SO On the Management of Aquatic Plants. 



of Good Hope ; perhaps the most desirable of the whole 

 genus, being a plant more easily cultivated, than others of the 

 tender species ; bearing several flowers at a time, in constant 

 succession, of a fine sky-blue colour, which are very fragrant, 

 commencing to bloom early in the season, and continuing 

 when most of the others have ceased ; leaves slightly dentate, 

 of a pale green ; flowers most part of the year. Introduced 

 in 1792, and is figured in the Botanical Magazine, Plate 552, 

 and in Andrews's Repository, Plate 197. 



12. Nymphcea stellata : a native of the East Indies] with 

 entire smooth leaves, and blue flowers, but not so large or of 

 as fine a colour, and scent, as the last ; neither are the petals 

 so numerous ; flowers through the summer. Introduced in 

 1803, and is figured in Andrews's Repository, Plate 330. 



The first five species oiNymphceas may be deemed hardy, 

 having lived, through several winters, in the pond, in my gar- 

 den ; but N. pygmcea flowers best, when treated more tenderly. 

 It is worthy of notice, that the flowers of those, which are 

 hardy, float on the w&ter ; while those of the tender ones, which 

 are the remaining seven, are elevated several inches above it. 



The third genus has four species ; these formerly made 

 part of the genus Nymphcea, but are now separated under 

 the new denomination of Nuphar. 



1. Nuphar lutea : a native of Britain ; growing in rivers 

 which are from three to ten feet deep ; with ovate floating, 

 lobed, leaves ; the flowers yellow, buoyant on the surface of 

 the water, and blossoming through the summer months. Figu- 

 red in English Botany, Plate 159, as Nymphcea lutea. 



2. Nuphar minima : growing upon Ivy Moor, in Perth- 

 shire, in a shallow pond, amongst decayed leaves ; has much 

 the habit of the former, but is decidedly distinct, and of
