Chara (Stonewort)
Chara sp.
Plantae›Charophyta›Charophyceae›Characeae
📍 Worldwide in clear, hard freshwater lakes
Not a true alga but a charophyte — an evolutionary stepping stone between algae and land plants. Whorled branches on brittle stems; produces a distinctive musky smell when crushed. Tolerates very hard, alkaline water that many plants cannot. Often kept deliberately in biotope setups for its unique look.
