OEDEE VIII. ISTympliceaceae. Water-Lily- 

 family. 



1. NYMPH<EA. 



Sepals 4 5. Petals and stamens indefinite in number, in- 

 sensibly passing into each other. Stigma surrounded by rays. 

 Pericarp many-celled, many-seeded. Per. 



1. N. odorata. White Pond-lily. 



Leaves orbicular, cordate at base, entire, smooth, with prominent veins be- 

 neath, dark green above, paler beneath, always floating on the surface ; petioles 

 semi-cylindrical, very long in deep water ; sepals 4, equalling the petals, which 

 are lanceolate, white, often tinged with purple ; filaments yellow. This truly 

 beautiful flower, which claims superiority over all our water plants, for com- 

 bined elegance and fragrance, is common in deep ponds, and slow-moving 

 rivers, where its thick, fleshy, creeping rhizomas are protected from the winter 

 cold. July. 



2. NtTPHAE. 



Sepals 5 6, somewhat petaloid. Petals numerous, inserted 

 with the sepals, much smaller, nectariferous on the back. Sta- 

 mens linear, truncate, inserted with the petals. Stigma sur- 

 rounded with rays. Per. 



1. N. ad vena. 



Yellow Pond-lily. 



Leaves oval, smooth, entire, cordate at base, with an open sinus, on long, 

 semi-terete, spongy petioles ; flowers large, dull yellow ; sepals 6, 3 outer yel- 

 low inside, 3 inner entirely yellow ; petals many ; stigma 12 15-rayed, with a 

 crenate margin. A rather handsome plant, growing in muddy ponds, and stag- 

 nant waters. The leaves are slimy beneath, and He flat on the surface, when 

 the water is deep, but are larger and erect where it is shallow. June July. 



OEDEE IX. 



Sarraceniaceae. Pitcher^plant- 

 family. . 



/ t7 



1. 8AEEACENIA. 



Sepals 5, with an involucre of 3 bracts at base. Petals 5, de- 

 ciduous. Stigma very large, peltate, 5-angled, persistent. Cap- 

 sule 5-celled, 5-valved, many-seeded. Per. 



1. S, purptkrea. Pitcher Plant, Side-saddle flower. 



Leaves radical, decumbent, with tubular, inflated, gibbous petioles, which 

 are winged on the inside, i. e. pitcher-form, ending in a broadly cordate, erect 

 lamina, which is hairy on the inside, and makes the mouth of the pitcher. This 

 process, though small compared with the tubular portion, is yet the real leaf of 

 the plant Scapes 12' 20' high, with a single, large, nodding, dark-purple 

 flower; petals inflected over the stigma. This plant, which is one of the most 

 remarkable of our native species, is not uncommon in wet meadows, where its 

 curious flowers, and still more curious leaves, attract the attention at once of 

 even the common observer. The pitchers are almost filled with water, contain- 

 ing drowned insects. June.
