as the more or less incurved anthers : berry not seen. 
. In moist woodlands and river bottoms, Georgia to Alabama and Louisiana.

14. Trillium eréctum L. Scapes solitary or clustered, 3-6 dm. tall, smooth : bracts 
3; blades rhombic, often broader than long, 6-16 cm. in diameter, acuminate at the apex,

ments pink or reddish : anthers often 8-11 mm. long, with pale connectives colored like 
the filaments : ovary pink or red: berry about as large as that of the next preceding spe-
