4. XEROPHYLLUM Michx. 



Rigid herbs, with short woody rootstocks. Stems leafy, simple. Leaves numerous :

 sepals and petals 5-7-nerved, glandless, persistent. Stamens 6, not surpassing the perianth : 

 filaments subulate : anthers 2-celled ; sacs extrorsely dehiscing. Ovary 3-celled : styles 3,

 blades narrowly linear, rigid, 1-5 dm. long or much shorter above on the stem, long-atten- 

 uate : racemes usually many-flowered, 5-15 cm. long, conic while in flower : pedicels 

 slender, ascending or erect at maturity, 1.5-2 cm. long : perianth white : sepals and petals 

 ovate or oblong-ovate, 5-6 mm. long, obtuse : capsules oval-ovoid, 4-5 mm. long. 



In pine lands. New .Jersey to Florida and on mountain slopes and summits, North Carolina and 

 Tennessee. Spring and summer. Turkey-beard. 



5. CHAMAELIRIUM Willd. 



Glabrous fleshy caulescent herbs, with bitter aromatic rootstocks. Leaf -blades various : 



basal broadened upward, the cauline narrowed upward or linear above, all thickish. Flowers 



dioecious. Racemes elongated, slender, simple, spike-like. Perianth white : sepals and 



petals narrow, 1-nerved, nearly ec^ual, distinct. Stamens 6, much reduced in pistillate 



flowers : filaments filiform : anthers 2-celled Ovary 3-celled. Ovules 6-12 in each cavity.
