178 THE WATERULIES. 



panied by leaves of the usual size ; it was collected at two stations near Lich. All of 

 these were supported by numbers of specimens in all stages of flower and fruit. 



In Greece, N. aesopii of Macedonia was separated off by Orphanides on account 

 of its huge size, and TV. dioscoridis from Lake Lysimachia in Aetolia for its smallness. 

 Caspary began his work on waterlilies by reviewing this species. He rightly 

 maintained that the smallness or largeness of the plant is not a safe guide to classifica- 

 tion, but that there were other characteristics of a more profound and constant nature 

 on which divisions could be founded. Accordingly in 1855 he gave the following 

 arrangement : 



N. alba. 



I. melocarfa. 



A. dcpressa. 



a. chlorocarpa ==N. venusta Htze. 



= N. rotundifolia Htze. 



b. crytlirocarpa = N. erythrocarpa Htze. 



B. circumvallata. 



C. sphaerocarpa. 



a. chlorocarpa. 



a. flava =N. parviflora Htze. 



= N. alba Htze. 

 ft. splcndens = N. splendens Htze. 



b. erythrocarpa. 



D. urceolata = N. urceolata Htze. 



II. Oocarpa (see under N. Candida Presl). 



In 1863 Caspary changed the main headings, substituting I. Polystigma and II. 

 Oligostigma in the above table. Finally in 1879, as referred to under N. Candida, he 

 raised the two varieties to specific rank under the names of N. alba (L.) Presl and 

 N. Candida Presl, dividing the former species and giving a few localities, thus : 



N. alba. 



I. sphaerocarfa. Fruit subglobose. 



1. platystigma. Stigma more than half the diameter of the fruit (commonest form). 



A. chlorocarpa. Fruit green (widely distributed). 



a. flava. Stamens sulphur color. 



b. splendens. Stamens orange. 



B. erythrocarpa. Fruit more or less suffused crimson. 



a. I'ulgaris. Petals white, or outer ones pale rosy. 



b. rosea. Petals and stamens deep crimson = N. alba and rosca Hartm. Handb. 



Skand. Fl., 1864, p. 76. 



2. cngystigma. Stigma, measured from the backs of the processes, equal to or less than 



half the diameter of the fruit (rare) ; West Prussia, near Danzig. 



II. deprcssa. Fruit depressed-globose; alt. : lat. = 2:3 to 5: 6. 



1. chlorocarpa here and there in Germany. 



2. erythrocarpa here and there in Germany. 



III. urceolata. Stigma deeply infundibuliform in fruit, sunk in to middle of fruit in Ger- 



many, very rare. Chlorocarpa and erythrocarpa. 



IV. ovlformis. Fruit ovoid; upper one-fourth to one-third of height destitute of filaments in 



some lakes of West Prussia.
