rootstocks, narrow linear or 'sometimes oblong or lanceolate sheathing 
basal or rarely cauline leaves, and white, pink, or purple flowers in a 
terminal umbel which is subtended by 2 or 3 membranous bracts. Scape

ments filiform or dilated, occasionally toothed; anther-sacs ihtrorsely 
dehiscent. Ovary sessile or nearly so. 3-celled or partially so; style fili- 
form, jointed, usually deciduous; stigmas small; ovules 1 — G in each cell.

1. Allium tiucocc'Um Alton, Hort. Kew. 1: 428. 1789. Wild Leek. 
Rootstock short; rootlets many, slender; bulbs usually clustered, ovoid, 
1 — 2 inches high, with fibrous reticulated coats; leaves 2 or 3, appearing 
in April and May, soon withering, oblong-lanceolate or elliptic, acute or 
acuminate, base tapering to long petioles, thin, blades 5 — 12 inches long, 
1 — 3 inches wide, bases of petioles sheathing; scapes 5 — 14 inches high; 
bracts usually 2. at first enfolding the umbel, membranous, acuminate 
deciduous;’ flowers 10 — 30, erect, appearing in June and July; pedicels 
slender, thickened in fruit, 6 — 10 lines long; fiowers white; perianth- 
segments oblong, obtuse, 2 — 3 lines long; filaments lanceolate-subulate, 
about equaling the perianth; ovary 3-celled. with one ovule in each cell; 
capsule deeply 3-lobed, 2 lines or less in height. 3 lines broad; seeds glo- 
bose, smooth, black. 
This species occurs in rich woods from New Brunswick to Minne- 
sota, south to North Carolina, Tennessee and Missouri. The plants some- 
times occur singly, but usually clustered into a considerable bed. In 
Iowa the species is frequently met with in the eastern portion of the 
state, but becomes rarer northward and westward.
