Azolla pinnata (mosquito fern; Ferny azolla; Water velvet; feathered mosquitofern)

Wikipedia Abstract

Azolla pinnata is a species of fern known by several common names, including feathered mosquitofern and water velvet. It is native to much of Africa, Asia from China to Japan, India, Brunei Darussalam and the Philippines, and parts of Australia. It is an aquatic plant, its frond floating upon the surface of the water. It grows in quiet and slow-moving water bodies, because swift currents and waves break up the plant. The plant reproduces vegetatively when branches break off the main axis, or sexually when sporocarps on the leaves release spores.

Invasive Species

Azolla pinnata can spread rapidly, and has the ability to survive on moist soil in and around rivers, ditches, and ponds. It forms dense surface mats, which degrade water quality by reducing oxygen levels, and can interfere with boating, fishing and recreational activities.
