Cyperus aromaticus
Cyperus aromaticus, the aromatic kyllinga, is a perennial plant with triangular stems and aromatic leaves, native to tropical Africa. It is also found as an introduced species in parts of Asia and Australia. The plant grows in wet, moist areas and is characterized by a flowering head that forms a tuft of spikelets. It was first formally described in 1884 by Henry Nicholas Ridley.
