TAXONOMY NYMPHAEA ODORATA. 179 



In all of these varieties, both larger and smaller forms occur. This division has 

 been adopted by some botanists, but is decidedly too cumbrous for practical use. We 

 have therefore inserted the most important variety and the only one requiring special 

 notice, namely, the pink Swedish waterlily, under its usual name, Nyinphaea alba var. 

 r libra. 



Var. rubra, Lonnrotli. (Plate XV.) 



Outermost petals rosy, intermediate intensely rosy, innermost deep carmine-red ; 

 anthers and stigma yellow ; filaments and styles orange to deep red-brown. Variable in 

 depth and purity of color, deepening on second and third days of flowering.

N. sphaerocarfa var. rubra, Duchartre 1877. 



N. Caspary, Carriere 18796 (AT. Caspari Carriere 1880; N. Casparyi Carriere 1888). 



DESCRIPTION. Flowers 7 to 15 cm. in diameter, opening pale pink, changing to 

 rose-pink or even deep red, often with a bluish cast; the color appears as linings on 

 a white or pink ground. Petals narrower than in the type, obtuse or rounded. 

 Rhizomes strong, branching as in the type. 



GEOGRAPHIC DISTRIBUTION. Lake Payer (Fagertarn) in the Parish of Hammar, 

 Nerike, Sweden, collected by B. E. Kjellmark in July, 1856. 



NOTES. Introduced by Caspary in 1871 and later by Froebel of Zurich, and sold 

 in England in 1878 at 5 per root. Requires cool weather and water, and is difficult of 

 cultivation, at least in this country. Flowered first in America by Mr. Hovey of Bos- 

 ton, and later by Wm. Tricker at Dongan Hills, N. J. It was received by Caspary in 

 1863, and in the Botanic Garden of Konigsberg was found to produce highly fertile 

 crosses with the type (N. alba sphaerocarpa) ; a close relationship was thus proven. 



E. Fries, in a letter to the " Botanische Zeitung," published in 1858 (p. 73), 

 refers to this as a Nymphaea with rosy-purple flowers, giving to its native pond in 

 Nerike, the name of " Fagersjo," " the beautiful lake." He considered it only a form 

 of N. alba. 



Carriere writes in 1888 of a N. casparyi alba, as a new seedling from N. casparyi; 

 the description is peculiar; but if it refers to a white form, it can be no less than a 

 return to the typical color. 



Nymphaea odorata Ait. (Fig. 67.) 



Rhizome horizontal, with few stout persistent branches. Phyllotaxy about 2 on 

 5, with long internodes (2 to 5 cm.). Petioles even greenish- pur pie. Leaves orbicu- 

 lar, usually purplish beneath, coriaceous; sinus open or closed. Flower very sweet
