 funnelform, withering-persistent, the tube about as long as the 6 oblong lobes. 

 Stamens 6, inserted on the throat of the perianth; filaments dilated, united to the 

 middle or above into an erect crown-like tube with toothed lobes alternating with 

 the linear-oblong anthers. Ovary sessile, 3-celled; ovules several in each cavity; 

 style filiform; stigma 3-grooved. Capsule membranous, 3-angled, loculicidal. 

 Seeds few, large, oval, black. [Greek, referring to the crown.] Two species,

 0.6-3 cm - l n g; perianth 2-3 cm. long, the lobes about as long as the tube; 

 filament-tube about I cm. long; style about as long; capsule 8-12 mm. high; 

 seeds thin, narrowly winged. Prairies, Kans. to Tex. March-April. 



6. LILIUM L. 



Tall bulbous herbs, with simple leafy stems, and large erect or drooping 

 showy flowers. Perianth funnelform or campanulate, deciduous, of 6 separate 

 spreading or recurved segments, each with a nectar-bearing groove at its base 

 within. Stamens 6, hypogynous; filaments filiform or subulate; anthers linear, 

 versatile, their sacs longitudinally dehiscent. Ovary 3-celled; ovules numerous; 

 style long, somewhat club-shaped above; stigma 3-lobed. Capsule loculicidally 

 dehiscent. Seeds numerous, flat, horizontal, packed in 2 rows in each cavity. 

 [Latin, from the Greek name of the Lily, said to be from the Celtic /z, white.]
