 lanceolate, acuminate, 6-8 mm. long, usually with red midnerves : stamens not surpassing 

 the perianth : capsules 5-6 mm. broad, the valves crestless. 



On gravelly hillsides or in grassy places, Texas to Arizona and Mexico. Summer and fall. 



5. Allium Caiiadense L. Bulbs with fibrous outer coats : leaves basal ; blades nar- 

 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 at the base, entire, about as 

 long as the perianth. 



In meadows and fields, Maine to Minnesota, Florida and Louisiana. Spring. MEADOW GARLIC. 



6. Allium continuum 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 cm. broad : sepals and petals lanceolate or almost linear, notched at the apex : fila- 

 ments dilated below : capsules lobed, the valves not crested. 



In and near the Ocmulgee river-swamps, Georgia. Spring. 



7. Allium mutabile Michx. Bulbs with conspicuously fibrous outer coats : leaves 

 basal ; blades narrowly linear, 1-4 dm. long, channeled : scapes 2-5 dm. tall, usually sur- 

 passing the leaves : umbels erect, subtended by 2-3 ovate to oblong long-acuminate 

 bracts: 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.

 perianth, the valves not crested.
