264 ALLIACEAE 



9. Allium arenicola Small. Bulbs nearly 1 cm. long, usually solitary, with fibrous 

 outer coats, the fillers loosely woven : leaves basal ; blades very narrowly linear, becoming 

 almost filiform, about as long as the scape or shorter : scapes sometimes several together, 

 1-3 dm. tall, more or less curved : umbels erect, 10-30-flowered : pedicels 5-10 mm. long, 

 slender : perianth deep pink, not tubular : sepals and petals linear or narrowly linear-lan- 

 ceolate, about 4-5 mm. long, acute or acuminate, very delicate : filaments dilated below : 

 capsules lobed, the valves not crested. 



In sandy soil, Arkansas, the Indian Territory, Mississippi and Texas. Spring. 



"TE'lO. Allium Helleri Small. Bulbs ovoid, usually 2 together, with fibrous outer coats, 

 but the fibers closely woven : Leaves basal ; blades linear, 1-2 dm. long : scapes as long 

 as the leaves or overtopping them, terete or nearly so : bracts 2-3, ovate or ovate-lanceo- 

 late : umbel erect, few- or many-flowered : pedicels slender, 8-15 mm. long, erect or ascend- 

 ing : perianth white or rose-colored, 6-7 mm. long, tubular : sepals and petals oblong- 

 lanceolate to elliptic, rather blunt, relatively firm : filaments granular, barely dilated 

 above the base : capsules 3-5 mm. broad, included, the valves crestless. 



On prairies, usually in dry soil, Nebraska to Colorado, Texas and Arizona. Spring. 



"\: 11. Allium Cuthbertii Small. Bulbs ovoid, with coarse-fibrous outer coats : leaves 

 basal ; blades narrowly linear, 1-3 dm. long, slightly channeled : scapes usually solitary, 

 mostly longer than the leaves : umbel erect, often 10-30-flowered, subtended by 2-3_very 

 delicate long-acuminate bracts: pedicels slender or filiform, 2-2.5 cm. long: perianth 

 white : sepals and petals linear-lanceolate, 6-9 mm. long, acuminate, delicately striate : 

 filaments subulate above a dilated base which is somewhat coherent with the sepals and 

 petals : capsules 4-5 mm. wide, the valves crested. 

 In sand, Georgia and Florida. Spring. 



2. VALID ALLIUM Small. 

 Scapose herbs giving oft' a strong alliaceous odor, with clustered bulbs. Leaves basal, 

 mostly 2-3: blades relatively broad, appearing before the scape, thickish. Scape simple. 

 Flowers perfect, in a terminal umbel subtended by 2 bracts. Perianth white or pale, per- 

 sistent : sepals and petals distinct or nearly so. Stamens 6 : filaments slender : anthers open- 

 ing introrsely. Ovary sessile, 3-celled : stigma depressed. Ovules solitary in each cavity. 

 Capsule loculicidal, 3-lobed. 



1. Validallium tricoccum (Ait.) Small. Bulbs clustered, with fleshy-membranous 

 outer coats : leaves 2, basal, vernal, disappearing before the flowers appear; blades oblong 

 to oblong-elliptic, 1-3 dm. long, acute, tapering into petiole-like ba.ses : scapes 1-4 dm. tall, 

 often curved, terete: umbel erect, subtended by 2 bracts: pedicels numerous, 1-1.5 cm. 

 long, nearly straight : perianth wliite : sepals and petals oblong to oval, 6-7 mm. long, 

 obtuse: filaments subulate-lanceolate, about as long as the perianth : capsules 3-lobed, about 

 6 mm. broad : seeds globose, about 3 mm. in diameter, black, smooth and shining. [Allium 

 tricoccum Ait.] 



In moist woods and on hillsides, New Brunswick to Minnesota and Georgia. Summer. 



3. NOTHOSCORDIUM Kunth. 

 Scapose herbs resembling Allium, but without the characteristic odor. Bulbs mem- 

 branous coated. Leaves basal : blades narrow. Scape topped by a simple few-rayed umbel, 

 this subtended by 2 bracts. Flowers perfect. Perianth yellow, greenish or white, withering 

 but persistent : sepals and petals 6, narrow, 1 -nerved, distinct or nearly so. Stamens 6, 

 adnate to the base of the sepals and petals : filaments subulate or filiform : anthers narrow; 

 opening introrsely. Ovary 3-celled : style filiform, jointed near the base : stigma capitate. 

 Ovules several in each cavity. Capsule 3-celled or 3-lobed, loculicidal. Seeds black, 

 angled, or flattened. 



1. Nothoscordiumbivdlve (L.) Britton. Bulbs 1-2 cm. long : leaves basal ; blades 

 narrowly linear, 1-4 dm. long : scapes 1-4 dm. tall, commonly overtopping the leaves : 

 umbel erect, subtended by several membranous acr.te or acuminate bracts, 3-15-flowered : 

 pedicels slender, 2-5 cm. long, straight : perianth white, delicate : sepals and petals oblong- 

 lanceolate or narrowly oblong, acute, 10-12 mm. long : filaments shorter than the perianth : 

 capsules obovoid or rarely broader than high, 4-6 mm. long. [Allium striatum Jacq.] 



In sandy soil, Virginia to Nebraska, Florida, Texas and Mexico. Spring. False Garlic.
