a. (P. bifloeum), Smaller Solomon's Seal. Leaves minutely 

 hairy underneath ; stem slender, 1-3 ft. high ; most of the peduncles 

 2-flowered.

 stout and 2-7 ft. high ; peduncles 2-8-flowered. 



II. UVULARIA, BELLWORT. 



Flowers yellow or yellowish, drooping, borne singly at the 

 end of the forking stem. Perianth of 6 similar and separate 

 narrow spatulate sepals, each grooved and nectar-bearing 

 inside toward the base. Stamens 6, with linear anthers, 

 which are much longer than the filaments. Style 3-cleft. 

 Pod 3-lobed, 3-celled, few-seeded. Leaves alternate, broad 

 and parallel-veined. Eootstocks short. 



a. (U. GRANDiFLORA), LARGER Bellwort. Leaves oblong, with 

 the base clasping the stem so as to make it appear to run through 

 the leaf a little way from the base ; flowers greenish yellow, 1^ in. 

 long, anthers obtuse. A leafy plant, 1-2 ft. high. 



b. (U. perfoliata). Mealy Bellwort. Leaves much as in the 

 preceding species ; flowers very pale yellow, with shining grains on 

 the inner surfaces of the twisted sepals ; anthers sharp-pointed ; 

 plant about f the size of the preceding. 



in. OAKESIA, WILD OATS. 



Plants with much the aspect of the preceding genus, but 

 with merely sessile leaves, triangular winged pods, and slen- 

 der creeping rootstocks. 



(O. sessilifolia), Wild Oats, Straw Lilies. Leaves lance- 

 oval, thin, smooth, pale beneath, 1-1 J in. long ; flower cream-color, 

 nearly 1 in. long. 



IV. ERYTHRONIUM, DOG-TOOTH VIOLET. 



Perianth open bell-shaped, of six parts, with the tips 

 recurved. Stamens 6, with flat awl-shaped filaments and 

 erect anthers. Style rather long. Capsule obovate. No 

 stem apparent above ground. Leaves two, long and smooth, 

 tapering into petioles which arise from a pretty deeply buried 

 bulb. The (commonly) single, nodding flower is borne on a 

 long peduncle (scape), which arises from between the bases of 

 the leaves.
