Leibergi.) It is a diminutive plant, said to resemble pygmœa (telragona), but with obtuse 

 petals, which are described as faintly striped with purple lines (as in elegans), but the 

 figure shows the leaf to be more elongated than in either of these species. The rhizome 

 and seeds have not been seen. Its trvie relations remain to be ascertained.

 Leitner in Audubon's Birds, p. 411, (1838)." The Garden XXIII, p. 331, with coloured 

 j)late ; also XXVII, (1885, pp. 439 and 599). I cannot verify the reference to Leitner. 

 There is no allusion to a Water Lily in the original edition of Audubon's Ornithological 

 Biography, published at Edinburgh in 1831, nor any reference either to Leitner or 

 Nymphœa Jiava in Pritzel's works, the Thesaurus Lit. Botanicse or the Iconum Botanic- 

 arum Index.

 Water Lily of Florida. 



This species is described as having flowered in the Harvard Botanic Garden in the 

 spring- of 18*78, and in England in 1881. The drawings in " The Garden, prepared from 

 plants that flowered at Kew, in August 1882," show the erect rootstock, covered with 

 scale-like nodules, the young sagittate submerged leaves, and mature floating ones ; also 

 the lateral annual runners or stolons, which are thrown out, each ending in a permanent 

 bud bearing leaves and flowers and forming a new plant. The flowers are lemon-yellow, 

 an exceptional colour in this genus. Although described and named in botanical works 

 only a few years ago, this plant is Hgured in Audubon's Birds of America. Mr. Frank 

 Miles, writing in The Garden, (XXVIII, p. 053, Dec. 26, 1885), finds it hardy at Bristol, 

 and says it has flowered in a pond in Kent. He speaks of it (from a cultivator's point of 

 view, I presume) as the same, " or nearly so," as Amazonica.

Native of Australia. Flowered in Van Houtte's nurseries, Paris, in 1855, and at Kew, 

 where materials for the illustration in The Garden were obtained. The tubers are 

 described as long and thick, with eyes scattered OAan- their surface like those of potatoes. 

 " There are three forms at Kew, — one [with flowers] a clear blue, another paler, and a third 

 almost white," Flowers usually blue, but A^arying with white, rose and i)urple colours.
