Blyixa japonica is a species of plant in the family Hydrocharitaceae.[3] It is known as Japanese blyxa or dwarf Asian grass.[4]

Description[edit | edit source]

The flowers are bisexual, actinomorphic and have numerous ovules. It has whorled leaves.[5] It can be told from the genus Limnobium by its pollen, which has spine-like projections.[6]

Distribution[edit | edit source]

The species is native to China, Taiwan, Japan, and Papua New Guinea.[7] It has naturalized in Italy. In the wild, the species is found in shallow, stagnant water such as rice paddies.[4]

Cultivation[edit | edit source]

The species, along with other members of the genus such as Blyxa aubertii, are common in the aquarium trade. B. japonica is difficult and demanding to grow.[4]

B. japonica var. japonica, B. j. var. alternifolia, and B. j. var. recurvifolia are all found in cultivation.[4]
