Spring Beauty. 



Calyx herbaceous, of two ovate sepals, imbricated in aes- 

 tivation (both margins of one exterior), persistent. Petals 

 5, hypogynous, equal, quincuncially imbricated in aestiva- 

 tion, distinct, or somewhat united by the short claws or con- 

 tracted base, spreading, expanding for more than one day, at 

 length gelatinous-colliquescent. Stamens 5, equal, one be- 

 fore each petal ; the filiform or subulate filament inserted 

 on its base : anthers oval or oblong, fixed by the middle, 

 introrse ; the cells opening longitudinally. Ovary ovoid, 

 one-celled: style slender, three-cleft ; the slender divisions 

 stigmatose down the inner side. Ovules 3 to 6, on short 

 free funiculi which rise from the base of the cell, campy- 

 lotropous. 



Capsule ovoid, membranaceous, one-celled, three-valved 

 (loculicidally) 3-6-seeded from the base. Seeds erect, len- 

 ticular, with a shining crustaceous testa, not strophiolate at 

 the hilum. Embryo incompletely annular or curved into 

 the form of a horseshoe around the outside of the farina- 

 ceous albumen : radicle inferior, much longer than the 

 semiterete cotyledons.
