Schoenoplectiella juncoides

Schoenoplectiella juncoides is a sedge (a member of the Cyperaceae family), native to east Asia and Oceania. It is a serious weed of rice paddies. S. juncoides, also known as Kaluha or rock bulrush, belong to the Cyperaceae family. It is indigenous to Hawai‘i but is also native to Madagascar and North America. Kaluha is not like the average flower species, as it does not grow bright, scented flowers. Instead, it grows tall leaves with spiky flowers annually. This species may improve this environment in ways such as preventing erosion and providing a habitat for some species. In other environments such as rice fields, it is considered invasive and could reduce crop yields. This sedge was first described by William Roxburgh as Scirpus junc(e)oides in 1814, in 1888, Eduard Palla transferred it to the genus Schoenoplectus and the accepted name was Schoenoplectus juncoides for many years. In 2003, it was transferred to the new genus Schoenoplectiella by Kåre Arnstein Lye. It was discovered ......read more on Wikipedia.
