 L. (shore-weed) in Eur. (incl. Brit.). This pi. exhibits two forms, 

 one in water, another on land. The land form has a rosette of 

 narrow 1. about 3 cm. long, which spread out upon the ground and 

 show distinct dorsiventral structure. Fls. in groups of 3, one cf on a 

 long stalk between two sessile , which are ripe before the sta. emerge 

 from the former. Both sta. and style are very long and the fls. are 

 wind-pollinated. Fr. a nut. The water form has much larger 1. 

 which grow erect and are cylindrical (centric) in form and internal 

 structure; no fls. are produced, but the plant multiplies largely by 

 runners. It is often mistaken for Isoetes.
