3. ALLIUM L. Sp. PI. 294. 1753. 



Bulbous herbs, odorous (alliaceous) ; bulbs solitary, or clustered on short rootstocks. 

 Leaves narrowly linear, rarely lanceolate or oblong, sheathing, basal, or sometimes also on 

 the stem. Stem (usually a scape) simple, erect. Flowers white, purple, pink or green, in a 

 terminal simple umbel, subtended by 2 or 3 membranous separate or united bracts. Pedicels 

 slender, not jointed. Perianth persistent; segments 6, separate, or united by their bases. 

 Stamens on the bases of the perianth-segments; filaments sometimes toothed; anther-sacs 

 introrsely dehiscent. Ovary nearly sessile, 3-celled; style filiform, jointed, deciduous; stigmas 

 small; ovules 1-6 in each cavity. Capsule loculicidal. [Latin for garlic] 



About 300 species of wide distribution. Besides the following, some 50 others occur in the 

 western United States. Type species : Allium sativum L.

Bulb-coats membranous, not fibrous-reticulated. 



Umbel capitate ; pedicels shorter than the flowers. 

 Umbel loose ; pedicels much longer than the flowers. 

 Flowering umbel nodding. 



Perianth campanulate, white or pink, its outer segments acute. 3. 

 Perianth urn-shaped, purple, outer segments obtuse or notched. 4.

Bulbs ovoid, clustered, i'-2' high, seated on a 

 short rootstock, their coats fibrous-reticulated. 

 Leaves oblong-lanceolate or elliptic, appearing early 

 in the spring, but withering before flowering time, 

 6'-i2' long, 1/-2' wide, narrowed at both ends, 

 tapering into a long petiole ; scape 4-15' tall ; bracts 

 of the umbel usually 2, at first enclosingthe flowers, 

 acuminate, deciduous; umbel erect; pedicels becom- 

 ing rigid, 6"-io" long; flowers white; perianth- 

 segments oblong, obtuse, 2"-3" long; filaments 

 lanceolate-subulate; ovule 1 in each cavity; capsule 

 deeply 3-lobed, about 3" broad, ii"-2" high, its 

 valves not crested ; seeds globose, black, smooth. 



In rich woods, New Brunswick to Minnesota, North 

 Carolina, Tennessee and Iowa. Often grows in large 

 beds. Three-seeded leek. Ramps. June-July.

 or Rush-garlic. Fig. 1243. 



Allium sibiricum L. Mant. 2: 562. 1771. 



Bulbs narrowly ovoid, clustered, 1' high or less, 

 their membranous coats not fibrous-reticulated. 

 Scape rather stout, 8'-2° high, bearing below the 

 middle 1 or 2 elongated linear terete hollow 

 leaves about i" in diameter, or the leaves all 

 basal; bracts of the umbel 2, broadly , ovate, 

 veiny; umbel many-flowered, capitate, the pedi- 

 cels 1 "-3" long; flowers rose-color, longer than 

 the pedicels; perianth-segments 4"-6" long, 

 lanceolate, acuminate; stamens much shorter 

 than the perianth; filaments subulate, half- 

 terete ; ovules 2 in each cavity of ovary ; capsule 

 obtusely 3-lobed, half as long as the perianth.
