I \ility. Banks of the Upper and Lower Avon, by the sides of

 2, 3, 4, 5. General!// distributed in the count)/. Floivers handsome, 3 

 in ouch whorl, with combined egg-spear-shaped bracteas at the base of 

 their partial stalks. Petals white with a purplish tinge at the claws, 

 soon falling off. Leaves all from the root, on long, triangular, very 

 cellular footstalks, the first which are always under water, long and 

 strap-shaped, by some authors considered as a variety, and well 

 figured in Flora Danica, t. 172, the succeeding, which rise above the 

 water, larg-e, truly arrow-shaped, very entire, smooth, with parallel 

 ribs and reticulated veins. Nothing is more variable than the 

 breadth and size of the leaves, which are diminished almost to nothing 

 when deeply immersed in the water, or exposed to a rapid current. 

 Hence several varieties are mentioned by authors, but the slightest 

 observation will discover them to be evanescent.
