nutritious food ; in such a pursuit many of the otherwise unat- 

 tractive popular names would prove suggestive. 



COMMON BLADDERWORT. 



Utricularia vulgaris. Bladderwort Family. 



Stems. Immersed, one to three feet long. Leaves. Many-parted, 

 hair-like, bearing numerous bladders. Scape. Six to twelve inches long. 

 Flowers. Yellow, five to twelve on each scape. Calyx. Two-lipped. 

 Corolla. Two-lipped, spurred at the base. Stamens. Two. Pistil. 

 One. 



This curious water-plant may or may not have roots ; in 

 either case it is not fastened to the ground, but is floated by 

 means of the many bladders which are borne on its finely 

 dissected leaves. It is commonly found in ponds and slow 

 streams, flowering throughout the summer. Thoreau calls it " a 

 dirty-conditioned flower, like a sluttish woman with a gaudy 

 yellow bonnet." 



The horned bladderwort, U. cornuta, roots in the peat-bogs 

 and sandy swamps. Its large yellow helmet-shaped flowers are 

 very fragrant, less than half a dozen being borne on each scape. 



YELLOW POND-LILY. SPATTER DOCK. 



Nuphar advena. Water-lily Family. 



Leaves. Floating or erect, roundish to oblong, with a deep cleft at their 

 base. Flowers. Yellow, sometimes purplish, large, somewhat globular. 

 Calyx. Of five or six sepals or more, yellow or green without. Corolla. 

 Of numerous small, thick, fleshy petals which are shorter than the stamens 

 and resemble them. Stamens. Very numerous. Pistil. One, with a 

 disk-like, many-rayed stigma. 



Bordering the slow streams and stagnant ponds from May 

 till August may be seen the yellow pond-lilies. These flowers 

 lack the delicate beauty and fragrance of the white water-lilies ; 

 having, indeed, either from their odor, or appearance, or the form 

 of their fruit, won for themselves in England the unpoetic title 

 of " brandy-bottle." Owing to their love of mud they have 

 also been called < ' frog-lilies. ' ' The Indians used their roots 

 for food.
