Common Name
Tweedie's pearlweed, Montecarlo pearlweed, New Large Pearl Grass, Bacopita
Description
A highly interesting and recommendable ground-covering plant that was a rarity few years ago but got very popular in the aquascaping. It was discovered for the aquarium hobby around 2010 by Japanese and also South American aquarists. It was called Micranthemum sp. "Montecarlo-3" or "Monte Carlo" after a locality in the Argentinian province Misiones, as well as "New Large Pearl Grass" and "Bacopita". The plant has been identified as Micranthemum tweediei in the meantime. This Micranthemum occurs in Argentina, Uruguay and South Brazil, in wet places such as streambanks. It looks like a larger version of Hemianthus callitrichoides, growing flat on the ground, forming a compact mat, in the emersed and submerged form. Its roundish to elliptic leaves are a bit smaller and of a darker green than those of the similar Micranthemum umbrosum.
