Lehm. in hb. Berlin. 



Notes. Hooker & Thomson record, and the herbaria bear them out, that no 

 sharp line could be drawn between the varieties of this species as it occurs in India, 

 but they were certainly wrong in including the African plants. The three extreme 

 Indian forms are themselves fairly recognizable. The margin of the leaf may be al- 

 most entire. The pustules so evident on the leaf of our N. versicolor cultivated from 

 seeds sent by Mr. Gollan of Saharanpur, India, may be present at times in the other 

 varieties. Our plant also had a great number of bulbils on the caudex, as shown in 

 several herbarium specimens both of blue and pink forms. 



Willdenow's description was based solely on the figure and text of Van Rheede's 

 Flora Malabarica 1 1 : 53, tab. 27, and was very brief : " N. foliis integerrimis, lobis 

 divaricatis, acutis, calyce tetraphyllo petalis acutis longiore." Andrews figured the plant 

 in color and later Sims gave a rather larger form than that of Andrews. Planchon figures 

 a plant evidently identical with that of Andrews and Van Rheede, and Caspary (1877) 

 places its description clearly in parallel columns with the allied forms N. caerulea, 

 capensis, and zanzibariensis. Of these it comes much nearest to N. caerulea, but is 

 plainly distinct. I have been unable to find it in American gardens. 



The flowers of this species, according to Caspary (1877), are regularly self-polli- 

 nated, often while still in the bud ; it refused to cross with N. caerulea under Caspary's 

 management. 



Rose-colored and white varieties of N. stellata sent from Canara to Caspary by the 

 missionary Zeigler in 1869 were long cultivated in the botanic garden at Konigsberg. 



Nymphaea caerulea Savigny. (Plate VIII; Fig. 55.) 



Leaves entire or slightly wavy at base, orbicular or ovate-orbicular, narrowly 

 peltate, becoming 30 to 40 cm. in diameter; green above; under surface green with 

 small dark purple spots, purplish all round near margin. Flowers 7 to 15 cm. across, 

 open from 7.30 a. m. to 12 m. Buds conical. Sepals thickly marked with black lines 

 and dots. Petals 14 to 20, lanceolate, light blue above, lower half dull white. Stamens 

 50 to 73; appendage long (0.5 cm. on outermost stamens), slender, pale blue.
