''Lemna trisulca'' L. (syn. ''Staurogeton trisulcus'' (L.) Schur; star duckweed; ivy duckweed) is a species of aquatic plants in the genus ''Lemna'' (duckweed) with a subcosmopolitan distribution, occurring in quiet freshwater habitats in cool temperate regions. ''L. trisulca'' normally doesn't occur in warm temperate regions. Unlike other duckweeds, it has submersed rather than floating fronds, except when flowering or fruiting. ==Description== The leaves usually grow submerged and are oblong-lanceolate in shape and are up to 14mm long. They are blunt at the end and taper to a tail-like stalk at the other.〔Parnell, J. and Curtis, T. 2012. ''Webb's An Irish Flora.'' Cork University Press. ISBN 978-185918-4783〕
