Caption

A small savannah on shallow rock sands surrounded by rainforest near Libreville, Gabon, tropical Africa. In the foreground all grasses are parasitised by a still unidentified species of Cassytha, ranking as 'Black Star'. The researchers identify four standardised 'Star' categories of global rarity. Black Star species are the world's rarest plant species, known from only a few localities worldwide.
