Popis:	The combined effects of elevated atmospheric CO2 and nutrient supply rate on plant biomass accumulation were determined for four Leucadendron species (Proteaceae) of the mediterranean climate Fynbos Biome, South Africa. Juvenile individuals were grown for 6 months in experiments comprising 2 X 2 factorial combinations of substrate nutrient supply rate and atmospheric CO2 concentration in open-top chambers in a greenhouse. The four selected Leucadendron species included one pair of species common on extremely nutrientpoor acid sands (typical of the Fynbos Biome), and another pair associated with more nutrient rich substrates (rare in the Fynbos Biome). Plant biomass accumulation data were
