Plant Bio

Azolla microphylla is a tropical and subtropical fern with a length of 1.5-2.5 cm. Some genera can grow in brackish waters, but these biota are more commonly referred to as freshwater plants.

These aquatic ferns have slender, branched stems with bilobed leaves that resemble the leaves of cedars. As with other ferns, reproduction occurs through the production of spores, but the plant may spread very rapidly because the stems also break easily and each fragment becomes a new plant. These plants can double their weight in just a few days. A population may proliferate into a mat of floating plants, so sometimes it is called “duckweed fern.”
