoid stipules sometimes with broadened base, mucronate leaf tip and high anther to filament ratio, where the anthers are ca. two times longer than the... -

Metal‐rich soils increase tropical tree stoichiometric distinctiveness
Background and aims Ultramafic soils have high metal concentrations, offering a key opportunity to understand if such metals are strong predictors of leaf stoichiometry. This is particularly relevant for tropical forests where large knowledge gaps exist. Methods On the tropical island of Sulawesi, Indonesia, we sampled forests on sand, limestone,... -

Floristics of forests across low nutrient soils in Sulawesi, Indonesia.
The island of Sulawesi formed from the joining of proto‐islands roughly three million years ago. Regions of zoological endemism, corresponding to the proto‐islands, have been reported. Sulawesi's tree communities, however, remain poorly documented. In better‐studied tropical regions, soil types similar to those found in Sulawesi often have distinctive tree communities....
