YELLOW 



[PI. LXIX 



Steironema ciliattim. Primrose Family. 



Stem. Erect ; two to four feet high. Leaves. Opposite ; narrowly 

 oval ; on fringed leaf-stalks. Flowers. Yellow ; on slender stalks from the 

 axils of the leaves. Calyx. Deeply five-parted. Corolla. Deeply five- 

 lobed ; wheel-shaped ; yellow, with a reddish centre. Stamens. Five. 

 Pistil. One. 



This plant is nearly akin to the yellow loosestrifes, but un- 

 fortunately it has no English name. It abounds in low grounds 

 and thickets, putting forth its bright wheel-shaped blossoms early 

 in July. 



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. 



PRICKLY PEAR. INDIAN FIG. 



Opuntia Rafinesquii. Cactus Family.

 across. Calyx. Of numerous sepals. Corolla. Of ten or twelve petals. 

 Stamens. Numerous. Pistil. One, with numerous stigmas. Fruit. 

 Shaped liked a small pear ; often with prickles over its surface. 



This curious looking plant is one of the only two representa- 

 tives of the Cactus family in the Northeastern States. It has
