very villous ; leaves lanceolate or narrowly-lanceolate, 1-3 dm. 

 long, acute or short-acuminate, ciliate, villous on both surfaces or 

 glabrate above, somewhat narrowed near the base ; sheaths vil- 

 lous like the stem, 1-3 cm. long; involucre of 1-2 bracts like the 

 leaves but smaller; flowers blue, 1.5-2 cm. broad; pedicels usu- 

 ally densely villous ; sepals oblong or elliptic-oblong, 7-9 mm. 

 long, villous, acute or acutish ; capsules oblong, 4-5 mm. long,

Upper districts and mountains of Georgia ; Chapman, two col-

 straight or nearly so, simple or sparingly branched above; leaves 

 narrowly lanceolate or linear-lanceolate, 1-3 dm. long, usually 

 minutely pubescent, or rarely glabrate, acuminate, flat; sheaths 

 1-2 cm. long, ciliate ; involucre of two lanceolate leaf-like bracts, 

 one of which is at least one-half smaller than the other ; flowers 

 blue, small, 2-2.5 cm. broad; pedicels slender, 1-I.2 cm. long; 

 sepals ovate or oblong, sometimes apparently lanceolate by the invo- 

 lute edges, 5-6 mm. long, pilose or villous, obtuse, hooded, often 

 minutely glandular ; petals sub-orbicular or orbicular-ovate ; cap-

 straight or almost straight stem, narrower and thinner leaves and 

 usually less pubescence. 



Last July I found this plant abundantly on Paris mountain, 

 near Greenville, South Carolina. It grew on the upper slopes and
