rowly linear, 1-5 dm. long, rounded on the back : scapes 2-6 dm. tall, finely ridged in age: 
umbel subtended by 2 or 3 ovate membranous bracts, most of the flowers replaced by bulb- 
lets: pedicels few, slender: perianth pink or white: sepals and petals oblong-lanceolate, 
obtuse, 4-5 mm. long, or sometimes longer: filaments dilated atthe base, entire, about as 
long as the perianth.

6. Allium contínuum Small. Bulbs with fibrous outer coats: leaves basal; blades 
narrowly linear, often shorter than the scape, early withering: scapes often tufted, 3-4 
dm. tall, topped by a head of ovoid or oblong-ovoid bulblets, subtended by an involucre of 
3 reflexed acuminate bracts ; bulblets sending out relatively stout scapes 1-2 dm. long: 
flowers few, accompanying the bulblets: pedicels slender, 1-3 cm. long: perianth pink, 
about 1 em. broad : sepals and petals lanceolate or almost linear, notched at the apex : fila- 
ments dilated below: capsules lobed, the valves not crested.

7. Allium mutàbile Michx. Bulbs with conspicuously fibrous outer coats: leaves 
basal ; blades narrowly linear, 1-4 dm. long, channeled: scapes 2-5 dm. tall, usually sur- 
peus the leaves: umbels erect, subtended by 2-3 ovate to oblong long-acuminate 
racts: pedicels often numerous, 1-2.5 cm. long, slender: perianth white, pink or rose- 
colored: sepals and petals lanceolate or ovate-lanceolate, acute or acuminate, 5-7 mm.
