92 NATURAL HISTORY OF FLANTS. 



distinct orders : Nymphaacea, Cabombea of L. C. Kichard, 1 and 

 Ndumbonece: 2 At the present day Bentham.& Hooker 3 consider these 

 three groups as onty tribes of the single order Nympltaacece, and 

 place them next to Sarracena cea, and distinct from it, herein following 

 De Candolle and Lindley. 4 A. L. de Jussieu left Sarracena in his 

 Genera insertce sedis* but Endicher considered it a sort of appendage 

 to Nymphteacece* linking this order with Cabombea;, and we have 

 followed his example, making, not without some hesitation, the 

 SarracenecB into a fourth somewhat abnormal series of the order 

 Nymphaacea. Of this order, thus limited, Tournefort made the 

 genus Nelumbo in 1700 ; Linnaeus knew the two genera Nympliaa 

 and Sarracena. The genus Cabomba was made in 1775 by Aublet, 

 Brasenia, in 1789, by Schreber. 7 In the early part of this century 

 Euryale was proposed by Salisbury, 8 and Nuphar by Smith 9 in the 

 same year, 1806. Wallich described Barclaya in 1826, and 

 Bentham published Heliamphora as a near relation of Sarracena in 

 1838. Torrey has recently made known Darlinytonia, another 

 member of the same small group. According to our views the 

 order Nymph aacece will thus comprise ten genera, including two- 

 score species. The eight species of the series Sarracenea are all 

 American. 10 So is Cabomba ; but Brasenia pel fata is found in fresh 

 water in most parts of the tropics. Nelumbo and Euryale each one 

 species from either hemisphere. The two Bar clay as are Malaysian. 

 The two dozen species of Nymphcea and Nnpltar are to be found in 

 all parts of the globe from the south of Asia and South America right 

 up to Siberia, Swedish Lapland, and the Hebrides and Shetlands, 

 thus spreading over a zone of 110° of latitude. 



The affinities are as variable as the structure in this order. By the 

 sjmcarpic types, like the Sarracenece and Nymp/ta'acea, it approaches
