- Bacopa amplexicaulis — The scientific name of a perennial aquatic plant species in the genus Bacopa, characterized by erect stems and fleshy, ovate leaves that partially clasp the stem (amplexicaul). Also known by its synonym Bacopa caroliniana, this structural plant is highly popular in the aquarium hobby due to the aromatic lemon scent emitted by crushed leaves and its high resilience in intensely lit tanks.
