Trillium stamineum n. sp. 



Stem erect from a horizontal rootstock, solitary or clustered, 

 I _^dm tai^ pubescent near the top : leaves sessile, ovate-lanceo- 

 late to broadly ovate, 5-8 cm long, acute or acuminate, mottled 

 and usually somewhat pubescent on the veins beneath : flowers 

 sessile, fetid : sepals broadly lanceolate to elliptic, 2~3 cm long, 

 acute or acutish, deeply tinged with purple, spreading or finally 

 reflexed : petals lanceolate, about as long and one-half to two- 

 thirds as wide as the sepals, dark purple, widely-spreading, 

 somewhat twisted : stamens one-half to two-thirds as long as the 

 petals: anthers stout, i.5-i.8 cm long, straight, dark purple: 

 filaments short, dark purple : stigmas slender, spreading and 

 recurved : berry ovoid, pale purple, about i cm in diameter. 



In rocky woods, central Alabama. Blooms in Cullman county, 

 Alabama (type locality), about the middle of April. 



Trillium stamineum finds its nearest relative in T. sessile L., 1. c, but 

 may be easily recognized by its pubescent stem, widely-spreading, twisted pet- 

 als, unpleasant odor, larger stamens, and very short filaments. 



The type material is preserved in the Biltmore Herbarium. 



Trillium ludovicianum n. sp. 



Stem erect from a horizontal rootstock, solitary or clustered, 

 8 cm -2 dm tall, smooth : leaves sessile, ovate to broadly ovate, 5~8 cm 

 long, acute or obtuse, mottled : flower sessile : sepals lanceolate 

 to broadly lanceolate, 2-3. 5 cm long, acute or obtuse, tinged with 

 purple at the base, spreading or finally reflexed : petals linear to 

 linear-lanceolate, 3~6 cm long, scarcely as broad as the sepals, acute 

 or acutish, purple or greenish above and purple at the base, 

 spreading : stamens one-fourth to one-third as long as the petals : 

 anthers erect, straight or slightly recurved, i.2-i.8 cm long : fila- 

 ments about 4 mm in length : stigmas slender, spreading and 

 reflexed : berry ovoid, pale purple, about i cm in diameter. 



In low, rich woods, Louisiana. March and April. 



The species with which Trillium ludovicianum is likely to be confounded 

 are T. viride Beck, 19 and T. lanceolatum Boykin. 20 From the former it may 

 be easily separated by its smooth stem, and from the latter by its shorter stem, 

 broader leaves, broader sepals, shorter filaments and straight anthers.
