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.

 the filaments. Style 3-cleft. Pod 3-lobed, 3-celled, few-seeded. 



1. U. perfoliata L. 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 two-thirds the size of the preceding. 



2. U. grandiflora Sm. 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, H in. 

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



V. OAKESIA Wats. 



Plants with much the aspect of the preceding genus, but 

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

 der, creeping rootstocks. 



1. 0. sessilifolia Wats. WILD OATS, STRAW LILIES. Stem slen- 

 der, zigzag. Leaves lance-oval, thin, smooth, pale beneath, 1-1 in. 

 long. Flower cream color, nearly 1 in. long. 



VI. ALLIUM L. 



Herbs appearing stemless from coated bulbs with the 

 characteristic odor of onions. Bulbs solitary or clustered. 

 Leaves narrowly linear or slender-tubular, with a bloom. 

 Flowers small, on slender pedicels, in terminal umbels on 

 naked scapes, the umbels often bracted or inclosed in a 

 spathe. Perianth 6-parted, persistent ; stamens 6, somewhat 

 perigynous, filaments filiform or dilated below. Ovary sessile, 

 3-celled; style thread-like, jointed; stigma entire. Fruit a 

 3-celled, 3-valved, few-seeded capsule. Flowers sometimes 

 changed into bulblets.* 



1. A. reticulatum Don. Resembling A. Nuttallii, but with larger 

 bulbs. Leaves narrowly linear. Scape slender; bracts usually 2, taper- 

 pointed; pedicels slender, |-| in. long. Flowers white or pink; seg- 

 ments of the perianth thin. Capsule crested. W. 



2. A. Nuttallii Wats. Bulbs ovoid, their coats with a fibrous net-
